Can you reverse time if you go faster than light?

This was accepted in classical physics, and the special theory of relativity took pains to preserve the rule, despite the relativity of an object’s motion. But if something can travel faster than light, it can travel backward in time, according to the theory.

Is backward time travel possible?

As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.

Can we travel past light speed?

The fact is we’ll never be able to travel beyond the speed of light, at least based on our current understanding of established physics. As any object with mass accelerates – like a proton in the LHC – it gains energy, always needing just a little bit more energy to accelerate even further.

Why does going faster than light make you go back in time?

The special thing about relativity is that everyone measures the speed of light to be the same. Because light travels at 45 degrees, anything traveling slower than light from this t=0 event is closer to the time axis than the light rays, and anything faster than light is further away from the time axis.

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.

Why can’t anything travel faster than the speed of light?

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

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.

Can you travel back in time with a faster speed?

Going faster than the speed of light doesn’t make you travel back in time, but you can arrange things so that backwards travel is possible. The easiest way to understand this is by considering what’s been called the Andromeda paradox.
