Einstein's math still works out
Nothing we know of zips along more quickly than light. Einstein, nearly
100 years ago, said it's not possible. For us, the speed limit makes
strange sense: Go faster than light, and you could return before you've
left, become your own grandpa, or other perform other leaps of cosmic
logic.
In a study, ultra high-energy cosmic rays thought to originate in a collision of galaxy clusters are slamming into Earth's atmosphere at more than 99.9 percent of the speed of light. Measurements put the number at 99.9 followed by 19 more nines -- about as close to light-speed as you can get without splitting hairs.
