Look at me, I am making a "smart" blog. Oh wait, just saying that has made it a dumb blog. Anyway…
Time Travel Paradoxes and stuff:Everyone likes thinking about time travel right? How you could go fix the past, check out history, and see the future. But there's always the problem of paradoxes, the whole "whoops I just killed my parents" type thing. There are lots of solutions to this problem, ranging from not being able to time travel before the time travel machine was invented (creating a "check point" in time, just to make a gaming reference) however thats not too useful is it. Or that time travel actually sends you to the past in a parallel dimension. Whatever, I think it would be too hard to find a parallel dimension enough like our own. Then people say when you time travel changes might be immediate so you never even remember changing time, wouldn't it suck if you completely ruined your life and didn't even know it. But if it didn't work like that and you remembered everything then any small changes in the time line would do a butterfly affect and make it so everyone you know is different than you remember. So in the end time travel pretty much completely sucks if its to the past, but what about the future? It would be pretty cool to go grab some technology from the future and take it back with you, but this causes paradoxes in some ideas of time travel. Plus if you can time travel theres probably gonna be someone in the future stopping people from messing up the time line, assuming that since earth isn't full of time travelers there must be some rule or police keeping them away from our time. This would work in the dimensions theory though, so if thats how it works then someone needs to hurry up and bring us back some hover cars.I've been writing a story for about 4 years now and it has time travel in it so I thought I would share how time travel works in my story. I went with an approach that you can change the future but the past is pretty much set. You can go to the past, but thats already happened so it doesn't change anything in the future. it's only when you go to the future that you can return to the present and change something. So what about paradoxes huh? What if someone sent a bomb back in time. Well the way I'm thinking is that if a paradox did happen then time would repeat itself over and over in a loop until it didn't happen. So in my story the past is set because time has gone through loops until no paradoxes are left allowing all time travel to have already happened (since changing something important would cause changes in your past causing you to be acting on things in your life that no longer happened the same way, which is a paradox). Some people say things in the universe have a random element to them, that it's not all just action-reaction. Kinda the idea behind some parallel dimension theories. So basically in my stories time would repeat until that random element caused it not to happen. Then things would continue on like normal.To be honest I find the one where you cant travel before you invented the machine the most likely one to be possible, but that would limit my story =p
If you traveled back to before you created the time machine, would you not be bring this machine with you? And so you are modifying the past. By that theory, people would be infinitely traveling back before you modified time and bringing their machine back, and would continue dong so infinitely. As such, to us, we would have our time modified immediately, by someone coming back in a timemachine, to try and fix a mistake they made in the near-future of revealing their time machine.
So the fact that no one has yet came to our time in the "past" with a time machine, proves the theory that "you can go back in time to a point before a time machine was created to fix everything", must be false.Yeah?In some theories, yes.
You don't even know what I said.
By going back in time, just like when you make any decision, you create a unique reality. Theoretically.
Time travel is impossible because nothing can travel the speed of light, and worm holes do not exist. The fabric of spacetime cannot be torn, so worm holes cannot be created either.
If you watch Lost you know that there could be another kind of time travel where no matter is involved: traveling through time with your mind. The producers of Lost even found a way to get around paradoxes: amnesia.
I dont believe we could survive time travel.
We would die!!!the only way to "travel" faster than light is to bend space which would in a sense be teleportation.The problem with time travel, is that even if you do manage to travel in time, you are staying in the same position in space, so who knows where you will end up!
