Theoretically, it is possible to go 100 years ahead! So How?

So far, we have seen elements of time travel in many parts of the entertainment industry. Back To The Future We can cite the vehicle in the movie as an example. Although such tools appear in different media and in different forms, they all have a common purpose: enable time travel.

Since these subjects and tools came from the producers of the cinema and game world, they were hardly considered realistic. But the physicist, who is known all over the world and has done important studies, Stephen HawkingIn fact, time travel is theoretically possible. had said. Moreover, starting from the concepts of fourth dimension and velocity.

Let’s start slowly: What does this have to do with the fourth dimension and speed?

Let’s start with the concept of size. constantly around two-dimensional, three-dimensional We hear terms like If we start with the first one, one dimension is often expressed with a line. A single variable is all it takes to find the points to put on this line. Only forward or backward you have to go.

One for two sizes paper we can take as an example. This paper we have both width and length has. So it is two dimensional.

In three-dimensional objects, this is also height we add. When we look at prisms, we consider them three-dimensional because we use these three dimensions on them.

But apart from these, time There is also a fourth dimension known as So why is there a time between these variable values? Doesn’t the 1 second that passes here pass at the same speed at every point in the universe?

The answer is no: For this, let’s look at the information that Einstein put forward.

According to Einstein, as the mass of an object increases in space, time at this rate bends and it slows down. For example, the celestial bodies that we know most of the time have much larger masses. in black holesWe have heard that time passes more slowly.

This theory is explained with the following example: In a spacecraft three astronauts Let’s imagine it is. Let one of them have entered the black hole and managed to get out after a few minutes – even if it was impossible. The few minutes that have passed for him, according to the mass of the black hole, have passed outside. equivalent to many years may come. So it’s kind of like time travel.

or time in space flow faster We can cite reality as an example. What makes this difference is the mass of our Earth itself.

Hawking envisions a scenario where an imaginary spacecraft is orbiting a black hole and the mission is tracked from Earth: Each orbital tour takes 16 minutes.

But these 16 minutes for those on Earth are also for those on the spacecraft. is it the same? Our answer is no, this black hole, whose mass is equivalent to the mass of millions of Suns, therefore warps time, and time moves more slowly for those in spacecraft that are very close to it. In this context They experience 8 minutes of the 16 minute tour.

The black hole example also shows that speed is a very important factor in perceiving time. So who would want to jump in a spacecraft and drive them into a black hole in the middle of our galaxy? Not us… Fortunately, Hawking thought of that too:

And as a result, he set up a scenario that is also theoretical. In this scenario our fast train and it tours the world. This train should have speeds close to the speed of light and continue on its way without stopping for an extended period of time. Your light for those who don’t know 300,000 km per second Let’s say you can go.

Any object that has mass at the same time cannot exceed the speed of light is also known. For this reason, our train will only approach this speed. In this context, while the passengers are sitting in the train in question as usual, they see the Earth. about 7 times per second they will be touring. We assume that the train maintains this speed as long as it runs.

Now, time starts to flow more slowly for those inside the train, just like in the case of a black hole.

Hawking said that as the train was moving at this speed, a child inside him, run It also says that it cannot exceed the speed of light. The reason for this is that due to the laws of nature, the time in the train will have slowed down. In other words, the predominance of the speed of light is preserved.

Time inside the train now flows more slowly than outside, despite being on the same planet. What if the train we sent in 2022 toured the planet for 100 years? What year will we be when it stops?

The answer is quite simple, isn’t it? If you spend 100 years from 2022, you will reach the year 2122. But that’s not the case for the occupants of the train. It’s just that time passes more slowly for them. In 1 week they will have gone 100 years ahead.

It can be said that it is impossible to build such a train and a road for this train at the moment. So this idea seems to remain in theory. However, what the science world can do to the future time travels It’s very exciting to see it possible.
