Time Travel: Think It's Even Possible?

If time travel is one day possible, it would be ridiculously far into the future and we would all be limited in how far we can travel. To time travel, you would need to be able to

1) record every facet of the universe every moment of existence and store it all in the absolute largest database ever in existence to rerun it later when someone ultimately decides to time travel. And if we would have this capability, then this could be absolutely abused in war and easily lead to world domination, so it would probably never land to the general public.

2) save a "snippet" of the universe. This means every single organism's brains and well-being would have to be recorded, so that we can time travel back to this "snippet" where life can then continue from then on out as usual, due to brain functionality and health conditions playing out as it would have many years ago.

And honestly, more stuff that would take more paragraphs to explain. And I don't see traveling into the future will be possible, as nothing can record the future if it hasn't happened yet. The only way we could travel into the future would be if we were traveling from the past or if there really are multiple realities in different timelines that can be "grabbed", but there is no proof of that :/

As far as we know, there's only the here and now. It's all very unlikely, as we probably would have already seen some crazy shit happen to us in today's time due to someone in the future having come to us with some crazy tech. The fact that the future may be infinite and we have yet to have even one visitor from the future fuck up and give us anything tells me that time travel will probably never be attainable in the way we see in movies.
