List Of Is There Time At The Speed Of Light Ideas. Why does time change when traveling close to the speed of light? Web one final point worth mentioning is a hypothetical idea put forth called variable speed of light (vsl) cosmology, which suggests that the speed of light itself has changed over time.

This is an extremely controversial theory and there's little direct experimental evidence to support it. The speed of light is the fastest speed in the universe, and it is always a constant in a vacuum. Hence, the speed of light is 299,792,458 m/s.
