    I seen TV shows where you try to change history. Like the Twilight zone. An episode this guy tried to warn authorities John Wilkes Boothe is gonna kill Lincoln. The cops laughed at him and say the actor John Wilkes Boothe is gonna kill Lincoln? So they arrested the guy for disorderly conduct. Not boothe the guy was warning them. He stayed 2 days in jail and then when Lincoln died they released him told him we should have taken you seriously and he told the cops were boothe was hiding they took him seriously and gotand killed boothe. And then he took a travel to 1939 in Nazi Germany he tried to kill Hitler but there was an Hotel clerk alerted the German authorities and they arrested the guy who tried to kill Hitler. And then he traveled to 1945 warn the Japanese about the Atomic Bomb is gonna kill everybody here. They laughed at him and arrested him then a day later Bomb exploded. Then on Quantum Leap Sam was trying change history prevented Oswald killing JFK but he was unsuccessful at that. You can travel back in time and enjoy it but if you try to change anything you ether gonna get laughed at put in jail and it happens or someone or something will be standing in the way preventing you from changing it. Like I wanna help the South win the war. So America would probably be a better country than it is now.

    He could have time traveled a 2nd time I wonder and made sure he got his point across!!

    Yes you can change history but it might not be good doing so!! (As seen in BTTF for example)

    If anyone changed history, how would we ever know?

    We wouldn't, of course. Change the past, and the past we remember is the new past.

    Here's how it really works: Time is like a video saved on a hard drive and playing in real time. The entire video is there, past, present, future, but we only see what is playing at the moment.

    If we go back and change something in the video, then save it, there will be two videos, one with the change and one without.

    Say someone went back and warned Kennedy, and his secret service prevented his assassination. Now, there are two realities, one in which Kennedy was killed, and one in which he wasn't.

    How do I know all this?

    Wild speculation and science fiction, of course.

    You can’t actually go back in time because it’s already happened and you weren’t there.

    That moment exists in time and it’s impossible to turn something into nothing.

    So it’s believed that if you could even access the timeline that you could Never enter it.

    You also can’t go forward in time since it hasn’t happened yet.

    Some believe that you could go back and start a secondary timeline but that’s just conjecture

    If time is the fourth dimension, why can't we travel through it? We can travel in the other three dimensions with no problem. Saying you can't go to 1850 because you weren't there is like saying you can't go to Acapulco because you've never been there before.

    You can never go to Acapulco the way it is right now only how it is when you arrive.

    Think of it like this, if it’s possible to go back in time that means there is something going back because the way is open whether it’s particles or light or gravity or something.

    Now anytime you add anything to something it forever changes things even if it’s only an atom the repercussions are endlessly different then what we have today.

    What this means is that that moment in time would get stuck in a continual loop because the future is always changing because there is always something going to the past.

    It’s one of the many paradoxes with time.

    You also assume this fourth dimension is sealed off from the other three which would make no sense since the three we know all exist just fine with each other.

    Basically time cannot go forward if you keep resetting it which means that if you could go back in time then you would never exist to go back in the first place.

    Now we know that time exists but it’s not something you can travel to because it exists right where you are right now, you just can’t access it because once you do you have changed things which means you’ve made that accessible point no longer the same you just went through.

    The only way of going back would be if you created another timeline on top of the original which means that every moment since you went back would continually be turning every single moment into infinite timelines.

    Now we don’t know what the universe can hold but there has to be a limit somewhere so infinite timelines are simply not possible unless there are physics we have not discovered yet.

    But for our understanding of science right now time travel is impossible even in theory. You won’t find a scientist in the world who has ever shown that mathematically it would be possible.

    It must not be possible, or we would have had time travelers from the future coming here. It's fun to think about, though.
