Is there any definite basis for traveling through time at the speed of light?

Physicist Albert Einstein mentioned this assumption in his theory of relativity, as for the theory of relativity, you can simply understand it as "the moving ruler becomes longer, the moving clock becomes slower", that is, to see that the fast-moving ruler becomes longer, the fast-moving clock slows down, when a person has been moving at a very fast speed, the time in the space he is in will slow down relative to the outside world, of course, this change is minimal, imagine that if a person can move at the speed of light, the interior time of the space he is in is very fast relative to the outside world, Then his time slows down, and he can see that everyone else is old, and he is still young. This is just an assumption, no aircraft can reach the speed of light at present, and it is even more impossible to exceed the speed of light, maybe one day, with this kind of "plane" that exceeds the speed of light and can even move in the negative direction of the time axis, we will be able to take it to see our deceased relatives. Hehe.

If the universe continues to expand, it can reach superluminal speed as long as it can be kept still, in an absolute position.

Time travel exists, because the universe has generated time and space in the big **, and in life, the space around us is constantly changing, just like an apple falling from a tree, space changes, that space can change, that time can also be, if the speed of a spaceship is equivalent to 99% of the speed of light. At this rate, a day on a ship means a year on Earth. The passengers on the ship are flying into the future in disguise, making a veritable time travel.

The tunnel of time (9 photos) There is also the size of the matter can affect the speed of time flow, just like the Global Positioning System (GPS) above our heads, they flow faster than the Earth, so we have to change the GPS time every day, otherwise our navigation system will be off 9 kilometers. There are also wormholes all around us, but they are too small to be seen with the naked eye. Everything in the universe has small holes or cracks, and this basic law also applies to time.

Time also has subtle cracks and voids, and voids smaller than molecules and atoms are called "quantum bubbles", and wormholes exist in "quantum bubbles". One day, humans may be able to capture a wormhole and enlarge it enough for humans or even spaceships to pass through it.

It can exceed the speed of light, because the limit of the speed of light is only in this space, and jumping out of this space can exceed the speed of light. Acceleration can be achieved by distorting the space around you, also known as "warp propulsion".

It's all inferences, no evidence.

If a person travels to a planet 100,000 light-years away in a light-speed vehicle, he will starve to death on the spaceship after 10 days. Continuing his journey of 100,000 light years, if he goes back and forth to the planet of a light as if he had made a rocket, nothing has changed, and if he comes back and sees that humans turn into turtles and move slowly, humans will feel that he is aging rapidly. If he comes back and turns into a turtle with slow movements, he will feel that the human being is dying of rapid aging

If humans were to travel at the speed of light, their bodies would age rapidly. Because time is a state of accelerated loss in human beings. Therefore, human beings travel at the speed of light, and in an instant, they will reach a state of aging.

I don't feel it. Because time is relatively static when an object reaches the speed of light, humans would not feel it if they traveled at the speed of light.

Theoretically, it is possible, as introduced in high school physics books 3-4, 1 The faster the object moves, the slower time will be, and when the speed is close to the speed of light, time will stand still.

2 As a corollary, if the speed exceeds the speed of light, time is reversed.

3 In fact, if the speed of an object is close to the speed of light, then its mass will be infinitely greater, and it will no longer be able to accelerate.

4 The conclusion is that we can only accelerate objects without mass to the speed of light.

5 So, if you want to cross, there is a theoretical possibility: someone A, collect all his information, destroy it, travel faster than the speed of light in the form of information, and completely replicate it after reaching the destination. It's also a crossing.

That's it, please adopt!! It's completely hand-punched.

Theoretically, according to the theory of relativity, time is also a relative concept, if you are running at high speed, and I don't move, then your concept of time is not the same as my concept of time, if you move at close to the speed of light, then the time span I see to you will become very small, which is the so-called your time slowing down, but in fact my time is still the original reference, no different.

And for you, the relativity of space-time is made possible by the movement in the dimension of time, your state is transmitted at the speed of light to the next dimension of time, and when your speed exceeds the speed of light, you will get there before your current state, then what you see is your previous state, which is called time rewinding.

No, because faster-than-light objects slow down in time.

