Circular and irregular shape of record-breaking galaxies observed by JWST hints onto the much larger distance between them and Earth. Thus again supporting the idea of light scattering and tired light instead of Big Bang.

     The marvel of modern astrophysics, James Webb Space Telescope is making discovery after discovery and many of them puzzles the astrophysicists. Too many galaxies too early (according to Big Bang time line), little red dots with impossible velocities of gas near supermassive black hole (and such a black hole itself is too early for the young Universe etc.). While JWST already made several discoveries of galaxies at Z=13 and even 14, they all looks a little strange - all looks like circles, not even one has a classical oval shape (both spiral and elliptical galaxies at low resolution must be ovals). There is very low probability that all record-breaking galaxies are spirals observed at almost perpendicular to plane angle (that would make it looking perfect circle. 

     The explanation seems obvious - resolution of telescope is limited and by no means may JWST see details below its diffraction limit - approximately 3*10exp(-7) radian for wavelength of 2 um [1]. However, there is a problem here. Since according to Big Bang theory at high Z the difference at the observed distance with Z will be smaller and smaller, those galaxies are virtually all at the same distance of around 13 billions of light years. Even galaxy with Z=7 is actually 12.9 billions of light years away from us [2] - no real difference from the point of view of resolution of telescope. In order to evaluate the change of resolution from telescope to telescope, it is necessary first to see the galaxies at relatively high Z recorded by the predecessor of JWST - Hubble space telescope. Of course due to smaller mirror and absence of mid-IR capabilities it can not see galaxies at Z=13 and up (with some exceptions) but since galaxies with z=7-9 are almost at the same observational distance (~13 billions of light years if Big Bang is accepted) the comparison may be fair. The picture below is taken from [3] and the galaxies on photo are all with verified Z~8, and galaxies number 1,2,3,5 are looking like ovals.


It is easy to see, that Hubble Telescope indeed made photos of galaxies which looked as they should be - despite some of them are almost circles, many are ovals and even elongated ovals. Those galaxies if believe to Big Bang are all at ~13 billions of light years away. 

James Webb Space Telescope has larger mirror and thus must have better resolution (approximately 3 times better). It is clearly observed in the nearby Universe (say for Z~1). But since the galaxies at Z=12,13, 14 and up are almost at the same distance as galaxies at Z=8, JWST must deliver much better resolution of those galaxies (3 times better) and must see normal galaxies shapes (not dull circles all over again). Yet the discovery after discovery delivers the galaxies which looks like plain circle or irregular circle. The examples are: galaxy at Z=13 [4]

Galaxy at Z=14 [5]


Another galaxy at Z=13 [6]:



Another example of 4 galaxies all at the distance of ~13 billions of light years and all looking like circles [7]:


Sometimes galaxy with high Z has the elongated shape but it is situated in the field of strong lensing (so obviously distorted by lensing) [8]:


No improvement in resolution may be seen in resolution, despite from Big Bang idea they all are at approximately the same distance (around 13 billions of light years) as well as galaxies with Z~8 which are observed more or less normal already by Hubble telescope. Compare to the enormous improvement in resolution (Hubble made photos for upper row and JWST is for lower row) for galaxy cluster at Z~0.4 [9]:



Even assuming for high Z Hubble space telescope made pictures at central frequency around 1.6 um versus 2 um for James Webb Space Telescope (resolution is 1.25 worse for wavelength of 2 um compare to 1.6 um) the improvement in resolution still should be at least (6.5/2.4)*(1.6/2.0)=2.167 times (provided the Big Bang is correct, no light scattering is allowed and galaxies are at approximately the same distance of ~13 billions of light years). But obviously JWST only provides enormous improvement only at relatively low Z, not at high Z.

