Thread: Time Travel: Why I think multiple timelines are impossible.

(I know my ideas are purely phylosophical and contain no mathematic equations to back them up, but just listen to my reasons.)

I believe that in the subject of time travel multiple timelines are impossible as when we create a parallel timeline would that not violate the first law of Thermodynamics, as matter cannot be created or destroyed. In my eyes this would be the creation of a complete universe of matter.

Decide for yourselves if I am right and please tell me any consistencies in my hypothesis.

you are extrapolating the laws that apply within the universe to what lies beyond the universe.

but if energy is conserved beyond the univeres then where did all the energy come from to create our universe.
isnt it simpler to just assume that energy isnt conserved beyond our universe?

Well, the universe is believed to have no boundaries, like a balloon expanding, so I fail to see what is outside the universe?

In my opinion the universe is like a website full of minigames, no way to join two mini-games physically without altering the code, and these games work in their own allocated space with no in between to join them, and so there is no physical area outside the universe, just nothingness.

This does support parallel universes.

If we assume a universe exists for every possible path that history can take, and then add possibilities created by time travelers, then time travel massively increases the number of possible ways for history to go, so probably the vast majority of universes/realities would be based on timelines created by time travelers ..... which would make it unlikely for us to be living in one that was not created by a time traveler.

This makes sense, I have always believed in parallel universes of different possibilities but never looked at it in this light before, thanks.

But I dont believe time travellers made parallel worlds, as they would have no way of getting back, as well as having to count for all the different possibilities in existance?

The whole subject of time travel is paradoxial...

Time travelers do not create the parallel universe. When you are confronted with choices you create a split in universe.with each universe having a version of yourself,living a little differently as a result of the choice you made and did'nt make. Each of the other version lives as a though you said yes and another as though you said no.this becomes true for any choices.as you are confronted with options,there are split in the version of yourself. Check quantum theory,many world interpretation.

This is what I actually believe, but this thread was to disprove the idea of a time machine that could defy the laws of physics and leap out of the universe into the next, even though universes have no physical boundary.

Remember, space is actually a 4 dimensional area as when we observe a far off star light, with no influences is still bent, causing this theory.

If there's one timeline for every moment of time then there are infinite number of timelines!

As a matter of fact for you there are no other version of yourself,you cannot prove this.You do not meet,you cannot experince it,and in the other version of yourself,there is no you.To that version he is the only existing you. You do not have to shift universe. The universe are created without your awareness.All you have to do is to be confronted by options. E.G

If i ask, would you like to think that the moon is there even when you are not looking? In whatever answer you give,the moon fall into a superposition of being there and not there atsametime. According to many worlds interpretation,there are two universes with one possible reality. Which is the moon is there or not there. When you carry out the measurment,by looking,you shift or take one reality. The reality you now take does'nt make the other less real in the other universe.

A different dimension doesn't have mass inside our universe. As it is its own closed universe which we cannot communicate with. Neither can we observe it. No laws of thermodynamics are violated, but proving it is, well, problematic.

I really dont see the problem of proving it. There is nothing emperical to show it there is,its a full stop.
