What would happen if the vehicle was equal to the speed of light, and what would happen if it exceed

When a vehicle is flying at the speed of light, it is the time inside the aircraft that is stationary, and the time outside is not stationary.

After the aircraft flies out, people can still see what it looks like when it flies out.

So how long the aircraft has been flying outside the earth, how long has passed on the earth, but the pilot in the aircraft does not know the passage of time. Because time in the aircraft is stationary, the changes in matter inside are also stationary, the pilot's body is no longer metabolized, and the brain has stopped thinking, so the pilot will live forever unconsciously.

If the aircraft flies faster than the speed of light, the time in the aircraft will also be reversed, and the pilot will be able to rejuvenate. However, his knowledge and experience also go back in time, and he doesn't know anything about things on the plane. However, time passed outside the aircraft.

Of course, these are all inferred from the theory of relativity, which is impossible to achieve, because the speed of light is the ultimate speed.

If a vehicle is traveling at the speed of light (isoluminal speed) and departs from the Earth at 0 seconds on January 1, 2008, what time will it be when the aircraft travels a certain distance and returns to the Earth? Was it after 0 seconds on January 1, 2008? Or before?

The same assumption, what if the speed of light is 1 times faster?

Turn back the clock! It's about going back in time.

For those aircraft that we call aliens and UFOs, can it be understood that the aircraft (UFOs) created by human beings after the N generation of our earth with advanced science return to the current earth?

Whatever you want, you can't do it.

Albert Einstein made the assumption that there would be many incredible things close to the speed of light, and that transcendence would turn back time, but the theory of relativity denied that there was any ship that could be so good

Faster-than-light will take us back in time. Or use the super-large gravitational force to bend the space extremely, and go somewhere else without having to go all at once.

This one is not available at the moment; The closer matter is to the speed of light, the slower its time passes. (as opposed to other substances). Once matter is equal to the speed of light, time stops passing.

Of course, the closer you get to the speed of light, the more energy you expend will increase to the nth power. If it really exceeds the speed of light, the time of this matter will theoretically be reversed. (The problem is that even if you spend an infinite amount of energy, you are infinitely close to the speed of light at most.)

It is impossible to reach even the speed of light. So theoretically impossible. ）

The reason why elementary particles such as photons, electrons, etc., can reach the speed of light is because their mass at zero velocity is zero. That's why we can reach the speed of light.

In fact, sometimes the explanation is very simple, in space physics, space and time are closely related. I'll give you an example, and you'll probably see why. Take sunlight as an example, since it takes 8 minutes and 23 seconds for sunlight to reach the earth, in other words, the sun you see is always the sun 8 minutes and 23 seconds ago.

Light travels at the speed of light, so in space physics, distance is sometimes expressed in terms of time, such as the familiar light years. A light-year is a distance of light that has one year. There is both time and space in it.

All that's left is to solve the problem of exceeding the speed of light. You should draw a timeline, you are standing at this point, the sun is 8 minutes and 23 seconds ago, if it exceeds the speed of light, then don't you see the sun 8 minutes and 23 seconds ago? So if you exceed the speed of light, time will go backwards.

In general relativity, it is not allowed to exceed the speed of light.

It is estimated that there is not, and I would rather develop space conversion than develop light-speed aircraft, because the centrifugal force is too great at the speed of light, and people will squash it.

Unrealistic, the speed of light is the ultimate speed, which can only be approached, not exceeded.

Impossible, an object with mass tends to be infinitely massive at the speed of light, and at the same time requires an infinite amount of energy, which is not that much energy in the entire universe.

You can check out the book "Stargate - The Faster-than-Light Principle of Space Vehicles". The aircraft can fly faster than the speed of light.

Unless human scientific theories are so powerful that they break through the current scientific theories, it is impossible to reach or exceed the speed of light! Because when you reach the speed of light, you become some kind of energy, and according to the theory of relativity, when you get close to the speed of light, your mass will become infinite, and your body will not be able to withstand that huge mass and be crushed ......

When the flashlight was used to make the track, everything was burned everywhere the beam of light went.

Not very realistic. The speed of light is the ultimate speed of human beings.