On the contrary, if the tired light hypothesis is accepted [10] situation changes dramatically. Now the distances for Z~14 would be much larger (Z~1 corresponds to ~10 billions of light years, Z=3 corresponds to ~20 billions of light years, Z=7 corresponds to ~30 billions of light years and Z=15 corresponds to ~40 billions of light years), so it is obvious that galaxies at high Z may be resolved poorer and it would need many hundreds of hours of accumulation to get the spectra (and that time must be almost the same in the case of Big Bang is right). Even more, the inevitable light scattering [10] will make the far galaxies blurred to the extent they may be only seen as a circle (and this circle is only having information about the light scattering properties, not initial galaxy oval view) [10,11]


It seems that even visual appearance of galaxies at high Z hints toward the paradigm shift from Big Bang cosmology to tired light cosmology. Both standard objects like supernovae at high Z (already visible at Z=3.6 and JWST is continuing the search) and non-standard objects like galaxies hints toward this decision. (The galaxies may theoretically be visible as circles because in principle it is possible from point of view of Big Bang that galaxies at Z=13-14 are so primordial, that the shape is essentially spherical cloud, so the shape must be visible as circle only). The spectra from those high Z galaxies however show a good content of oxygen, which means that stars already experienced many supernova events and galaxy shape is also expected to be one of the few standard ones.

Axionic dark matter possibility from light scattering demonstrated by JWST for high z objects.

 The light scattering is observed by JWST through blurring of far galaxies at z~10-14 [1], through 2-4 times larger than diffraction limit of telescope supernovas [2] and through analysis of little red dots [3]. In [1,3] the empirical formulas are discussed which depict the light scattering and it was possible to come to the conclusion that the energy loss on each step is proportional to energy (key assumption) with coefficient α=2*10exp(-12). From that coefficient it is clear that the particles scattering light are enormously light with approximate evaluations of total energies of femto to pico eV (only for such light particles the energy loss of say green photon would be so small as it is necessary). Heavier particles like today approximation of axions as particles with micro-eV total energies will drain the energy of photon much faster and thus created too strong scattering which is not observed. 

However, application of quantum mechanics general ideas will allow to evaluate the properties of such "dark matter" (better be called almost completely transparent matter, because it is after all interacting with light). For total energy of 10exp(-15) eV the energy expressed in Joules would be 1.6*10exp(-31) Joule, for total energy of 10exp(-15) eV the energy expressed in Joules would be 1.6*10exp(-34) Joules. The effective mass may be estimated using the relation E=m*c2 (the relativistic mass, because such particles is moving with speed very close to c). For pico-eV particle it is 1.78*10exp(-48) kg, for femto-eV particle it is 1.78*10exp(-51) kg. The pulse may be calculated using E=p*c relation: for pico-eV particle the pulse is 5.33*10exp(-40) kg*m/s and for femto-eV particle the pulse is 5.33*10exp(-43) kg*m/s. Since pulse is known the important characteristic of the particle - de-Broglie wavelength may be easily found λ=h/p   here h is Planck constant. For pico-eV particle de-Broglie wavelength is 1.24*10exp(6) meters and for femto-eV particle it is 1.24*10exp(9) meters (1/3 of Earth to Moon distance). 

For such enormously large de-Broglie wavelength no doubt the light is not interacting with the particle easily, the cross-section of the interaction may be evaluated as the square of diameters of "particle" size. For photon it would be wavelength (500 nm for green photon) and for particle which scatters light it is de-Broglie wavelength. Then the cross-section for pico-eV particle would be [500*10exp(-9)/1.24*10exp(6)]2=1.6*10exp(-35) and for feemto-eV particle it would be 1.6*10exp(-41). 

How frequently the photon is scattered on the route from supernova to the Earth to have the scattering parameter of 2*10exp(-12)? From the formulas outlined in [1] and assuming for z=1 supernova the distance between the star and Earth of 7.731 light years (7.314*10exp(25) meter) we may have: after N scatterings

EN/Eo=1/(1+z)=(1-α)N   ln(1/(1+z))=ln(0.5)=N*ln(1-α)~-N*α

and N=3.47*10exp(11) for the distance traveled of 7.314*10exp(25) meters. Therefore the average distance traveled between the interactions is L=2.16*10exp(14) meter (approximately 8.33 light-days). 

