If you exceed the speed of light, can you change what happened in the past?

It can't be that things have happened even if you change the past more than the speed of light.

Your original universe is also divided into two parallel universes that do not intersect with each other.

One is what you change and one is what you want to change.

Parallel Universe Theory).

As long as the speed of light is exceeded, time can be reversed, according to the old love of relativity, no object can exceed the speed of light, so human beings want to go back in time due to the limitation of speed is not feasible, but to a certain extent to make time go slower, as for the black hole its huge gravitational pull can make space bend, I think human beings can go back to the past through space conversion

No. You're getting time and space wrong, and it's better to read more books about it, and that's not going to be possible unless you're going to four-dimensional space.

Speed just has the effect of reversing time visually, and it doesn't seem to have much to do with the essence of time, because we live in a three-dimensional space.

Definitely not, the current time still can't be changed, unless the future high-tech invents the "time shuttle"!

Theoretically, when traveling faster than the speed of light, it is possible to return to the starting point the day before, so it can theoretically be changed.

Comrade WSKNFL, we seem to be living in a four-dimensional space.

According to"The speed of light does not change in a vacuum"Principle, in a vacuum or in air you don't want to go back to the past.

However, the speed of light slows down in water or other translucent media, and you may be able to go back in time.

It is still recommended that you read "The Theory of Relativity" in both narrow and broad senses.

Can you really go back in time faster than the speed of light? Can history be changed?

It's hard to say for sure what the future holds.

Can you listen to a song backwards when you're chasing a sound at twice the speed of sound.

If we could go faster than the speed of light, would we really be able to go back in time?

I think there's going to be a space-time reversal, and then we'll be able to travel freely between planes.

I think it's possible to go back in time, because if the speed was faster than the speed of light, then we could have driven a spaceship through the past.

Step back in time. Because according to the theory of relativity, if the speed exceeds the speed of light, you will turn back time. Because faster-than-light allows you to go back in time, it is theoretically possible to go back in time.

It is theoretically possible to travel back in time, but so far there is no speed that can exceed the speed of light.

Go back in time. Because according to the theory of relativity, it is possible to turn back time by exceeding the speed of light, so if we can go beyond the speed of light, we can go back in time.

It's impossible to achieve, whether it's going back in time or seeing the past, and it has nothing to do with going faster than the speed of light.

I think we can see the past, but this is still an assumption, and what it looks like will be studied slowly in the future.

I feel like humanity can go back in time.

If humans were to go faster than the speed of light, would they really be able to go back in time? Einstein's words speak for themselves.

If the speed exceeds the speed of light, it is possible for people to go back in time, which is just a new kind of conclusive theory put forward by scientists in the last decade, whether the hypothesis and conjecture are now true, and there is no concrete scientific research to prove it.

1. What happens when the speed exceeds the speed of light

We have always known that our three-dimensional world is composed of such basic elements as length, width and height, but there is no time, we have been thinking, if we can go back to the past, what kind of conditions need to be achieved, including major film and television dramas, and have always been acting through, generally speaking, some wonderful light spots will occur when crossing in film and television dramas, which does have a certain relationship with light, theoretically speaking, if the speed of light is exceeded, we may catch up with time. If we catch up with the time, will it be possible? Turn back the clock.

Second, whether it is possible to turn back time

This is currently inconclusive, because we have been doing experiments, and the fastest speed we know is the speed that light can reach, that is, the speed of light, theoretically, if we reach the speed of light, then we can control time, but the latest research has not yet developed an object that can exceed the speed of light, or a science. It helps us control time and even rewind time. Of course, we also have to think about how we transport ourselves back to the past, even after we have gone back in time, and what kind of form we are in after returning to the past.

3. What conditions need to be met to go back to the past, or what kind of questions should be considered?

Going back to the past is not simply a whole person returning to the past time and space, but whether it will cause chaos in the cosmic order after we complete such a science, first of all, we make a hypothesis that has been completed and can transport people back to the past, so is it a single person to go back to the past, or is the whole time and space reversing everything about this person back to the past? Whether such a science is completed or not, the whole world will become upside down. If this is the case, this is a scientific paradox, and theoretically, even if humans exceed the speed of light, it is still unknown whether they can go back to the past, and it is very likely that they will not.

I don't think so. Because time cannot be turned back, the past time can never be returned, the wheel of time will only roll forward, even if the speed exceeds the speed of light, there is no way to go back to the past.

No, exceeding the speed of light is only a matter of principle immortality, and going back to the past will not appear.

Speed beyond the speed of light can't go back to the past, time travel is not a thing that doesn't exist at all, at most, you can see what happened before, and you can't intervene.

You walk in all directions, you jump, you move in 3 dimensions.

An attempt to go back in time is an attempt to move backwards on the timeline.

If the speed of the object is closer to the speed of light, the slower the degree of motion of electrons, atoms, neutrons inside the object. If the object is an individual, it can be assumed that the person's aging, metabolism has slowed down--- and time has slowed down in this way. Time is not uniform in the universe, and the course of time is different depending on the speed.

When an object reaches the speed of light, it is beaten into a quantum of light.

There are no objects moving faster than the speed of light, so there will be no objects that exceed the speed of light. -- So you can't go back in time.
