    Time travel is possible we sleep every day and we see future after some hours for ex. like a man get in coma for 3 years when he get up he see that her daughter is married so for him that's a one day but it impossible to go at present I think so but I am sure we are living in two parallel world's with senses after death without senses.

    To me time is like jelly every time you take a bit there are cracks and as you keep eating the jelly slowly goes smaller and smaller until there's nothing left. TIME IS A VERY DANGEROUS THING

    Why do there have to be so many theories about black holes? Can't they just be as simple as they sound?
    And why wouldn't light experience time? I'm not knocking the theory I just wan't to know why people think this.

    …but…but, just by you being back in time does change it.

    Well we're basically travelling to the future now :3

    what is time?

    It is physically impossible to go back in time I have researched it.

    time travel is impossible because of energy. it may be mathematically possible  but not physically, because the energy required to travel back in time takes more energy than what the universe has. thats my view of time travel. and for split universe's. that is making an entirely new existence/universe which probably requires much more energy.

    So basically the last theory counters the butterfly effect?

    i think  that traveling back  in time and screwing up something wouldnt effect anything in the present is because, any times we might travel to are alternate universes 1 second or 1000000000 years behind us

    Man, quantum/parallel Universes - Multiverse theory is frustrating.  When people talk about it, they always mention how there's this universe we're in now, and in another universe you're the president, or a movie star, or ect…    It is just stated that there are infinite universes that exist.  The thing that bothers me is how we always concentrate on how the universe is different regarding us as people, and not, say the atoms that makeup our worlds.

    Basically what i'm saying is that, if multiverse is true, then there are also an infinite amount of universes where we are all living exactly as we are right now, except the atoms within a cubic meter of earth are just all slightly aligned differently.  So to say, there's not just "one universe where you're the president" but literally an infinite amount of universes where you're the president.

    I just prefer to think that the Multiverse theory is an anomoly that has shown up due to our limited understanding of the universe and physics using the current Maths available to us; and in time when our tools and methods are further refined, we may have some "parallel"-ness to it, but i'm not soo sure about "infinite"-ness.

    If time travel will be possible,then everything that is present today may change!
    If the time travel is invented right now then we could die! Imagine if after years when the time travel was invented there would be someone planning to kill your parents and you wouldn't exist.. That's why I'm telling you that Time Travel is DANGEROUS! Which means that Future can Affect Past,if in the future,you can convince the killer to stop then you will still leave,which means.. Our Ideas will affect the whole cycle of time!! Please scientists,don't create time travel

    Who wrote text for this top? Makes no sense.
    -How does an argument that light doesn't experience time leads to conclusion that someone don't experience time when traveling at speed of light? There is no connection in this kind of context.
    -How does using gravitional fields in a vaccum leads to time travel? Seems more like someone's random misconception about relativity's theory.
    -universe splitting constantly with a purpose of fixing time paradoxes? Seems like a troll's logic. Someone mut have overheated while speculating about time paradoxes and have thought - "screw this, infinite universes explains this".
    -"Some believe that quantum mechanics prevents changes in timeline" and added troll's conclusion to that "theory". Are you serious?

    Exotic matter? I mean seriously something with negative mass. Seriously.

    Its not like you wouldn't age if you moved at the speed of light. Well I mean it is but you can't reach the speed of light (see Einstein's theories to understand why) but assuming we could move at 99.9% of the speed of light, then we would age way slower than anything else would.
