What is it like to travel in a time machine?

Time travel is a science fiction activity in which a person leaves the present and places himself in the future or past. Time travel is one of the most exciting ideas in science fiction. Boarding the time machine, a person can use the control system to determine any date (past or future), and then the time machine can transport him or her to that era in an instant.

In a time machine, a person's age is the same as when they entered the machine. Scientists believe that time travel cannot become a reality, after all, we have not yet seen visitors from the future riding a time machine.

Time travel really exists, but human beings can't do time travel, it is conceivable that the reason why we have not met future people in reality is that human science has not advanced to the point of time travel and perished for unknown reasons, perhaps there is no intelligent creature in the universe whose technological level can reach the point of time travel, after all, time travel has really been achieved, and the universe will almost be controlled by human beings. Taking a step back, human technology has reached the point where human technology can travel time and come to the time and space where we are, but the time traveler cannot interfere with anything that happens in our time and space, and cannot even communicate with anyone, because in this time and space, the traveler may change history as long as he intersects with the outside world, so even if he comes to our time and space, we have no way of knowing, and we will not know.

If you want to travel back in time, you must teleport back to a time portal at the same time, otherwise it is impossible to return. Wait, can you travel back to history and back to the future? Does it make sense in physics?

If you can't come back, is there really anyone who wants to go back to history? When the time machine is returned, the power supply and other supporting equipment must be transmitted at the same time. Brain make up, if you need a lot of energy (definitely not a small amount of energy, it's going to be faster than the speed of light), do you need to teleport a nuclear power plant back?

So, it may be that no one wants to go back to our backward era, it's not that people don't have the ability to come back.

Very interesting, I first returned to the Warring States Period, saw the tragedy of the war of the nations, and then I went to the Three Kingdoms Period, and saw Zhuge Liang fighting the Confucianism on the tongue, and then I came to the Tang Dynasty, and I was proud of the prosperity of the Tang Dynasty.

It is possible that humans have indeed mastered the technology of time travel, but due to the law of cause and effect and the butterfly effect, the teleported objects disappear instantly. The logic is as follows: once the object that travels back from the future interacts with the current matter, even if it is the effect of atoms, quarks, and super-dazzling scales, it will be infinitely amplified through the butterfly effect, which will completely change history, and the new future will be completely different from the old future, and those objects that should have traveled back will no longer exist, so once the object travels back, it will disappear immediately, and it is too late for anyone to perceive it.

In my dream, I traveled to the earth tens of thousands of years later, everything on the earth has changed greatly, people no longer use things like mobile phones, instead of mini touchable displays, cars and airplanes are combined into one, highways have become high-speed passages, and it only takes 1 hour to circle the earth, which is very developed and very convenient.

Now that I go to the sun, I can send a message to the earth in eight minutes, so that people in eight minutes can see me now. If I go to Sirius now, I can send the message to Earth in four years, so that people in four years can see me now. If the distance is farther away, the person who sees me is farther into the future.

It's an amazing feeling. When I was dreaming, I dreamed that I had broken a game disc, and the game disc was split into two pieces, the top and bottom (yes, the top and bottom pieces), and I crossed the separate discs together. The dream is over.

A month or two later, I bought a disc of a pirated version of Gears of War (forgive me for not having the money) and after installing the game, I couldn't play it alive or dead, and a hint was missing something. In a fit of rage, I broke the disc, split it into two, and I crossed it together. After the crossing, I suddenly thought of this scene as if I had dreamed of it, exactly the same as in the dream, and I was covered in a cold sweat.

Let go of me, let go of me! I'm a new human from the year 2130, and I'm here to tell you that there will be a worldwide disaster in the next 30 years, but what are you going to put me in a mental hospital? Haha, just kidding, time travel must be fun.

I also have a friend I haven't seen for ten years, never contacted, all over the world, but always inadvertently dream in my dreams, in the dream we went back to junior high school life, very comfortable and happy, but gradually I don't want to inquire about her recent situation, I know that the beauty I miss only exists in the carefree life of the past, I don't want to let me wake up again through the current situation, let the regret stay in the past with the good, I just have that thought, and then live myself.

Theoretical physics does not study the composition of matter, the composition of matter, the structure of matter, the size of matter, and the subdivision of particle matter, but only focuses on extracting the basic properties of matter, and then understanding all aspects of the universe.

If you can't go back to the past, then you can't go back to the future.
