Introduction
In 2025 a group of theorists claimed the evidence for acceleration of the universe via dark energy in the SN1a data didn’t stand up to scrutiny. Their research suggested that the expansion of the universe might no longer be speeding up and offered a different mathematical solution to the apparent “acceleration” problem first mooted by Reiss and others a few decades ago. However an even more recent paper (Still accelerating: type Ia supernova cosmology is robust to host galaxy age evolution. Wiseman, Reiss et al 2026.) with authors including Reiss, one of the the original proponents of imaginary acceleration, argued this 2025 paper refuting acceleration was based on an incorrect analysis.
Separate to this It’s amazing how critics say that any paper that doesn’t supply enough “maths” does not contain acceptable levels of theoretical ‘proof’ to publish. Yet these same maths obsessed theorists will ignore the fact that endless “acceptable” peer reviewed published papers with pages and pages of maths and formulae will end up being subsequently rejected as erroneous and not acceptable as theoretically acceptable anyways. Despite having initially claimed having so much maths in these papers confers proof. (Proven as they prefer to say). Probably 99 % of these math riddled papers proving various erroneous now rejected concepts and published in the last century have been subsequent rejected as nonsense theory by the same establishment theorists who claim that endless pages of maths confers instant acceptabilty for publication regardless of how ridiculous the theoretical concept proposed in the paper actually is. Give a theoretical physicist an orange and with enough pages of maths, he can claim it’s actually an apple.
Anyways to get back to this tit for tat about the imaginary Big Bang acceleration debate: Its worth pointing out that in fact despite endless fiddling of the evidence with maths, the acceleration and expansion problem is theoretically unsound as the acceleration first mooted by those theorists including Reiss in the 90’s is ignored the fact that the SN1a data sourced from the SCP actually shows no expansion at all! As shown by the analysis in this chi squared maths page.
And so the apparent acceleration claimed by Reiss and others was an attempt to try and explain why the non expanding data seemed to fit less and less well with data from ever higher and higher redshifted SN2a data in the BBT expanding model.
Summary
Essentially the SN1a data is not time dilated at all. As this analysis shows. Fortunately for theorists, it turned out that at low redshifts and with arbitrary tweaking of the luminosities of the Hubble Space Telescope SN1a data a fit of sorts to an expanding model was possible. Although as this analysis shows the theorists forgot to control test the data with a z=0 chi square fitted model. If they had done this as the cited analysis shows, they would have found that the SN1a data fits as well and better to a non expanding model than to any expanding BBT model. And so when even higher redshifted data was fitted to their expanding model by theorists it failed to show the expected increased time dilation at these ever higher redshifts, as can be expected seeing as the universe isn’t expanding at all.
To account for this increasing lack of any observed time dilation at all in the very high redshifted data, theorists like Reiss and Wiseman pretend that the extra dilated time dilated lightcurve is still there but it’s just too faint to be seen! And they argue that the reason why they think the very hi redshifted dilated lightcurve is still there but can’t be seen is because an Accelerated expansion has placed them even farther away from our telescopes then originally expected in their original imaginary BBT model and therefore made them appear fainter than expected than in their original non accelerating BBT model
What flights of fantasy these maths obsessed theoretical physicists resort to to cover up the fact that astronomical observations of our non expanding universe continue to refute the BBT.
