The laws of physics aren't 100% - they don't seamlessly cover everything, and develop serious errors in extreme situations. Physicists know this, which is why they're searching for a Grand Unified Theory which doesn't have this problem. Note that all of the examples involve the impossible (rotating the universe), the infinite (and infinitely big ____), or wormholes (which have never even once been observed and we have no proof they even exist at all).there are no laws of physics ruling out the possibility of time travel
Finally, even if time travel is possible, it didn't happen to this guy's buddy. If it had, he'd have more to show for it than a bunch of faked dinosaur photos.
Yes, yes they would.I'm by far a scientist from NASA, but wouldn't two moons, that close to the earth flood the entire planet twice a day from the tides? Life forms with lungs can only drown once a day comfortablly.
Headquarters? Since when do scientists have headquarters?Because scientists are safely tucked away in their headquarters while Johnny Joe from the Trailer Park is working a dead-end job on his night shift outside a power plant quietly tucked next to a forest.
Wrong. In your thought-experiment, nobody travels *back*, they just travel forward at different rates. No dinosaurs.It is 100 percent possible to go back in time, and I shall explain how.
The speed of light *in a vacuum* is constant and the limit, but light can be slowed down or sped up in certain media (cesium gas, for example) because it "jumps" (called quantum tunneling) instantly from one point to the next, effectively 'cheating'. Without any way of 'jumping' (which, by the way, cannot work for anything bigger than an electron), light is limited to c, 3 x 10^8 m/s.although today we have lasers that actually do travel faster than light so I'm not sure how this theory is still holding true...