Einstein's mass-energy formula can be calculated that humans can only get infinitely close to the speed of light, and it is impossible to go beyond it, just like absolute zero.

According to the theory of relativity, the closer the speed of motion is to the speed of light. The slower the passage of time.

Therefore, astronauts feel that the passage of time has nothing to do with the distance traveled, but with how close the vehicle is to the speed of light. According to the current human theory, the speed of light cannot be exceeded, because when the speed of light is reached, time will be relatively static. So the speed of light can only be infinitely close, not exceeded.

You can be 99% of the speed of light, or it can be the speed of light, or it can be the speed of light.

The closer you get to the speed of light, the slower the passage of time will be. Depending on the frame of reference, time will speed up when you see objects around you. When you fall out of the speed of light and return to normal speed, the world has passed hundreds or thousands in an instant.

If the speed of light can be reached, interstellar travel may not be difficult. But you're going to face a tougher problem.

For example, if your alien friend is 10,000 lights away, and you reach its planet at the speed of light, you will find that the place you have arrived at is actually the planet 10,000 years later. You are still alive, but your alien friends have long since become the ancestors of the ancestors. Maybe there is no ancestral tablet left.

So the speed of light is a very slow speed on a cosmic scale. If humans have the speed of light, they can only go to one place, and that is the future.

There is currently no formula that can be applied to calculate the speed of light and time in detail. Therefore, we cannot know how long it has been in reality since an astronaut flew 10,000 lights at the speed of light.

In short, it's a long, long time. Maybe when he returns, the earth will be gone. I don't know if you have basic knowledge about the speed of light, the theory of relativity, and quantum theory.

I'll assume you have, so I won't explain the process, but just say the result: under absolutely perfect conditions, it is possible. But what you see is not in order, but in reverse order.

If humans are flying at the speed of light, it means that humans are developed enough to have a cross-cutting event, and they can also reach another planet or another dimension at the speed of light.

According to Einstein's equation e=mc2, close to the speed of light, the mass of human beings becomes very, very small, almost equivalent to the state of particles. Therefore, it may be granular at that time.

According to the theory of relativity, time slows down when approaching the speed of light, so that a person in flight will grow more slowly than a normal person on Earth.

The fundamental reason is that scientists today have not yet discovered a speed faster than the speed of light, so it cannot be surpassed.

The fastest propagation speed of an ability is the speed of light, and if the speed of an object exceeds the speed of light, the energy cannot keep up, so it can no longer obtain energy and is accelerated.

Because according to Einstein's theory of relativity, if the speed of light is exceeded, then space-time will flow backwards, but space-time will not flow backwards, so the speed of light cannot be surpassed.

Because the photon that drives the speed of light is the particle with the highest energy known to mankind, and there is no ion higher than the energy of the photon, the speed of light cannot be surpassed.

Because the speed of light is the fastest speed in the world, the speed at which no object of any kind can reach under special circumstances.

Light has no quality, can you do something without quality! When can it be done without quality, let's talk about transcendence!

The speed of light is frequency, and matter is also frequency. Light is energy, and matter is the concrete into which energy is transformed. Therefore, the frequency of matter must be lower than the frequency of light, and velocity can also be understood as frequency.

When matter approaches the speed of light, matter will be converted into an energy state at frequency, and without matter, no matter can be established faster than the speed of light. ...Superposition under frequencies, the upper limit of the restricted frequency, i.e., the speed of superposition does not exceed the speed of light. Unless you provide a superposition frequency that exceeds the frequency of light, then you must first exceed the speed of light before you can successfully superimpose the superlight speed.

…The speed of light is the upper limit of speed, and if you exceed the speed of light with speed, you are subject to the rules, and you can't do it. ...All the settings, all the ceilings, are used to break through. Before the breakthrough, it was because the accumulation of the foundation was not enough to pry open the seal.

This thing, with rules other than speed, to break through this setting, many paradoxes seem to be unsolvable, jump out of the limitations of the system, and the solution will come out. It can't evolve a life that is higher than ecology, and it can create people. Matter can't confine the high temperature of 400 million degrees, and it can be restrained by a plasma magnetic field.

Because no matter how fast you go, the speed of light you measure remains the same.
