Scientists have managed to find a way to test the theory that the speed of light in the universe in the early stages of its existence could be slightly higher than at present. This hypothesis belongs to the Portuguese cosmologist and physicist João Mageiju. His work has been published in the specialized edition Physical Review.
According to the scientist, her assumption can be verified. Galaxies, according to modern scientific research, were formed as a result of quantum oscillations that existed in the first seconds of the formation of the universe. In the cosmic microwave background (also known as relict radiation), you can still find traces of fluctuations in the density of matter as a spectral index characterizing changes in the spectral density of radiation as a result of frequency changes.
In his hypothesis, the scientist relied on the theory that the speed of light affects the spectral index. Thus, the physicist assumed that its value is 0.96478. In the event that further research confirms this value, then Mageiju's theory can be considered correct.
According to his assumptions, during the beginning of the expansion of the universe, the speed of light was high enough, but then, as a result of the decrease in the density of space, it fell.
There is an alternative to the Mageiju hypothesis - this is the theory of inflation, generally accepted in the scientific world, according to which the speed of light in the Universe was initially small, but later increased sharply. Both theories can explain the same density of the Universe, but at the same time, Mageijou's theory is much easier to test.