In order to evaluate the mass density of such axionic dark matter the assumption is as follows: during the travel of 8.33 days the effective volume of the photon has covered is V= π*λ2/4*L , here λ is the wavelength of the light  and the mass of the axions in this volume is mass of one axion divided by the cross-section (because it is necessary to meet enormous amount of axions to interact with only one of them). V=42.4 cubic meters and mass density is 2.62*10exp(-15) kg/cubic meter for pico-eV particles and 2.62*10exp(-12) kg/cubic meter for femto-eV particles. 

This value is comparable to the interstellar visible matter (mainly protons) of 1.67*10exp(-15) kg/cubic meter [4], less than the total mass density of Milky Way (2*10exp(-10) kg/cubic meter [5]) and  larger than the calculated mass density of dark matter in the halo around Milky Way (0.2-0.4 GeV per cubic cm [6]) which would be 3.55-7.1*10exp(-22) kg/cubic meter. 

The values obtained are reasonable and interestingly, the axionic dark matter interacting with light will be looking close to what astronomers are expecting - it must form halo. Because the particles are interacting with photons and so light, they are virtually pushed away by any photons (even microwave ones) from the stars, away from galaxy (full of photons) but due to some gravitational interaction they can not really lost the galaxy completely. They are indeed forming the halo around galaxy (and even more so pronounced halo around galaxy clusters) - an exactly as it is expected from gravitational consideration of light bending and too fast galaxy rotation. The estimated value of the mass density of those particles from light scattering is also reasonable - not really small and not enormously large (the distribution of them in halo is a separate and very difficult problem). However, the enormously small effective mass of them (energy of pico to femto eV) deemed the possibility of detection of them on Earth virtually impossible - they are sweeped out of Solar system by photons. Unless they are generated in the Sun itself (and in this case the stream of them directly from Sun similar to neutrinos stream is expected) they are only be possible to research using the light scattering from far-far stars, supernovas and galaxies.

The higher Z, the stronger the effect of light scattering present in the supernova images. Supernova at Z=3.6 looks gigantic.

 James Webb Space Telescope is continuing to break all the records and now it shows  excellent images of far supernovae. As it is already described in this blog (see previous posts) and in the publications [1] the effect of light scattering is more and more pronounced. Recent discovery of the far supernova at Z=3.6 [2] emphasizes the effect very clearly - the supernova visible angular size is now comparable to the size of galaxy where it originated. Picture is taken from [2]

Compare to usual visual size of the supernovae at small Z, where they are close to the diffraction limit of the telescope this supernova has an enormous visual size of 1.05*10exp(-6) radian, while the diffraction limit of JWST for this wavelength of 2 um (F200W filter) is 0.3*10exp(-7) radian, more than 3 times smaller compare to point source object angular size. 

As it was calculated before in this blog, any supernova at maximum brightness (and usually they are found at around this moment) must be the point object (and especially at high Z it is by no means may be resolved). The idea that supernova is "illuminating" part of the galaxy and has the larger angular size because of the light scattering inside the galaxy of origin is easily rejected by observing the close supernovae - they are exactly  a dot in the galaxy, no "illumination" of the galaxy is present (picture taken from [3])



Comparison of pictures taken from [2] and [3] clearly shows that while the close supernova has an angular size negligible compare to the size of galaxy or even the center of the galaxy, the far supernova has a gigantic angular size, the same as center of galaxy and close to the size of the host galaxy. By no means may be this phenomenon explained in simple terms. The angular resolution of the telescope itself was checked many times and for really feeble and small objects at z=0 (brown dwarfs at the outskirts of Milky Way [4]) it is precisely equal to the famous formula: α=λ/D, where α is diffraction limit of the telescope, λ is the wavelength (2 um in this case), D is the diameter of the mirror of the telescope (6.5 m for JWST), should be 3*10exp(-7) radian. Of course, for such big distances at Z=3.6 the angular size of the galaxy itself is also very small, but direct application of the resolution formula shows that the supernova must looks like this:


Observed deviation is present not only for supernovae but for all the objects which must be point objects for high Z. Below is the plot of angular sizes of the point-like objects as they are observed by JWST as a function of Z:

For Z in the range 4-10 the angular size of the center of the little red dots was taken (they have an active galactic nucleus in the center which should be point object, see [4]). For Z higher than 10 the center of galaxy observed is a point source already, the distance is too high. Despite the big scattering, it is clear that the point-like objects are observed with some angular size, what is confirming the idea that light is scattered at high Z. The curve is fit by the formula derived from tired light idea of multiple scatterings outlined in [5]. 

