Can you really travel back in time and space to go back in time Be scientific, don t talk nonsense i

It's complicated, let's explain it simply: e=mc*2, Einstein's theory of relativity mentions that our world space belongs to the four-dimensional space. The meaning of four-dimensional space is that time and space are connected, that is, time and space are unified.

The four-dimensional space-time is not limited to this, from the relationship between mass and energy, mass and energy are actually the same thing, mass (or energy) is not independent, but related to the state of motion, such as the greater the velocity, the greater the mass. For example, if two identical clocks, one on Earth and one on a high-speed space shuttle, land on the plane and find that the clock on the plane is slower than the clock on Earth, and the slower time is the same as that calculated by Einstein's theory of relativity. If all the objects around him are stationary relative to it when we increase our speed infinitely to the speed of light, then if it can exceed the speed of light and distort space, then time will also be distorted, so that it can travel back in time.

Let's take a simple question and think about it: What is the closest distance between two points? If we only think about it in terms of two-dimensional space, it goes without saying that it must be a straight line.

But if the space is overlapped, the two points will coincide, so the space overlap is the shortest distance. Since they can overlap in space, they can also overlap in time.

I think the example of the clock and the distance between two points show that time and space are one and the same.

The above is just a personal statement, let's discuss it.

Theoretically, yes. There are "wormholes" in the universe, and scientists speculate that wormholes are connected to parallel spaces with different times.

The living will never know where they went after they died, so it is possible to cross over. Because there isn't.

No way. You can only go to the future. This is what our physics teacher said.

When you move faster than the speed of light, you can go to the future.

Specifically. You will find that your friends who used to be as old as you are grandmothers and grandfathers, and you are still young.

Of course not, that's just what filmmakers assume to attract attention.

Unlikely to put.

I've seen sci-fi on this subject before. It is to say that a spaceship has created a "wormhole" because it has traveled at the speed of light, and their time is half that of normal time. But that impulse is small and unstable. It is impossible for humans to go through it.

And how do you travel back in time? It is only possible to achieve a time-out connection if it starts from the present time. You didn't have a connection point in the past, how do you connect?

Personally, I think that first of all we should not be limited to science on our earth, for now human beings know almost nothing about the whole concept of the universe, just as we don't know that the universe is boundless or not. In our understanding, we live on the earth and feel that everything has a basis for development, and this is what we call science.

Personally, I think we should think we should think outside of this idea when necessary, we often say that there are all kinds of birds when the forest is big. According to some books I've read, there are endless time and space in our world at any time and in any place, and there are us in every time and space, and if you go back to the past, it's just another time and space that you have returned to the past, not the past that you really came over

Science? Isn't science a pseudo-superstition?

The world is so big, there are so many Chinese, there are always some strange things that we don't know, people who don't know beyond the ordinary, this is like a poor person who can't understand the life of the top rich at all, because he doesn't have that level, can't reach that plane, and life is like this, what you don't know doesn't understand, it doesn't mean that it doesn't exist, because you are mediocre, it's that simple.

It's very simple, but it's a cruel truth.

It is said that more than the speed of light is fine.

Knowledge of high school physics.

How far away is time travel?

Hello dear, if I could really travel back in time, I would like to go back to my high school self. The reason why I made this choice was because I wanted to go back to being young, I wanted to be better, and I wanted to make different choices about the future.

1. I want to travel back to my high school self and regain my youth. When I was in high school, I was in my prime, and I was at the best age. ......As I got older, I cherished that time even more.

Therefore, if I have the opportunity, I would like to travel back to high school and regain my youth and have the best years again. ......This is one of the most important reasons why I chose to travel back to high school.

2. Traveling back to my high school self, I want to make myself better. In the three years of high school, although I worked hard, I still had regrets ......Because of the study methods and other problems, my learning efficiency is not high, and my academic performance is not good enough......Therefore, I want to go back to high school and start over, study hard with higher learning efficiency and better state, get better grades, make myself better, and strive for a better future for myself.

3. I want to make a different choice about my future by traveling back to high school. The major I'm in right now isn't my favorite. I always want to start over ......Therefore, I want to travel back to high school, so that I can choose a new major when I choose my choice, and choose a major that I really like, so that I can have a completely different future and start my life in a new state.

This is the most fundamental reason why I chose to travel back to high school.

If I could travel back in time, I felt like I wanted to go back to school, junior high school.

For many middle-aged people like me, when they reach a certain age, they will sigh the passage of time and the passage of time, and they will be nostalgic for their beautiful student days.

First of all, when I was a student, I was able to have a lot of like-minded classmates, and we were able to play football together in physical education class or during recess, although the pace of learning was relatively tense at that time, and the pressure of learning was relatively large, but whenever I was able to use physical education class or some recess time to play football for a while, we could release the pressure in our hearts, and in the process of football games, we could find real happiness.

Although I still like the sport of football now, I am still a fan, but now I imagine that I am not able to play football when I was a student, looking at my weight of 180 pounds, not to mention playing football, it is more difficult to walk five or six thousand steps every day, so at this moment I feel the beauty of my student days, especially when I was a student, it is really good to be young, and I can enjoy the joy and happiness that football brings to me. In the past, I devoted myself to the sports I loved, and found my sense of accomplishment and satisfaction.

If I could travel back in time, I would most like to go back to the three ages of 14, 18, and 22, because I have the least regrets among these three ages.

1. Back to my 14-year-old childhood, my cat Huanhuan is my best playmate. Every time I call it by name, it immediately runs up to me. When it first came to my house, it was a kitten, and then as time went by, it grew up and I grew up.

When I got to junior high school, I started living on campus and rarely went home. When I was 14 years old, I came home from school vacation, and I couldn't find it, so I asked my mother if it went. Mom was sad to tell me that it had gone to the cat.

It is old, and it has been unable to move recently, and Qi Tian of the Naqing clan who is dying has been lying next to my shoes, as if waiting for me to come back. I blame myself for not being with it in the end, every time I think of it, I regret it, if I can go back to this year, I want to give it a hug and let it have no regrets.

2. I went back to the age of 18 and failed the college entrance examination at the age of 18, and I was not admitted to my ideal school. At that time, I didn't know what to think, so I didn't want to repeat it, so I resolutely chose a random university to study. A few years of college time passed in a blink of an eye, and I worked directly after graduation, but after working, I realized how important a good university is.

After experiencing the experience of society, I regret more and more, why didn't I repeat it in the first place, if it wasn't for my own insistence, I might not be so hard now.

3. Returning to the 22-year-old grandma is the most painful for me, and every time there is something delicious, she will leave it to me. She is kind and simple, and always warms me with her love. But at the age of 22, my grandmother passed away, and she left me forever.

I couldn't accept this fact and collapsed for a long time. If Suixiao can return to this year, I hope to accompany Grandma Yuling more, to make more delicious food for Grandma, I want to take Grandma to see the great landscapes of the motherland, and I will tell Grandma every day that I love her.

So we have to cherish the time, cherish the time that passes every day, because after the time passes, it will not come back, and I hope mine will help you.
