In reality, according to NASA, "we all travel in time."
The space agency has stated that although "we are all travelling in time at roughly the same speed: 1 second per second," "science" suggests that the kind of time travel portrayed in "movies or science fiction books" may actually be possible.
Scientists have conducted experiments to demonstrate that time appears to pass more slowly the quicker you travel. One experiment comparing two clocks—one that remained on Earth and the other that went in an airplane—proved this.
The clock on the fast-flying jet was found to be slightly behind the clock on the ground, indicating that it was going somewhat slower than one second per second, after the plane had circled the globe.
NASA came to the conclusion that time travel is genuine. But it differs slightly from what you've undoubtedly seen in movies.
It is possible to feel time passing at a rate other than one second per second under specific circumstances. We must comprehend this type of time travel that occurs in the real world for several key reasons.
However, if you're on a plane, you might have to wait a little longer. In reality, the only way we're going to learn who made the final is by waiting for that moment.
1)Black Holes
Time travel requires a speed that is close to the speed of light and gravity, which is currently not a reality. However, this modest piece of study shows that a time machine may be created utilising black holes.
A black hole is an invisible object in space that is so dense that even light cannot escape from it within a particular range of distance. Black holes are believed to form when stars or other huge objects collapse under the force of their own gravity to create an object with an infinitely high density that travels at a velocity that is almost equal to the speed of light.
Static, Charged, Rotating, and Super-massive are the four main categories of black holes. The Rotating Black Hole is the one of these four that is most important for successful time travel. Roy Kerr, a mathematician from New Zealand, proposed it in 1963 and contended that it is the most desired because it lacks a singularity. Although the black hole idea was proposed in 1783, Einstein's theory of relativity, which was introduced in 1915, uses it to support time travel.
2) Wormholes
A theorised route through space-time is called a wormhole his hypothesis views the cosmos as a textile. The goal is to use a shortcut to travel from one time zone to another, such from A to B, utilising less speed and energy. Folding this "fabric" universe allows for the creation of this alternate route. As a result, a wormhole has two mouths and a throat that connects them. The two time zones that require travel will be connected by these two mouths.
