Do you believe in crossing, is crossing real?

Through? I don't agree with this, for example, you returned to the Three Kingdoms, but in modern times you will disappear, and this point in time is different from the point in time that you crossed, when the times change again, history will also follow the development, then there will be no more "you" in the future world Let's just say it, that you can't appear later in a history, so how can you cross over? This is obviously a very contradictory question, which is impossible to exist according to common sense!

But I still have one more point, since I can't travel to the past, can I travel to the future? This is also a very contradictory question, because the world, this era is constantly changing with the rapid development. Theoretically, if you travel from this point in time to the next few decades, then history will also stumble you, that is, if you are a **, and the result is inexplicably traveled to 30 years later, then a key figure will disappear from then on, and suddenly come to the future, then how can the previous history develop with you Alas In short, it is difficult to understand through time and space How is this world, let him go.

The end of the world in 2012 can be understood as a natural disaster or a man-made disaster, so is it a natural disaster or a man-made disaster, or nothing will happen? Everything is unknown! But I still believe that when everything starts again, there will be an end to it, but we don't know when it will happen!

Because we're being so small.

Crossing, maybe it's true, isn't there a wormhole? It's just that the current level of science is not up to it. As for 2012, it's really nonsense, now many scientists don't approve of it, and the Yama people don't mean the end of the world, it's just that a new cycle of the world has begun.

If you believe, you have, and if you don't, you don't.

Crossing Ah, I think it should be a product of the development of science and technology, and in the future, I will organize a tour group to go to ancient times to play.

You turn on your TV, crash into it and you're through.

Crossing has always been an enduring topic. There are many people who always believe that crossing is a real physical phenomenon, and you see that Einstein loved Uncle at the beginning, doesn't it prove the existence of a "wormhole"?

Maybe one day we will encounter a wormhole, and then travel back to the Qing Dynasty through time and space.

The most famous paradox is the grandmother's paradox: if someone travels back in time and kills their grandmother in the past, does he still exist? If not, then who killed it? No matter how you put it, the logic doesn't make sense.

To understand this problem, let's first look at one thing: the decoherence theory of quantum mechanics. This thing may be able to solve all the problems caused by "traveling through time and space".
