On the question of time travel, whether time and space can be traveled

Impossible, time travel requires many conditions to complete, and it is impossible to achieve it with current human technology. And crossing isn't necessarily a good thing, although everyone wants to try it once. Because the era you travel through is difficult to determine, and if the time gap is unstable, the consequences are unimaginable, and it is possible to travel you to a new world in the future, and it is possible to come back; It is not impossible to travel to a prehistoric civilization, or to the belly of a dinosaur and digest it as food.

There is only one way to generate a time gap: super magnetic field (used to find the gap, humans can't stand it) + greater than 50 times Pierre's speed (not the speed of light, faster than the speed of light) + anti-compression suit + flying device + ......Anyway, no one can afford to use it once.

Don't trust high-speed rotation to traverse, high-speed rotation will only break down human tissue.

A lot of articles and movies and TV shows have been talked about, and I don't know which one you're talking about, but it's impossible to get to that speed in terms of physics.

Crossing is not limited to going back to the past, but also to the future, or to parallel space, parallel worlds, parallel universes, or the same time and space and the same era, A to B. It is also possible to wear empty, to an era with no historical record (overhead), and it is also possible to wear to a different time and space (fantasy civilization, fairy and demon civilization, fantasy civilization, etc.). The possibility of time travel Most scientists agree that time travel is possible, but what exactly does it take to travel through time and space?

Faster-than-light? Does it take faster than light to traverse? Not really, because the speed of light is the fastest in the universe. So what exactly does it take to cross?

Coordinate system. Anyone who has studied mathematics knows that each point in a coordinate system has a unique coordinate, and if one of the coordinates is wrong, the point represented is no longer the original point. What if the space-time we live in also has coordinate points?

If we look at the universe we live in as a four-dimensional space, then each of us has a unique coordinate (x, y, z, h), if we change one of them, for example, change the coordinate h that represents time, then does it mean that we have crossed over? Right! So just change one of our coordinate points and we can make a crossing.

And not because of faster-than-light! But modern science has been able to come up with the argument that both crossing can happen and original crossing can happen. But memories after soul travel cannot exist.

Because modern biology has proven that human memory exists in the brain. For example, you have crossed over (soul crossing) and you have just woken up at this time. Then you don't have the memory of before the time-travel, you just think "a new day has started again, what should I do?"

Instead of saying, "Haha, come back and pull again!" I'm going to rewrite my life! ”

Well, there are deep questions ......I think so

If the speed of light is exceeded, it can be traversed.
