If I asked to accelerate an object to the speed of light, how much force would I calculate? Or what

For the time being, no matter what the upper limit of acceleration that humans can bear, it is based on the normal state, so the acceleration of the flying earth will always remain at the acceleration of gravity.

That is, motion at a uniform speed with twice the acceleration of gravity. (This acceleration is determined by the spacecraft.)

Measured and maintained internally, regardless of the pattern of energy) This is an old saying about whether the speed of light can be reached.

The theory of relativity limits the speed of an object of rest to the speed of light, so that the speed of a person flying away from the Earth can only be constantly approaching the speed of light, and we believe that he can reach the speed of light is derived from the Earth's frame of reference). In fact, the analysis of this uniformly accelerated motion still uses the special theory of relativity.

Because the scene we set takes place in the Min plane. If we put another condition to this question:"This person will eventually return to Earth in the same way as Obimin"。

Then the question becomes a twin paradox, but because the answer has already been given, the word paradox can be removed. (However, the most intuitive and clear explanation for the twin paradox is the use of space-time diagrams.)

According to Newton's gravitational force.

and the theorem of motion, we can calculate time and distance. Can an object fly towards a massive celestial body at this distance faster than the speed of light? Relativity.

No, when the speed of light is reached, time stops, the length of the object in the direction of velocity becomes 0, the mass disappears, the acceleration does not exist, it will maintain the speed of light and continue to fly.

So, what can we observe? This is relatively confusing. If it's curvature flight mode.

will not be affected by acceleration, because gravity at the curvature of the speed of light is affected by the expansion of the time dimension. The longer the time, the less gravitational pull there is until it disappears. It can be suspended by a small point force or fly in a certain direction at a very high speed, and according to the theory of relativity, it is impossible for a person to accelerate to the speed of light liters.

A well-trained astronaut can withstand more acceleration. Let's assume an acceleration of 80 meters and seconds and it takes about 10 hours to accelerate to 1% of the speed of light. In fact, no device can maintain such an acceleration.

Personally, I don't think it's feasible to gradually accelerate a moving object to the speed of light with our current means. In order to achieve faster-than-light motion, moving objects must enter the cavity and chain into another dimension that we have not yet understood, in this dimension, all objects can easily achieve faster-than-light motion, and all means of detection, information transmission and processing, motion control, etc. will be completely new. At the same time, faster-than-light objects do not collide with other objects in that dimension or with any objects in our three-dimensional world, and the objects in our current dimension have no effect or non-existence compared to the faster-than-light dimension.

As for the time it takes for humans to accelerate to the speed of light in conventional motion, if we do not consider the effects of relativistic effects when the speed is increasing, the theoretical time to accelerate to the speed of light is about 416 hours based on the extreme acceleration that the human body can withstand for a long time, calculated at 20 g. In our dimension, with the current propulsion technology, this is obviously unachievable.

It takes about a year, through classical mechanics can prove such a situation, about a year, it is possible to make people feel comfortable, but also to make people have an ideal state, can avoid fatigue, in such a bearing situation, the acceleration can reach about 5G slippery He Qi. Puna.

At least one year of inter-chamber inter-chamber is required. The basis is that someone calculated through Einstein's equation and came to the conclusion that it is almost impossible to reach the speed of light, and it will take a long time.

It's fast, can people withstand it on it? It's a question to ponder. As long as there is a relative ore in this world, it can be done, otherwise it will be overloaded****.

It is very difficult for us to reach the speed of light, and only when the mass of our body becomes zero, can we have a chance to reach the speed of light, which we cannot achieve at the current level of science.

According to Einstein's formula for the speed of light, on the one hand, we need enough mass, and secondly, our body needs to be able to withstand the impact of excessive speed.

According to current scientific research, there is no machine that can achieve a light beam. Theoretically, after reaching the speed of light, it is possible to reverse space-time.

Impossible! Theoretically, the force required to accelerate an object to the speed of light is infinite! No matter what material the object is, there is a critical value, and when it accelerates to a certain extent, it will **, shatter into a pile of particles, and it will no longer be able to accelerate!

In fact, once an object reaches the speed of light, it shatters first, then smashes again and again, and finally becomes a beam of light!

