Nov 13, 2017. In a vacuum, light travels at a mind-bending 300,000 kilometres per second. That's not just very fast, it's as fast as it is physically possible for.

It’s critical that you realize that there are two types of time travel, and they are radically different. Time travel to the future? Definitely possible. go out into space and travel near the speed.

You cannot talk about the speed of light without defining your frame of reference. The measured speed of light in local inertial frames is 299792.458 km/sec. So if you want to make a comparison with "299792.458 km/sec" then you have to make it in a "local inertial frame". Special Relativity requires the frame of reference to be inertial (travel in a straight line).
