Super-Fast Space Travel Would Kill You in Minutes
Everyone thinks it would be cool to travel at the speed of light, which is why scientists devote their lives to working out if it would be possible and NASA is trying to develop its own warp drive. But easy, tiger: turns out super-fast space travel would be fatal. A paper published in Natural Science brings some boring common sense to the speed-of-light-travel table.
In order to travel huge distances in next to no time, people need to travel close to the speed of light. In so doing, travelers cover extremely large distances very quickly and, thanks to the quirks of relativity, would feel like it took mere minutes because of an effect known as time dilation, which squashes perceived time. Trouble is, traveling close to the speed of light brings about other effects, too. The researchers point out that hydrogen in any craft cable of traveling at the speed of light would also prevent it from traveling at the speed of light.
