According to what we know so far, a person at twice the speed of light He can’t possibly move. In fact, it seems impossible for any object of any mass, not just humans, to move faster than the speed of light.

This constant is considered one of the best theories of physics today. Albert EinsteinIt is based on the theory of relativity. According to this theory, the speed of light acts as a strict speed limit for anything with mass. Is it really possible to move faster than light?

Can a massive object accelerate to the speed of light?

First of all, it is necessary to look at what it takes to move an object by mass. The more we want to accelerate an object, the more We need more energy. Looking at the equations of relativity, it is necessary to accelerate a mass object to the speed of light. infinite amount of energy you need But no matter how big the universe is, its energy is limited. This leads us to the conclusion that we cannot accelerate anything with mass to the speed of light.

So is it impossible to double the speed of light at all? Maybe it’s a possibility.

The speed limit imposed by the theory of relativity applies to “ordinary mass”. However, the ‘imaginary mass’ hypothetical particles called tachyons, can change the course of business. There is no evidence that tachyons exist, but their possible existence cannot be ruled out.

The tachyons must move faster than the speed of light.

If tachyons exist, they must move faster than the speed of light. Just as matter with normal mass cannot accelerate to the speed of light, tachyons cannot go below the speed of light.

According to some physicists, tachyons are constantly traveling back in time.

You may have heard the name tachyon before in time travel movies or books. If tachyons really exist to go back in time a way can be found. Of course, for this we must first discover that the tachyons really exist, and then start checking these tachyons. We’ll have to wait a bit longer to go back to the past, because what we currently know about tachyons is just conjecture.

Today’s hypothetical theories may be tomorrow’s reality.

Much of what has been discovered so far has been just a guess. The knowledge we have obtained in science is a jigsaw puzzleWe continue to shape it as parts of . For example, if we found the location of a blue piece, it’s easier to guess what should be next to it. Scientists offer theories with a similar logic.
