Time travel is the act of traveling to the future or the past. It is the action of moving from different points in time, although time travel is considered science fiction, there are many scientific aspects to prove it. Say no to plagiarism.

For some physicists, time seems to be the fourth dimension of reality. Time cannot go backwards according to how thermodynamics works. The second law of thermodynamics states that since the world is a closed system, the constancy of time remains the same or increases. Time also varies depending on your speed in space according to Albert Einstein. Einstein's theory of relativity states that "time slows down or speeds up depending on how fast you are moving relative to something else." An example of this would be that when astronauts go into space, they age more slowly than everyone else on the planet, because in space, time is different. This theory is called time dilation and is considered a form of time travel for astronauts. An official way to travel through time would be to go faster than the speed of light in a vacuum. But this turns out to be mathematically impossible, but some scientists have expanded Einstein's equation and said it could be possible with small particles. Another possibility would be to create a wormhole for travel. Wormholes are holes that you travel through to access another part of the universe. Together with Einstein's equations, this proves that there could be wormholes that travel through time, but no scientist has observed one yet. Sir Isaac Newton thought time was the same, an example would be that a second on Earth would be the same. like a second on Mars. He believed that all the clocks in the world ticked at the same speed. But Einstein didn't follow this rule, he saw time as a river, but instead of a river flowing through different parts of rocks, he explained how time traveled differently around galaxies. Each part of a river has a different speed, and he considered time to be the same thing. In different parts of the galaxy, time would flow at a different rate than in other places. Kurt Godel found a solution to one of Einstein's equations that allowed time travel. A “river of time” mixed with whirlpools could allow time to envelop itself and create a time machine. Anyone who walks in the direction of the temporal rotation would be able to return to the starting point which is backward in time. Einstein didn't like the fact that his equations allowed time travel. Ultimately, Gödel's solution was universal because the universe does not rotate but in fact it expands. In 1963, another mathematician found a solution to Einstein's equations and his name was Roy Kerr, because this time it was a spinning black hole rather than a rotating black hole. whirlwind. The black hole would evolve in a rotating circle. This annular circulation would become so fast that the force would prevent it from falling under gravity. These apparent “black holes” can be used as time machines as well as to travel to different parts of the universe. Many other solutions have been found to use wormholes/black holes to travel to different eras in the universe, but none of them have been,.