The explanation of such a phenomenon may be actually not involved really new physics - the far objects may be inevitably blurred by the presence of the microgravitational lensing (which also must influence the light curves for supernovae, see [6]). Another explanation is that there is no Big Bang at all, and the light is scattered due to multiple events of scatterings (when this number N is enormously large, say trillions, the energy drain - red shift- is proportional to N, but light scattering is proportional to sqrt(N), similar to diffusion equation, see [1,5] for derivation of the formula). Blurring of images is almost completely absent at Z~0 (well below diffraction limit of even future generations of telescopes) but finally observed because the light travelled enormous time (well above the life-time of the Sun!) and even extremely small effect is now clearly pronounced. This observation of light scattering is the strongest so far hint toward the presence of new physics (fifth force in the gap between electromagnetism and gravity) and in line with other hints outlined by author in his books [7,8]

Little red dots and brown dwarfs – demonstration of the light scattering by point-like objects.

 

Discovery of little red dots was an important step forward in understanding of the nature of the Universe. While the discussion of the nature of those little red dots is not yet finished, the consensus is that they are most probably not an exotic galaxies (or even other objects of completely unknown nature) but rather observed from very high distances quasars (active galactic nucleus) without clearly seen the rest of the galaxy [1]. The typical size of the AGN would be around 1 parsec [2], which is 3.26 light years. For the distance of 13 billions of light years (at least, in Big Bang Cosmology) for z above 4 the angular size at Earth would be only 3.26/13*10exp(9) = 2.5*10exp(-10) radian and well below the diffraction limit of James Web Space Telescope (3*10exp(-7) radian for wavelength of 2 um, filter F200W). This is clearly a point-like object for high z.

               Initial observations of the little red dots was found to be heavily contaminated by the brown dwarfs from the outskirts of Milky Way (those stars are not luminous and are not creating the usual projectile-like pictures on the image). Yet the presence of them on the same image as little red dots allows to compare directly the close and far point-like objects ( at a distance of 10 parsec even JWST can not resolve the star and it must be at diffraction limit of the telescope). The problem is that those point-like objects are looking differently on the image, one has much larger angular size compare to former.

Here is how brown dwarf looks like [3]:


The square is 2.4 arcsec each side and the size of 0.1” is also shown. The angular size of the brown dwarf for filter F115W is 0.058” or 2.8*10exp(-7) rad. For the center wavelength of 1.15 um the angular resolution (diffraction limit) of JWST would be 1.15 um/6.5 m=1.8*10exp(-7) rad. It is clearly seen that the angular size of brown dwarf is close to the diffraction limit of the telescope.

Here is how little red dots with Z=7.41 and 7.48 looks like for the same size of the squares 2.4” on one side [4]:



Even without any measurements it is clearly seen that those point-like objects are having much larger angular size (for the same filter F115W: 0.12” – 0.16”, 5.8-7.8*10exp(-7) rad, which is 3-4 times larger than the diffraction limit of the telescope).

               Those observations once again confirmed that JWST is working at full capacity – no problems with mirrors tuning or trembling because of small meteorites striking. The close point-like objects when they are very dim and not saturating the detector (projectiles for stars being photographed) are having the angular size exactly as expected. But very far point-like objects imaged at the same time are having much larger angular size. This is only possible if the light itself is scattered (this property is predicted for Tired Light Theory and completely impossible in Big Bang Cosmology). Despite this is not real disproof of Big Bang (because after all light may be scattered without loss of energy by unresolved Einstein crosses or some refraction phenomena for the light passing through invisible nebulae) it is a very strong hint toward direction of search for New Physics (beyond Einstein-Schrodinger and Standard Model) [5,6].

DESI and accelerated expansion of Universe - DESI results confirm the absence of accelerated expansion. Explanation - wrong interpretation of the results on supernovae.

