Albert Einstein, the Father of Modern Physics, is one of the greatest minds of all time. Many scientists spend a lifetime trying to prove his theories. His theory of relativity, which suggests that light travels at a constant pace, is a cornerstone of physics. However, some physicists say that Einstein could be wrong, and that the speed of light is not constant.
The problem with the horizon is generally explained by inflation, meaning, the universe's temperature had become more consistent after the Big Bang, but before it had quickly expanded substantially. Many scientists question whether inflation serves as a valid solution to the conundrum - which suggests that had a constant temperature before photons moving at a constant speed had a chance to cover the universe as it expands.
After The Big Bang, Light Travelled Faster In Some Regions
Professor Magueijo and Dr Niayesh Afshordi from the Perimeter Institute in Canada may have found proof that after the Big Bang, travelled much faster in some regions than in others. They believe that the violent events of the Big Bang resulted in fluctuating variations of density, which were powered by varying speeds of light.
The Idea Was First Proposed Two Decades Ago
In 1998, Magueijo and Niayesh first suggested that the speed of light may have been faster. "The theory, which we first proposed in the late-1990s, has now reached a maturity point - it has produced a testable prediction. If observations in the near future do find this number to be accurate, it could lead to a modification of Einstein's theory of gravity," Professor Magueijo said.
If the study is proves that photons were indeed faster-moving than gravity, it would mean that that would have allowed them to cover the universe in its entirety, and help it reach a balanced, uniform temperature.
