PBS Space Time Season 2023 Episode 19
Overview:
One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the speed of light wasnât different in the past, or perhaps in other parts of the universe? In fact, variable speed of light theories have long been used to try to explain everything from dark energy to gravity itself. Letâs explore how constant this fundamental constant really is.
