You've probably heard more than once about various time travel and that strange people appeared as if out of thin air and looked completely unusual for this era. Such people seemed to have moved in time for moments and often themselves did not understand where they were and how they got there.
Such people are often not dressed for the time and they have things with them that are not typical for a given century or year. Where do they come from? People know too little about time and space, and there is a version that our Universe is not the only one. If other Universes exist, then time there may go differently or be completely absent. And if it goes in the opposite direction? The creature is born old and gradually gets younger, as in the movie about Benjamin Button.
Despite all modern achievements, people know too little about the structure of our Universe and it is foolish to deny the possibility that time can be a variable value or be completely absent. As well as space and the possibility of the existence of parallel worlds. I believe that time traps also exist in nature and people can fall into them by accident, for example, just walking through the forest or even being in their own bed. Fantastic? Maybe, but I do not pretend to be an expert, but simply share my opinion.
Space and time can stretch and holes can appear in them. Let's remember the famous theory of wormholes in space, with the help of which, in theory, you can get to other Universes, and maybe move in time. I note that many respected scientists have advocated and continue to support this version and believe that time travel is quite real.
It is possible that in years or centuries we will learn how to manage holes in space and learn how to move in time, but for now it only remains to build hypotheses and guesses.
