If humans traveled to the past in the future, would they really be able to meet their past selves?

Captain America would probably be very reflective. He might see his past self as a reminder of his long journey and how much he has changed. He could try to offer some words of wisdom to his younger self.

Their interaction would be very interesting. They would probably be very curious about each other. The present - day BTS might want to give advice to their past selves, like how to deal with stress better during their early days.

Well, they might be shocked at how far they've come. Maybe their past selves would be in awe of their current achievements. For example, seeing the huge stadiums they now perform in compared to the small practice rooms in the past.

At present, there was no evidence to prove the existence of people who had traveled to ancient times or the future. Imagination of traveling to ancient times or the future often appears in literature, movies, and anime, but these imaginations are usually based on fictional stories or theories. In science, time and space are related. The theory of relativity in modern physics shows that the passage of time is related to the position of objects. Therefore, if a person traveled to the future, his or her time would pass much slower than the modern time, which would cause him or her to be unable to adapt to the modern environment and life. Similarly, if a person traveled back in time, his or her time would pass much faster than in the modern world, which would cause him or her to be unable to adapt to the ancient environment and life. Although some people have proposed the idea of traveling to the future, these imaginations are usually based on fictional stories or theories. There is currently no scientific evidence to prove that there are people who travel to the future.

A possible plot could be that the meeting causes some sort of time rift. The Avengers then have to fix this rift while also dealing with the differences between their present and past selves. Their past selves might be more naive or idealistic in some ways, which could lead to both comical and tense situations.

In the fanfiction, the past demigods' powers could be more closely tied to nature and the gods they descend from. Their powers might be seen as gifts directly from the divine, and they have to rely on their own instincts and training to use them. Future demigods, with all their technological advancements, might have powers that are artificially enhanced. They could have power - ups from special suits or implants. But this doesn't necessarily mean they are stronger. The past demigods' natural connection to their powers could give them an edge in certain situations, like when it comes to long - term battles where endurance and a deep understanding of the power source matter.

Therefore, traveling to the past was just a plot in a novel and not a real situation in the real world.
