Can anyone tell me if the speed of light in a vacuum was the same a few seconds after the big bang when the universe was small as it is today? In other words could it be that the speed of light changes as the universe expands?
Also is it actually known why light travels at the speed it does? If not then there is no point in me asking what is so special about that speed at which it travels with no varience.
