As long as the speed of light is removed, you can turn back the clock

According to Einstein's theory of relativity, time slows down when moving at a speed close to the speed of light. That is, when moving at the speed of light, time stops in the eyes of a relatively stationary person. So some people come to the conclusion from this that when moving faster than the speed of light, time goes backwards.

However, we need to be clear about the meaning of the word "relative" in the "theory of relativity", that is, we can "see" the "past" of objects moving faster than the speed of light, but it does not mean that we can go back to the past.

The highest way for people to record events is to use light, and when the speed exceeds the speed of light, we can't go back in time, but we can see the past.

If the speed of light is eliminated, the speed is always there, and what we lose is only a standard, and the essence does not change.

Personally, I think that time can be turned back, and as we all know, the way we see ourselves in the mirror is a synchronous reflection of light. So can we think that if there is a "mirror" that can reflect energy faster than the speed of light, then we can see what has appeared in this mirror before? These words are understandable, right?

As for what actually appeared in the past, then I can't understand it. Maybe we can see the past, but we can't change history.

My understanding is impossible!

Even if the speed of light is eliminated, I think it will be possible to freeze time at most! It's impossible to go backwards, it's just a fantasy!!

A speed greater than or equal to the speed of light should be considered a success, but if a person reaches that speed, he will be torn apart!

My understanding is that when we reach the speed of light, we can catch up with the light that passed us in the previous moment, so our vision can stay in that moment. The same can be seen at the speed of light. But light does not seem to be a medium to carry information, so it can only be seen, not experienced.

Probably not, I read a report that French scientists successfully reduced the speed of light to 6m s, so I don't think the speed of light is directly linked to time.

Many researchers agree that you can't go back in time. There is a famous paradox, if you go back in time and kill your young, unmarried grandfather, there will be no you in the future, but this is not the case, there is only one conclusion, you can't go back in time.

Moreover, even if you go back to the so-called past, it will not be the past of our universe, it may be another universe parallel to ours.

Not really! The saying should be: speed is greater than the speed of light, and time can be turned back.

But the speed of light propagation in a vacuum is constant, i.e., no object can reach a speed that exceeds the speed of light.

Speed is just a benchmark

I believe! I'm also a sci-fi fan.

This sentence has very little credibility, after all, the past has passed and cannot be changed, all we can change is the past and the future, and he may be based on the theory of relativity

Faster than the speed of light, you can see the past.

With the continuous development of social economy, in our lives, many people are very curious about many scientific issues, especially many friends want to know whether the speed of light can turn back time, in fact, according to the relevant scientific explanations, the speed of light may allow us to travel to the future, but it is absolutely impossible to turn back time, because this is contrary to the development of many scientific foundations, and also violates the basic theories of many sciences, and even from the moral point of view is unreasonable.

First of all, we have to understand a problem, the speed of light is only a thing that we can theoretically get, but in fact, our current science, and our current technology, can not reach the speed of light at all, if we can't reach the speed of light, each of us can not know whether the speed of light can make time go backwards, and not only that, because if the speed of light is really too fast and becomes light, then it will also transcend time and space, beyond time, so where is the saying that time goes back? So we can't really be conclusive about it.

With the continuous development of science and technology, the reason why many scientists will put forward this woman is because science should derive an idea based on relevant conclusions, and this idea is a result of combining time in the special theory of relativity with the speed of motion of objects, so we can turn back time from the speed of light, this kind of thing stays on the formula, unless human science and technology can really develop to the point of the speed of light, it is difficult to turn back time. It is impossible to say that time is so easily turned back by us.

To sum up, we can obviously know that the speed of light cannot turn back time, and this is completely just a theoretical thing, of course, most scientists believe that the speed of light can make time go backwards, which we cannot deny, because our own ability has not reached the level of scientists, but we believe that practice is the only criterion for testing theories.

The speed of light can't turn back time, it can only make time move forward, and the speed of light is really fast.

Theoretically, it is possible, but this is not possible at the moment, and some scientists are still working on this aspect.

Of course not, because the speed of light is only a unit of speed, so it has nothing to do with time.

It's impossible, because time passes by, and it's impossible to turn back time at the speed of light, which is a particularly immature idea.
