## Can humans survive light speed?

So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans. … However, even a miniscule proton would require near-infinite energy to actually reach the speed of light, and humans haven’t figured out near-infinite energy quite yet.

## What is the fastest a human has traveled?
