Is it possible to go so fast you go back in time?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.

What happens if a human moves at the speed of light?

The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which they are traveling.

Is it possible for humans to travel at light speed?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

Does going faster than light lead to backwards time travel?

So, simply going faster than light does not inherently lead to backwards time travel. Very specific conditions must be met—and, of course, the speed of light remains the maximum speed of anything with mass.

Can anything travel faster than the speed of light?

Nothing can travel faster than the speed of light. But if it could, the conventional wisdom goes, it would travel back in time. Is the conventional wisdom right?

Can particles travel faster than light through walls?

Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls. The bizarre rules of quantum mechanics allow a particle to occasionally pass through a seemingly impenetrable barrier.

What happens when a spaceship goes at the speed of light?

When the spaceship goes exactly at the speed of light, from the point of view of the observer back on Earth, everything appears normal as the ship speeds away.
