Mizukawa looked at his phone: Do you think time can be changed, and can time travel be realized?

Liuzi Fenglai drew a watch on paper: to answer this question, it is necessary to be white-voiced about what time is. The essence of time is how fast or slow our behavior is relative to a standard moving object, which is usually fixed. As soon as the standard object changes, the time changes accordingly. Although crossing has become an element of rotten streets, crossing is inherently impossible.

Dueñas said: The prerequisite for crossing is to have a timeline, otherwise crossing is impossible. If there really is a timeline in the universe, then the timeline must contain infinite energy. If the timeline exists, then where will it be? In the Spanish sci-fi TV series "Time Authority", it is said that teleportation can be achieved through different portals. Now that there's a timeline, what about portals and the like? Absolutely. The function of the timeline is to record time, which is actually equivalent to a camera. And the portal is the tool to traverse. I think the portal is in the timeline. If the timeline doesn't exist, traversal is impossible.

However, I think the crossing is different from others. When a traveler enters a certain point in time in the past, they can only watch and not enter. Because you're traveling through a point in time, not a timeline. Therefore, it is completely impossible for the time-traveler in the TV series to start living at the time of crossing.

Margarita said: We know that crossing can cause paradoxes. The grandfather paradox is known to everyone, and it is also something to be avoided in film and television dramas. The paradox tells us that traversal is not arbitrary, but has a price. Like my sister said, have a timeline. Frequent traversal is likely to cause the timeline to collapse.

Mizukawa looked around: I think it is feasible to cross, and it is not possible to teleport. How so? It's where you are, and where you are after the crossing. This is called the traversal correspondence principle. We thought we could open the door to our minds and imagine as much as we wanted. However, physics is constrained. Traversal and teleportation are not one and the same, but two different phenomena. Of course, we do not rule out that the traverser has mastered teleportation. However, the probability of this happening is very small. I know what Dueñas said about timelines and portals, but if you think about how many portals are needed in so many places in the world. Each portal won't be able to get you exactly where you want to go, just like each phone doesn't have a server.

I have a question: Is the timeline very long or short? I tend to be very long. Although the portals in the timeline do not cover all locations in the world, there are many of them. I think it takes a long time for you to pick a portal, let alone get to the right place.

Doujin taboo! One cannot be present at two points in time at the same time, otherwise paradoxes will arise. In order to prevent paradoxes, this person is likely to be eliminated.

Carry restricted areas. At the point in time, the traveler is not allowed to take anything with them. Otherwise, the timeline initiates incineration. The timeline incinerates the object, leaving no residue behind.

By the way, what else do you want to say?

All three replied: We feel that there is nothing we can do, what you say is what we want to say. You can't help but think about anything, and so does time. Although we have thought about it a lot, we still do not get to the heart of the matter. If given the opportunity, we would like to discuss this topic again.

Mizukawa sighed: That's it for today!
