Physics: light can move infinitely quickly during the Big Bang

Физики: свет мог двигаться бесконечно быстро во время Большого Взрыва

. Fluctuations in the microwave “echo” of the Big Bang indicate that the speed of light was much higher in the first days of life the Universe than today and that it reached endless values at the time of her birth, state physics in an article published in the journal Physical Review D.

“Theory of the intermittent speed of light has now reached a certain point of maturity that allows us to test it in practice. If the observation of microwave background radiation of the Universe shows that the calculated number is accurate, then we have to change the theory of gravitation of Einstein. All this will mean that the laws of physics then and now are markedly different,” says Joao Magueijo (Joao Magueijo) from Imperial College London (UK).

In accordance with the theory of relativity, light and other electromagnetic radiation move through a vacuum at a constant rate, equal to 300 thousand kilometers per second and not exceeding this value in other environments. This postulate is the cornerstone of modern physics, on which all our current ideas about the Universe and its behavior.

About 15 years ago Magueijo and a number of physicists from the so-called Perimeter Institute in Canada, focused on the search of “unorthodox” theories, formulated a new theory of relativity, which explained the number of inconsistencies in the description of the Big Bang and thus postulated that the speed of light would be different in the first moments of the existence of the universe.

Naturally, such a theory has been extremely negatively met by most physicists, who considered it more incorrect than the calculations of Einstein. Magueijo and his colleague Niayesh Afshordi (Niayesh Afshordi) from the Perimeter Institute figured out how to test this idea, drawing attention to the special structure of “echo” of the Big Bang – the so-called microwave background radiation of the Universe.

The first observations of this radiation were carried out using probes WMAP and “Planck” showed that it has a sufficiently large anisotropy, for example, the famous “cold spot” in the constellation of Eridanus, which is beyond the limit for quantum fluctuations of the vacuum and other things predicted by modern physical theories.

As explained Magueijo, the ratio of these large and small inhomogeneities, the so-called spectral index, it is difficult to predict with the help of modern cosmological theories, so scientists had to come up with the idea that the universe initially expanded very rapidly and then the rate of growth slowed sharply and fell to contemporary values. The new observations show that this acceleration and deceleration could occur at least seven times, what makes scientists doubt the veracity of modern cosmology.

How could this happen and why is it “inflationary field” as a driving factor of this process, scientists have ceased to exist, yet no one can explain. Magueijo and Afshordi found a way to abandon this “unnecessary entities”, suggesting that the speed of light would be different in the Big Bang.

Their calculations show that in the case where the speed of light was infinite at the Big Bang and significantly exceeded the current value in the first moments of the Universe, the ratio of large and small inhomogeneities in the microwave background radiation is equal to that observed and “plank”, and WMAP – about 0,96478.

The accuracy of these observations, as noted Magueijo was rather low, the scientists were able to confirm this figure only up to the third decimal place. However, in the next few years the sensitivity of the instruments will reach the values needed to test this hypothesis and its confirmation or refutation, conclude the authors.
