Does it really turn back time when a person reaches a certain speed

First of all, according to Einstein's theory of relativity, only the speed of electromagnetic waves can reach the speed of light, while the speed of other objects can only be infinitely close to the speed of light and cannot be reached. Furthermore, if we have a release event on our planet"a", then A will be launched at the speed of light outside the Earth, and if this happened before, if you want to see it, you have to get on a spaceship that is faster than the speed of light to chase after Armor and overtake it, and look back at it. And, even then, you're just"See"It's not"Turn back in time.

Actually, the so-called"Time"It's just a yardstick that we use to show the order of events, and it can only be"Shun"happens.

You won't reach the speed (speed of light) that turns back time, because you can increase the speed when you accelerate, and the higher the speed, the higher the energy you need to accelerate according to the special theory of relativity, and the energy to accelerate to the speed of light is positively infinite, so causality is maintained, the theory is self-consistent, and it will not exceed the speed of light.

No. It's just that time is slowing down.

Maybe one second of yours is equivalent to 10 seconds of someone else.

This is what Einstein's theory of relativity says. But there is one question he hasn't thought clearly, even if he really wants to reach or exceed the speed of light, he can turn back time, so what state does a person exist in? Can it still maintain its own flesh and blood, or has it become a particle or a ......?

No matter how fast it is, you won't feel any change in your time, and the watch you're carrying will feel like he's going slower!

No, his theory has limitations.

Relative to what nature of the frame of reference.

Summary. Dear, I'm glad to answer for you.

Dear, I'm glad to answer for you.

Is it possible to rewind time? You can't turn back time, you can't do it. Time reversal generally refers to a closed time-like curve in the theory of relativity, given a four-dimensional space, the distance between two points in the coordinate system is 0, and in Euclidean space, the two points with a distance of 0 coincide, but in four-dimensional space, it is generally believed that there is a time axis, that is, the two points coincide in space, but there is still a time distance.

Hello, I'm honored to answer for you, the answer is no, "time reversal can't be achieved." Time reversal generally refers to a closed time-like curve in the theory of relativity, given a four-dimensional space, the distance between two points in the coordinate system is 0, in Euclidean space, the distance of two points coincides with 0, but in four-dimensional space, it is generally believed that there is a time axis, that is, these two points coincide in space, but there is still a time distance. That is, two different times at the same point, at this time, a new space similar to a cone will be formed in the coordinate system, commonly known as it"Light cones", i.e. two points that coincide in space can be transferred in time if we are in"Light cones"Within, it is called"class"and vice versa"Class null"。
