Answer:
Technically, the speed of light is not infinite. But passing the speed of light means that you would travel backwards in time.
Explanation:
So, if the speed of light is infinite, then the years that passed will get brighter and brighter. So ancient times would be burned to crisp while the future would be dim. The concept here is that light dims as the farther you travel forward in time. That is because all the light is past the speed of light, so they travel backwards in time.
