Is time travel possible now? It's hard to believe, but the definite answer to this question is yes!
1. Scientists have already been able to send a photon into the future
True, only for a fraction of a nanosecond, but this proves that time travel (at least to the future) is quite possible, and translating it to a larger scale has become only an engineering task. All we need for this is a black hole, the Large Hadron Collider, or a super-high-speed rocket.
2. The faster the object moves, the slower it will age
That is, if you go on a space journey with a near-light speed, then returning to Earth, you will find yourself several millennia into the future, although only a few years will pass for you. It remains only to learn how to move at light speeds and a time machine is provided to us!

3. But many scientists think that traveling to the past is impossible
Stephen Hawking believes he has proven this. He once organized a party for the time travelers, and did not announce it until the next day. As expected, no one showed up … Or, for some reason, the chronauts did not accept his invitation.
4. Travel to the past can violate the fundamental laws of the universe, according to which the cause comes before the effect
For example, first you type text, and only then will it appear on the computer monitor.
5. Einstein believed that it is impossible to move faster than the speed of light
Otherwise, the effect will come before the cause. That is, the candle will light up before you light it, and the door will open before you push it!
6. There are a number of paradoxes that will arise for the traveler in the past
For example, if you travel back in time and kill your grandfather before he meets your grandmother, then you cannot be born.
7. There is also the paradox of personality multiplication, so popular in all science fiction films
Imagine that you got into a time machine and transported one day into the past, where you already exist, and you become two. But there is still one who is just going to go to the past, where there are already two of you, and there are already three of you! And so it can go on indefinitely.
8. There is a theory of wormholes, which says that black holes can connect two distant points in space or time
The zero-length tunnel between them is called the Einstein-Rosen bridge, but to get through it, you need to move faster than light.
9. Although Einstein said that it is impossible to move faster than the speed of light, scientists, apparently, have already proved the opposite
They announced that neutrino particles in the Gran Sasso underground laboratory in Italy have done the impossible and surpassed the speed of light!
10. Perhaps the people of the future or an advanced alien civilization have already been able to create a time machine
For travel in the space-time continuum, they can stabilize the wormhole and use it. Otherwise, how can we explain the numerous reports of UFOs, amazing structures, records of ancient civilizations and many other events that do not fit into the generally accepted picture of the world?
