Was Einstein Wrong About The Speed of Light?
New theory could completely change our view of the universe
Albert Einstein believed the speed of light was constant in a vacuum
This constant has formed the basis of many theories in modern physics
But the model of inflation leaves a conundrum called the Horizon Problem
Physicists believe that light may have travelled faster in the early universe, before slowing to present levels, which could be tested with observations

At the heart of Einstein’s theory of relativity is the idea that light travels through the vacuum of space at a constant speed.
It has been used to work out the age of the universe, and gives cosmologists an idea what happened just after the Big Bang.
