How fast the light travel
WebSo, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans. Even for very tiny things, like subatomic particles, the amount of energy ( E ) needed to near the speed of light poses a significant challenge to the feasibility of almost light-speed space travel. Web1 mei 2014 · So how fast is that, exactly? Really, really fast! In terms you might be more familiar with, light travels at about 186,000 miles per second or approximately 671 million miles per hour!
