Modern science tends to believe that the speed of light has always been the same. Now, scientists assume that the seemingly constant constant could change over time, and they found a way to check whether this assumption is true. The method by which you can check the changes in the speed of light, developed by professors Joao Maguejo and Nyaesh Afshordi from Imperial College London.
Using relic radiation, they calculated fluctuations in the radiation density of the early Universe and gave it an accurate spectral index based on the theory that the light was much faster in the first seconds after the Big Bang (by 0.96478). If the further calculation of the index coincides with this number, then this will prove the assumption about the changed speed of light.
Assumptions are not based on sheer enthusiasm. Existing calculations suggest an index of 0.968, which is very close to the assumptions of scientists who believe that the speed of light has changed. However, the current challenge is to collect high-precision data so that you can talk about any conclusions. And there is no guarantee that everything will eventually work out either.
If the concept of a variable speed of light proves its viability, it will change our understanding of how the Universe has expanded. Now the theory of constant speed does not give answers to the question of how light had enough time to get to all corners of the Universe, even taking into account all the energy that it has. The presence of ultrafast light could fill this gap and force scientists to reconsider some aspects of the existence of the early Universe.
And even if in the end it turns out that the light always moved at the same speed, the probability of the theory of variability of its speed gives additional weight to the theory of inflation, according to which the Universe after the Big Bang expanded almost instantly.