     The idea of the absence of the dark energy as it was discovered in the last century using the data on supernovae brightness expressed in previous blogs [1,2] got unexpected confirmation from DESI - big collaborative project targeted the nearby galaxies (up to around z=3) [3]. Despite the author rejection of Big Bang together with "dark energy" being experimentalist I am more concerned in absolute accuracy of the interpretation of the experimental results and the famous Hubble curve which lead to discovery of the dark energy in last century [4] was wrongly interpreted from the very beginning (see [1]).

    Problem with interpretation of the brightness of the supernovae lies in the assumption of the absolute absence of new indiscovered yet properties of photons. In this case indeed the light scattering is absolutely impossible, the image of the far supenovae will be always at the diffraction limit of the telescope and the brightness of the image would be inversely proportional to the distance square. In this case any deviation of the brightness from established laws (dependence magnitude from red shift z) must be interpreted as some problems with space-time (thus the "discovery" of the "accelerated expansion"). But in reality the nature is by far reach than we may imagine, some new properties of photons are present and they lead to light scattering. This light scattering, invisible on Hubble images (resolution is too small) is readily seen by the JWST (much better resolution) and thus it lead to the spread of the circle of the image beyond the diffraction limit (and brightness is dimmer than it should be), see [1,2].

Despite I am personally think that the Big Bang is absent too, the tired light cosmology postulates that the red shift is extremely uniform with distance in the stationary Universe. So no problems with space-time is possible (no accelerated Z-shift in the neighborhood of Earth is possible). If instead of uniformity of expansion it is considered how z-shift behaves with distance I would completely agree with what DESI found - z-shift in far distances and near distances has exactly the same dependence on the distance - no "accelerated expansion of Universe".

Light scattering observed on supernova type 1A - no "dark energy", the Hubble findings should be re-analysed.

 In a recent publication [1] the only so far discovered by JWST supernova type 1A  at z=2.9 (confirmed by spectroscopy [2]) was successfully plotted on the famous plot magnitude versus red shift, well known from Hubble telescope time and considered as a proof of the discovery of the "dark energy" [3]. The plot is shown below:


The fact that this supernova fits so well the previous plot does not support the idea of "dark energy" or "accelerated expansion of Universe", but instead demonstrates that the original explanation of the deviation from straight line was completely wrong. This is not a space-time problem (the "expansion" rate changes), but much more trivial phenomenon - the light itself is not ideal and for billions of years of propagation (more than 10 billions for z>1) starts to be scattered a little. The visible angular size of the supernova type 1a (very standard one, all the properties are well known) is at least 6 times larger than it should be for point source (see [4]), well above any errors or uncertainties. 

Why this is so important is shown below:

The fact that high z supernovae with visibly clearly seen much larger than it should be angular sizes [5] are so well fit on the old plot is the confirmation of the fact that in reality the light scattering was observed even at Hubble telescope time, it was merely completely wrongly interpreted. In this sense the observations of JWST are completely consistent with Hubble telescope findings, but additional information obtained due to much higher resolution points onto the necessity to carefully re-interpret the old data and theories. Most probably "dark energy" and even "Big Bang" are not real, just the temporal fit of the incomplete data.

Time-dilation for supernova in the case of tired light hypothesis.

 Abstract.

One of the most important confirmation of the Big Bang theory was the discovery of the time broadening of the light curve of the far supernovas (supernovas 1A, standard candles, at the distances around Z=1). From straightforward consideration in the complete absence of light scattering it can not be explained in any other way but by Doppler-like effect which in this case called time dilation and seemingly confirming the Big Bang. However, the hypothesis of tired light [1] also allows the light being diffusion-like scattered on travel from supernova thus allowing change in distance traveled and allowing corresponding time broadening of the light curve (the fastest photons goes straight path, later arrived those which due to multiple scattering – diffusion-like in perpendicular direction – first traveled away from direct line, than returned back, possible many times and thus got a big enough increase in distance to generate perceptible – few days- delays at arrival). Problem with this mechanism is that gives  smaller time delays compare to time dilation directly observed [1]. The gravitational microlensing may be involved  and due to additional change of distance, Shapiro effect and brightening some parts of the image of supernova (3 separate effects)  will make the light curves broader and thus explaining the time dilation observed.