Update 1:I agree with the notion that it is impossible on Earth.

But what about in a vacuum?

1.No way.

But that's it. In black holes, however, it is possible (explained in 2)

But it's not possible outside the black hole. 2.Only some very light particles are possible in the vicinity of a black hole. This is because the gravity of a black hole is simply too great.

Will suck everything into it at a very, very fast speed. 3.OK.

I read books. There are some things called virtual particles.

They are in the black hole into the plane.

speed is much faster than light. Off topic: Yes. To sum it up.

I think it's only possible with black holes.

Because strictly it is possible. I have time to add one more 2009-01-16 13:22:04 Added: And.

A big reason why a black hole can be near it is that there's no air.

No resistance 2009-01-16 13:23:35 Added: Add.

Ask a friend of 001.

Isn't light transmitted by particle waves?

It doesn't have to be electromagnetic waves, right? 2009-01-16 13:24:34 Added: Add.

There are no planets in the vicinity of the black hole (if any, they are sucked out by the black hole).

So 001's hidden wheel may be a little wrong. *Just a personal opinion** Not to cause a pen war.

Reference: Yourself.

Xunzi is faster than the speed of light.

1. Yes, not 2. It depends on the weight and size of the object. The size of Wang Xihui is because he is subject to big or small resistance. The weight is due to the difficulty of acceleration.

But it's a different story in space. As on Earth. Click on the car.

Can a train accelerate to the speed of light? e=mc 2 can be illustrated. Because the energy of acceleration is converted into mass.

It's like the greater the mass. The greater the gravitational pull. The faster the better, the higher the quality.

But in space it is not known. Because I haven't tried to do similar experiments in space. Previously, scientists tried to accelerate neutrons to the speed of light.

Collide. There is no such thing as a look"God's particles"..Unfortunately, the experiment was not successful.

3 Unknown 3 Yes. When accelerating upwards and decelerating downwards. weight>reaction ..

The opposite is true. 1.Not on Earth Space should and can't be 2Because although gravity will pull objects to the center of the earth, but at the same time, there will be air resistance, and in the end it will only go to terminal speed, and it is impossible to go to the speed of light, and there is also the gravitational attraction of different planets in outer space, so it should not be possible to exist 3, it is impossible to be faster than the speed of light, and light is transmitted in the form of electromagnetic waves, 4. normal reaction and weight can be used to speed up and decelerate the weight difference caused by acceleration and deceleration in the elevator, if there is any error, please forgive and point out.

Reference: Self-Distress.

Regardless of mass, it is impossible for an object to exceed the speed of light because the speed of light is the ultimate speed in the universe. The speed of light is 299792458 meters per second, and the distance after 300,000 seconds is 300,000*1,000 meters, that is, 300,000 kilometers, and after traveling 300,000 seconds with an acceleration in the direction of 1 kilometer second, the theoretical speed of the object is 300,000 kilometers per second, that is, 300000000 meters per second. This speed is far beyond the limit of the speed of light, so it is impossible for an object to reach the speed of light after 300,000 seconds.

As the velocity approaches the speed of light, the mass of the object becomes larger and larger, requiring more kinetic energy to continue accelerating, but even if all the kinetic energy is invested, it is impossible to reach the speed of light under the current physical and technical conditions.

The speed of gravity is almost equal to the speed of light, and since gravity is not quantified now, the existence of gravitons has not been discovered, but scientists have shown that gravitons are massless particles according to the Standard Model, not only relativity, but quantum mechanics should also have the speed of light.

The speed of gravity is equal to the speed of light, which was first derived from the inference of general relativity, and then confirmed by a large number of observations and established the fundamental laws of the universe.

Because the speed of light is the ultimate speed of the universe, and gravity cannot exceed the speed of light, the gravitational speed must be equal to the speed of light.

The existing theories are not enough to prove that the speed of gravity is equal to the speed of light! The method of measuring gravitational waves is questionable!

The propagation speed of gravity is greater than 0 and less than the speed of light. When it reaches the nucleus, it becomes faster-than-light.

Gravitational velocity is not the same as the speed of light, gravitational force can be an ultra-long-range force
