The theory that the speed of light when the universe was just formed much higher than today could alter Albert Einstein’s theory of relativity.
John Magueijo, a professor at Imperial College London, UK, and Niayesh Afshordi, PhD at the Perimeter Institute, Canada, proposed the idea that the speed of light when the universe was just formed much higher than at present, and the correctness of this theory can be tested, according to Phys.org.Previously, the physicist Albert Einstein said that the speed of light is always constant in every situation no different space and time. Assuming the speed of light is constant (equal to 299,792,458 m / s) and create preconditions for building many important physical theories such as relativity and Einstein’s general model of the early universe declared after the Big Bang.
Scientists previously believed that only a few seconds after the Big Bang, the universe expanded rapidly from a single point in the process of enlargement. But if the light moves at a constant speed, the photon will not have enough time to go to the limit of the universe observed. Scientists call this “horizon problem“.
To solve these problems, the researchers hypothesized speed of light is changed at the time of the early universe, moving faster in some areas. If this is true, it will leave its mark in the cosmic background radiation (CMB) left over from the Big Bang, as the spectral index (spectral index).
Magueijo and Afshordi use computational models to give exact figures on the spectral index of 0.96478. This figure is quite close to the current estimate, about 0.968 with errors. The study results are published in the journal Physical Review D 18/11 day.
“The theory that we propose for the first time in the late 1990s was complete and verifiable. If future observations confirm this figure is correct, Einstein’s relativity will no longer true and natural laws are not always the same as today, “said Magueijo.
