Time Travel Theories.... Think about them carefully. A time Travel Machine could not be built because if it had then people form the future would have already visited us. However it would not be possible to travel backwards in a time machine before the machine was built as time travel wouldn't exist. So if we wanted to go back in time now our only hope would be that other civilisations in the universe had already mastered time travel so we could go back in their machine. Just a few thinks for you too think about, very complex physcis.
Kind of an intense topic, I dont want to get too into it, but look up wormholes and general reletivity theory.
But what if they invented time travel and never used it. What if some people are traveling in time and they are the ones who are pulling the string.
how can you of invented a time machine which noone uses but there are people using it? that makes no sense
Your first and second statements contradict each other. If it's not possible to travel backwards in time before the machine was build, wouldn't that explain why people from the future have not visited us???
why can't you travel to a time before time travel was invented? time has always existed, there just isn't the mechanism to control it.
Eh, I've never been much of a believer in time machines that take you far into the past/future - but I have always seen crossing time zones as a sort of time travel. Like if you flew from England to California, you would be going backwards in time by several hours. Not sure if that really counts though.
but if someone went back to before the time machine was invented then people from the future would already have come back and met us!
No i didn't say that, If you could travel back in time, then people from the future would already have travelled back to our age to see our generation of people.
Buffy got the idea. If future people were coming back (and why would they? we have recordings of everything there wouldn't be a need to) why would they show up on the news? they might visit specific important people, or watch certain events happening, but regular joes wouldn't know.
Thats the idea of parralel universes, when you go back in time, you CAN'T change the past, even if you killed a world leader then it wouldn't affect the future you came from.
Not really, a machine could of been made, but then they broke it. Also, time travel is meant to be a fourth dimension, using worm holes in space, which may or may not be there. By using these holes, your physical form stays the same, so does your machine. Or that's atleast what the nutty professor said...
i suppose thats sort of true, if you look at the sun you see it a few years ago, and the light thats travelled from the sun is from the past because it takes so long to get here, when we look at the sun we are sort of looking back in time.
In that case, what's the point? If I can't go back in time and kill Hitler, what would be the point of going back??
I hope you're not talking about our sun. Light from our sun only takes about 8 minutes to get to earth.