Of course not, according to Einstein's special theory of relativity, beyond the speed of light, space, time, the shape of objects, mass, etc. will change, if you want to go back to ancient times and beyond the future, there is a term in modern physics called wormholes, maybe it's okay, you go to the Internet to look up the term "parallel universe", it will help you with questions.

Now that human civilization has developed to this day, there are many scientists who hope to break through the limit of human speed, and now there are many means of transportation that are getting faster and faster, such as the bicycle developed by human beings at the beginning, the car developed later, and then the airplane developed later.

And now human beings are constantly breaking through their own limits, that is, hoping to one day break through the current speed limit, so that the speed of the object can reach the speed of photons, and then reach the speed of light, at present, human beings hope to be able to find a little faster than light, the fastest speed in the universe is the speed of light, in the universe, scientists compare a distance, often use light years to see the speed of light, how fast it is.

However, scientists feel that there may be faster matter than light in the universe, scientists have found that the speed of neutrinos is faster than the speed of light, scientists have done different stages of speed tests on neutrinos, in the 80s of the last century, through pulse waves to neutrino speed test, the measured speed is actually equal to the speed of light, and later someone changed a speed increaser, did the same speed.

This time the speed of the neutrino was calculated through the formula, and after the median of this speed, it was found that the speed was slightly greater than the speed of light, but people still thought that the speed of light was the fastest due to their daily way of thinking, and there were many uncertainties in this experiment at that time, and everyone felt that the research results brought by this experiment were of little significance, and later scientists observed the process of a supernova explosion, and detected neutrinos with special instruments, and the light had reached the earth three hours before it reached the earth.

At that time, people still did not realize that the speed of light was slower than neutrinos, and even more inclined to neutrinos, which were earlier than the explosion of light particles, until the 21st century, relevant scientists through continuous updating of equipment, technology became more and more mature, and finally determined that neutrinos move faster than photons, this is because neutrinos are smaller than light particles, and can have a larger range of action, which is convenient for scientists to observe.

No. Because according to the theory of relativity, it is difficult for humans to exceed the speed of light, so time travel will not be possible.

Time travel will be possible; Since faster-than-light matter has been discovered, time travel is just around the corner.

Photons travel at the speed of light, so for photons, it reaches the earth from the surface of the sun, and then it is received by our eyes or detectors, and the whole process happens instantaneously in the eyes of photons. For the photon, it does not experience the journey from the sun to the earth at all, so it does not feel the passage of time at all, and the speed of light travel is to reach the destination in an instant, but we do not feel the process and pleasure of travel at all.

If we can fly at the speed of light, it means that we can travel through time and space, and for us, it means that we can travel back in time, even into the future.

If we humans can reach the speed of light, we can travel through time and space to some extent.

Light-speed travel is indeed out of reach for humans, but what it means for us humans is very important because we may have to rely on light-speed travel if we want to achieve habitability in space now. As we all know, currently, humans use the speed of light to measure the distance between planets. In other words, when the speed of light is theoretically reached, the distance traveled at the speed of light for a year is called a light-year.

This planet, but because humanity has not yet reached the level of science and technology to achieve light-speed travel, the interstellar travel plan cannot be realized. Of course, if humanity does one day make a breakthrough in the field of science and technology and reach the speed of light, then even beyond the indictment, the dream of humanity may come true. Of course, in addition to the speed of light, the following can help us achieve our goals:

What would you see if you traveled at the speed of light? How is it different from Earth?

He can think of **go**, and even travel through life, and everything that happened in the past will be revealed in front of his eyes one by one.

If someone can travel at the speed of light, they may not be able to see anything, because the speed is too fast, the eyes are spent, they can't see anything, and they may vomit.

He will not be able to see anything clearly. Because the human eye can't keep up with such a rapidly switching environment, the brain can't handle it.

Albert Einstein proposed that the speed of light is fastest in nature, and when an object travels close to the speed of light, its mass increases infinitely.

As can be seen from the above, event A is one year apart from event B (B occurs one year after the end of A), but the planets that occur are four light-years apart, and if they travel at the speed of light, it will take four years to reach them, and then Event B is over, so to reach them within a year, you must travel more than four times the speed of light to reach Proxima Centauri before B happens.

If A to B is far away is the if.

If you move faster than the speed of light, will time go backwards?