Introduction.

Discovery of the time broadening of the supernova type 1A (standard candle) light curves was instantly interpreted as a proof of the Doppler time dilation (the processes seems slower as a factor 1+z because the objects are moving away faster and faster as they are further from Earth). Indeed, up to z~1 (the best Hubble may do in supernova discoveries) the broadening of the light curve (time dilation) follows this simple law (broadening~1+z) and it was considered as a final confirmation of Big Bang. However, time dilation is also possible in tired light theory (the photons experience diffusion-like process and some will arrive few days later compare to the ones traveled the straight path). The real difference between the time dilation as inferred from Big Bang Theory or from diffusion-like tired light approach will be revealed at z~3 (and supernovas with z~3 are already detected by James Webb Space Telescope, so the complete light curve measurement may be on its way right now). This is because according to Doppler-like time dilation the law 1+z will persist and at z~3 the time dilation would be 4 times compare to z=0 (the light curve width for supernova type 1A must be around 100 days instead of usual 24 days at z=0); while for tired light the effect will be much smaller (light scattering quickly saturates with z [2]) and width should be only ~40-50 days (more than 2 times narrower). The difference between ~100 days and ~40 days is huge and for higher Z it will be even larger – while the supernovas at z~12 in Big Bang cosmology must shine bright around 260 days (more than half a year) the  same supernovas for tired light idea will shine for ~60 days (see how fast the scattering curve saturates in [2]). Obviously if the time dilation will follow 1+z law up to those  high z the Big Bang will be fully confirmed and any tired light hypothesis completely eliminated. Interestingly this observation is due in very close future – JWST is actually observing some supernovas at z=3.8 already [3] and this is only the beginning. But for right now it is necessary to explain how tired light may explain already observed time dilation for supernovas with z~1.

Main part.

               The light curves of the supernovas are measured a lot, but for the further supernovas some unexpected factors may contribute to the width and make the curve broader what looks like time dilation. It may be influence of gravitational lensing on  a scale smaller than generate the resolved multiple images (so called microlensing), with corresponding Shapiro effect and strong influence of the wavelength of the image taking detector since the light curve at one frequency is not the same as light curve for different light color (and red shift at high z makes it even more complex problem, it is necessary to recalculate light curve at different wavelengths back to z=0). It may happened that the time dilation is a result of multiple factors, which working together make the light curve broader than it is.

               At first, the supernovas type 1A are not completely standard. They may be broadly divided into brighter ones and dimmer ones [4]. Because of the range of white dwarfs leading to explosion, some supernovas type 1A are brighter and some are dimmer (but both are type 1A because of spectroscopic features). What is very important for time dilation the brighter supernovas type1A are fading slower (not very much but well resolved by the light curves). Since the brighter supernovas are easier to spot at the high z (for Hubble supernovas at  z=1 are already approaching the limit of detection), the far supernovas have a selection bias toward the broader light curve.

               Another important difference between the  modern model of the light propagation (no light scattering is allowed) and tired light hypothesis is in the way the light propagating from supernova experiences gravitational bending. The real size of supernova type 1A at the moment of the maximum brightness (they usually discovered around this moment)  is relatively small compare to typical interstellar distances (distance Sun to Alpha Centauri is 3.8*10exp(16) meters). The real size of supernova is only 2-3 light days at maximum brightness - something like 3-4.6*10exp(13) meters [3] (just around 50 times larger than the giant red stars with size up to 10exp(12) meters [5]). For this small size the beam without light scattering may be bent by gravitational lensing but as a whole (the right and left parts of the beam are experiencing the same path and the same time delay both Shapiro effect and geometrical).



