Jessica Meuse was robbed.

Well you would cease to exist if your Grandfather and Grandmother haven't had your parent yet.

All hail the Moyesiah

Didn't Futurama solve this one a few years ago, you just have to sleep with your Grandmother to ensure that you still exist

If you went back in time it would be a different universe. so it's true that you would never be born in that timeline, but it wouldn't affect the timeline you came from at all. There are tons of different parallel universes and timelines.

I think it may one day be possible to travel in time into the future when we have the tech to travel fast enough.Traveling back in time though i highly highly highly doubt could be done ever.

Ahh the grandfather paradox. "But if you never existed then you didn't kill him, so he lived, so you do exist, so you could kill him."
There are really only three options here: #1 Multiverse theory. This is essentially how "Terminator time travel" works according to the most recent, most crappy film and many other Sci fi stories. Basically, each decision creates a new timeline but doesn't erase the old one. So, you in timeline A go back and kill your grandfather in timeline A, creating timeline B where everything is different. However, timeline A still exists in parallel and so you (being from timeline A) still exist. This is the least problematic time travel variation. Option #2 The future is erased as soon as you travel back. Nothing past the point of arrival ever happened and you and anything you brought back are now an "anomaly". Your actions now create the new future. Killing your grandfather doesn't do anything, because that future is gone but you are still "from there". Sort of like a copy and paste, I suppose. Option #3 Time travel is impossible because, if it were possible, it would be happening constantly (because infinity) meaning that there is no such thing as reality at all. Reality would be in a blender. Option #4 the grandfather paradox is alive and well but no one has discovered time travel YET. As soon as someone does, they go back in time, any tiny change they make disrupts the future (doesn't need to be as severe as killing an ancestor - the butterfly effect suggests that a no number of tiny alterations might stop you from existing, stop time travel being invented, change future motivations etc.) and then the paradox activates and the universe implodes from that point onwards. Luckily, the first person to discover it didn't travel back as far as 2015 in human years. Last edited by Toy Soldier; 11-10-2015 at 09:08 AM. |

But there's no way to ever go back to the past before humans, or to any time in the past before that machine existed.

Well, since he is my father´s father, if he is killed, my father wouldn´t exist, meaning i probably wouldn´t exist either.

Surely that's hypothetically possible through cryo though? If it's "perfect". You freeze yourself, the world goes on as normal around you for however long, then in 200 years someone wakes you up. You're the same age as you were, you were unaware of the passage of time so you feel like you were only asleep for minutes. Isn't that effectively "time travelling to the future"? And as above, you obviously can't go back.

Maybe as TS said.Your grandfather still does exist because by traveling through time you have just created an alternate reality?

What if the time machine has a glitch and you end up just constantly being taken back in time just a split second like when a CD get's stuck and starts making that annoying sound... does that mean you can live forever?... the same split second for all eternity.

Yes but there's no obvious difference between the two for the "traveller", so would that matter? Let's say "jumping forward" in a time machine costs ten times as much as freezing yourself for the same amount of time... Would there be any reason to do it the more expensive way?

The "time travel" in interstellar is (effectively) the same principle... The characters don't travel through time more quickly than anyone else, everyone else just keeps aging and time moves on around them while they are "frozen" (moving very, very slowly in relativity to those outside the time distortion)

There really is no 'right' time in the universe is there?Everything in the universe travels at its own time frame depending on the speed it's traveling.If an object is in close proximity to another object(like us to the sun and the sun to the galaxy) etc then it travels faster due to its orbit and the faster an object travels then the slower time around it goes.Is that right?That's my basic understanding.
Also add on top of that the fact that everything is traveling through space.The galaxy's etc which also has an effect on time. Time really is relative. Last edited by Northern Monkey; 11-10-2015 at 10:03 AM. |
