Can we go back to the past beyond the speed of light? Space time crossing needs the joint efforts of space and time

With the rapid development of human science and technology, people have more and more understanding of time and space. In recent years, there have been a lot of time travel novels and dramas, which describe that the protagonist inadvertently goes back to the past through time and space and starts a brilliant life with the memory of the future. After reading more of these novels, many people will think, does time travel really exist?

According to Einstein’s theory of relativity, when the speed of an object reaches the speed of light, space and time will lose their meaning, and time will stop. If the speed of an object exceeds the speed of light, does it mean that time can flow backwards? If this theory holds, can human beings go back to the past through time and space? Let’s hear how scientists explain this.

We know that according to Einstein’s theory of relativity, the speed limit of an object is the speed of light. When the speed of an object reaches the speed of light, time and space will be meaningless, and time will stop. No matter how the external time changes, the time of an object at the speed of light is still. For example, when you travel to a planet 100 light-years away in a spaceship at the speed of light, for people on earth, 100 years have passed, but for you, you only feel like a moment has passed and you are not getting old.

The object flying at the speed of light itself is in a static state. Some people have imagined that it means that if we sit in an object flying at the speed of light, as long as we keep flying, we can live forever? There is also a question: if the speed of light can make time stand still, if the speed of an object exceeds the speed of light, can we turn back time and go back to the past?

I wonder if my friends think so? In fact, it’s obviously impossible. If flying faster than light can turn back the clock, will the people inside the spaceship not only not grow old, but also become younger and younger? In fact, it’s impossible. It may exist to travel through time and space and return to the past, but it is obviously not a simple way to surpass the speed of light. There is the concept of time in it.

There are two concepts in the universe that are most mysterious and difficult to understand. One is space and the other is time. Fortunately, modern scientists are studying and understanding more and more, but we know nothing about time. What we know about time is only the time defined by human beings, which is not the essence of time at all. What is the real time? There’s no way to start. It’s more complicated than studying dark matter and dark energy. Time is ten million times more mysterious than space.

What can we do with space? If you master space, you can ignore the limit of distance. The universe is vast and vast. If you don’t have infinite speed, you can’t explore the whole universe at all. The speed of light can only be regarded as the basic speed in the universe, and superluminal speed is the king’s speed. So how to make the speed exceed the speed of light? This requires the concept of space.

The universe looks very smooth and complete, but if you enlarge the universe, you will find that the universe is full of many space cracks, which are space channels. Only by mastering the secrets of space, we can open the space channel in the universe at will, and the spaceship can fly faster than light when it enters. However, superluminal flight only allows you to quickly reach the depths of the universe, and will not make you younger and younger, let alone let you go back to the past through time and space.

Is it impossible to cross time and space? Of course, it is not. If we can master time completely, we can combine space with time. As we said just now, flying beyond the speed of light can only make you travel through the universe quickly. It’s just a voyage in space. But if you want to go back in time, you need to add the concept of time.

Time reversal is an application of time, but time alone can’t travel through time and space, go back to the past and so on. It also needs space to combine, that is, surpass the speed of light. Therefore, if you want to travel through time and space to go back to the past, you also need to open a time channel. In this time channel, the speed exceeds the speed of light, but it does not allow you to travel to a place in the universe. Instead, it combines the application of time to let you navigate in the long river of time. You can see the vicissitudes of history, the scenes of the past, and even a few scenes in this time channel A billion years ago, billions of years ago.

Maybe a lot of people will think that when human beings can master time and space, they will create time machines and we can travel in time. It’s a good idea, but it’s not easy for human beings to master time. To fully master space and realize superluminal flight, it’s conservatively estimated that it will take another 10000 years at the speed of human development. And time is tens of millions of times more complex than space. It may take hundreds of millions of years, billions of years.

I believe that as long as human beings master the concept of time in the future, they will become the top civilization in the universe. Time is the most mysterious thing in the universe. Mastering time may be the God of the universe. Everything in the universe will no longer be a secret. We are looking forward to the arrival of human beings to realize all this.