Due to the presence of microlensing the real image of the supernova at Z=1 and beyond would be consisting of many very small dots (provided the resolution of the telescope is 100 times better than Hubble). This is because the smaller masses (compare to strong gravitational lensing which generates visible Einstein cross) will generate many Einstein crosses but they all blurred together due to lack of the resolution. Interestingly the time dilation may be actually observed even in the case of the absence of light scattering and absence of Big Bang (no Doppler-like effect is necessary) – because the already observed Einstein crosses are demonstrating huge difference in time of arrival of light for 4 different images (up to 180 days) and possibly smaller, hardly resolved Einstein crosses will give the time difference comparable to the observed time broadening of the supernova light curves (if Einstein cross is not resolved, all four images will give actually one but photons from different paths arrive at different time, the observed light curve is actually of sum of 4 light curves time shifted with respect to each other – it will inevitably be time broadened).

               In [6] the excellent example of hardly resolved Einstein cross is shown with lensing galaxy much weaker than the supernova images:



If the resolution of the telescope would be just a little worse, this supernova would looks like one image. But it would be actually consisting of 4 overlapped images with different times of arrival and thus the observed light curve would be much broader than each of the constituents. One of the explanations of the supernovas huge visible angular sizes [7] (up to 6 times larger than diffraction limit of the telescope at z=3 as observed by JWST) which preserves the Big Bang is exactly this one – the real image is merely the superposition of multiple Einstein crosses due to weak gravitational lensing (unresolved because the  resolution of JWST is limited). In this case however the time broadening of light curves (seemingly confirming Big Bang due to Doppler like effect) must be even more pronounced – first because of Doppler effect (proportional to 1+Z) and second due to overlapping of different images which have different paths and Shapiro effects (proportional roughly to sqrt(Z)) – in total the time broadening of light curves would be so big that the supernovas already at z=3-4 would shine for many months. Such enormously large time dilation may be already dismissed – even preliminary images of JWST (for z~3) made with time separation of months are not showing such ultra-persistent supernovas.

               The last effect which may contribute the most (Shapiro effect is of course present but usually considered as being around 10% of the time delay due to elongated path) is the different brightness of the different constituents of unresolved Einstein cross. Indeed, this is easy to see on the picture above – no Einstein cross is ideal, usually one component is very bright and one is very dim. If the Einstein cross is unresolved, this may contribute strongly to the observed time broadening of the supernova making it very broad or very narrow (almost as narrow as without any gravitational lensing effect). It also is different for different wavelengths, making matter even more complicated. The great review on this topic is [8] where the effects of microlensing for supernovas at z~1 were estimated as leading to around 10-14 days difference in time broadening (actually enough to explain the “time dilation” for supernovas even without any Doppler-like effect).



This effect is mainly contributing to big scatter of the observed time dilations and should be averaged on multiple observations of supernovae. Unfortunately to make such a statistics even at z~1 thousands of supernovae are to be recorded with light curves (unbearable task even for Hubble plus Earth based telescopes). And for JWST so far only observations of the supernovae are made (and no reported light curve is measured).  Meanwhile this effect by accident may generate extremely broad in time light curve for supernova, seemingly confirming Big Bang, but in another accident may completely reject Doppler-like effect – the scattering of data may be big. Published data on light curves indeed confirmed the big scattering in observed “time dilations” for supernovae at z~1, but whether it is due to such brightness difference mechanism (of unresolved Einstein crosses) or due to inevitable experimental errors is not clear at this time.

Conclusion.

While the initial estimation of the time broadening of the light curve of supernova gave a smaller than necessary value (4.4 days instead of 20 [1]) if other effects are taken into consideration the tired light hypothesis may create big enough value. As it is a typical case in many complex scientific issues, only direct experiment may differentiate the Big Band and Tired Light in the question of “time dilation”. Big Bang and Doppler-like effect must generate at least 1+z time broadening (or may be even larger if microlensing and unresolved Einstein crosses are taken into the consideration), while Tired Light must generate much modest time broadening approximately like sqrt(z) (for more precise formula see [9]). Already for z~3-4 (actual supernovae observed by JWST in 2023-2024) the difference is huge and even with discussed brightness-generated errors should be easy to differentiate. This experiment (direct measurement of light curves for supernovae at z~3-4) may be considered as one of the simplest and possible at the present time (beginning of the 21st century) ways to New Physics (for more proposals see [10-11]).
