Do you have only a vague idea of how and by what means the time machine works? Not to worry: let's find out how it actually works.
The time machine, which, unfortunately, no one has ever invented, can be difficult to understand (in fact, how can anyone understand an object that doesn't exist?) - sometimes even devoted Doctor Who fans who are immersed in sci-fi pop fail to do so.
Not everyone is able to comprehend how it can, at least theoretically, be organized. In this article, we answer the most popular questions and try to understand the mechanism of the time machine.
Einstein's hypothesis
There are three hypotheses about how a machine that allows one to travel "through time and space" can be constructed. The first belongs to the well-known physicist Albert Einstein and is closely related to his theory of relativity. According to this hypothesis, time travel is possible if an object moves at the speed of light. The jump in time occurs due to the fact that time for the object relative to others slows down.
Imagine a popular scene from even non-fiction movies: the main character literally "flies" across the screen like a real ninja, while time slows down for everyone else: people bring a sandwich to their mouths with murderous slowness, their lips curve incongruously, and many fall for hours after slipping on a banana peel.
Cryo-freezing
Cryo-freezing is another method that, in theory, will allow you to make a time jump. By freezing a person half to death, he can be "preserved" and thawed out centuries and millennia later.
In fact, some animals (bears, for example) have long surpassed us humans: they fall asleep at the end of fall or beginning of winter and wake up only in spring. Isn't that time travel?
Quantum physics
Another method is related to quantum physics: time travel will become possible when we learn how to move quarks - the smallest particles - and units of information in space and time in a matter of moments.
something like an atomic fissioner, only more finely tuned.
Problems
So, if there are ways to create a time machine and even look more or less adequate, what's the problem? But there are several at once.
To test the first hypothesis will require a lot of power and money: even assuming that we can "accelerate" the fastest that we now have - which is the solar probe "Parker", moving at about 700,000 km/h - money for all these experiments will be incredibly expensive. In addition, we will have to take fuel from somewhere: as you understand, there are no "Lukoil" in outer space so far.
To freeze ourselves, like a chicken breast in a refrigerator, in order to jump through time using the second method, we also can not yet: the biological limitations of our body.
As for quantum physics - it is easier said than done: it is impossible to improve current knowledge and get new ones in a second. Such a process is long, it will inevitably require a huge amount of time, even if we dare to put all our efforts into it. This is how a time machine can be set up. Which hypothesis do you like best?
