I have explained that we can't exist (the past and future will collapse) if there could exist an absolute truth...
iamnotback you have not made the case that an absolute truth cannot exist though perhaps you made this argument somewhere I am not aware of. In your essay
you instead made this claim.
There are a minority of scientists who believe that this is the exact the condition of the universe at the start of the big bang.
But in the late 1990s, a handful of physicists challenged one of the fundamental assumptions underlying Einstein’s theory of special relativity: Instead of the speed of light being constant, they proposed that light was faster in the early universe than it is now.
This theory of the variable speed of light was—and still is—controversial. But according to a new paper published in November in the physics journal Physical Review D, it could be experimentally tested in the near future. If the experiments validate the theory, it means that the laws of nature weren’t always the same as what we experience today and would require a serious revision of Einstein’s theory of gravity.
"The whole of physics is predicated on the constancy of the speed of light."

So just how much faster was light speed just after the Big Bang? According to Magueijo and his colleague Niayesh Afshordi, an associate professor of physics and astronomy at the University of Waterloo, the answer is
“infinitely” faster.The duo cite light speed as being at least 32 orders of magnitude faster than its currently accepted speed of 300 million meters per second—this is merely the lower bounds of the faster light speed, however.
As you get closer to the Big Bang, the speed of light approaches infinity.
On this view, the speed of light was faster because the universe was incredibly hot at the beginning. According to Afshordi, their theory requires that the early universe was at least a toasty 10
28 degrees Celsius (to put this in perspective, the highest temperature we are capable of realizing on Earth is about 10
16 degrees Celsius, a full 12 orders of magnitude cooler).
As the universe expanded and cooled below this temperature, light underwent a phase shift—much like liquid water changes into ice once the temperature reaches a certain threshold—and arrived at the speed we know today: 300 million meters per second. Just like ice won’t get more "icy" the colder the temperature gets, the speed of light has not been slowing down since it reached 300 million meters per second.
If Magueijo and Afshordi’s theory of variable light speed is correct, then the speed of light decreased in a predictable way—which means with sensitive enough instruments, this light speed decay can be measured.
"Varying speed of light is going back to the foundations of physics and saying perhaps there are things beyond relativity."

Now that they’ve used the variable light speed theory to put a hard number on the spectral index, all that remains to be seen is whether increasingly sensitive experiments probing the CMB and distribution of galaxies will verify or overturn their theory. Both Magueijo and Afshordi expect these results to be available at some point in the decade. But Marsh and other physicists aren't so sure.
If their theory is correct, it will overturn one of the main axiom’s underlying Einstein’s theory of special relativity and force physicists to reconsider the nature of gravity. According to Afshordi, however, it is more or less accepted in the physics community that Einstein’s theory of gravity cannot be the whole story
