There's no way to know anything about time travel until we do it

I'm actually really against time traveling. Butterfly Effect and A Sound of Thunder.

if time travel existed, we'd know about it surely, cause there'd be a bunch of quantum tourist ***** going about being all "woooooooow! big ben was so amazing before it was destroyed in the great fish n chips uprising of 2419"

Time travel will does not exist and never will, but lets say it does then heres just one example of what can go wrong.
You time travel say 1000 years into the past, theirs diseases that your body isn't used to so you'd die very quickly, you can't just whip up a vaccine.
If you go back in time then you'd be at your location in the universe, which would be in space by then.

actually our body contains a catalog of antibodies to ancient diseases that we would never come in contact with so we actually wouldnt become that ill

Doesn't some theory say amount of energy in the universe is constant? (including energy from E=Mc^2)
So how does it work if you send matter into the past/future?
User avatar #44 to #35 - mooproxy (06/21/2014) [-]
I'm far from an expert on this sort of thing, but I may be able to help:
Conservation of energy is accurate, and e=mc^2 ties in when you're converting between mass and energy, but it gets a bit hazy in the quantum area, for example vacuum fluctuations - particles can appear from nowhere and exist for a time inversely proportional to their mass until they cease to exist (even then for a very, very short time), but while they're in existence, there's a very tiny bit more energy in the universe than there was before.
The concept of time travel is also a bit fuzzy on the quantum scale, as I think there's no mathematical difference between, say, an electron travelling forwards in time and an anti-electron travelling backwards in time.
Also, relativity dictates that the closer to the speed of light a particle travels, the more slowly time pass 'from its point of view' though if we extend this to photons (which of course travel at the speed of light) then presumably time doesn't happen at all 'from their point of view', so a photon that starts in a far-off galaxy and collides with earth, while it'll travel many millions of light years, it wouldn't perceive any concept of time (if it could have a point of view).
I think this article involves projecting a photon along a path through spacetime without changing its spacial location, and since mathematically there's little difference between forwards and backwards in time (and photons don't have corresponding antiparticles) they somehow managed to persuade one to go backwards in time, though remember it's a simulation and not an experiment that has actually happened yet.
Remember of course, that I'm no expert on the matter, and I could be completely wrong. Time is always very difficult to understand when people are messing with it.

So... they created what they think would happen.

If time travel were possible, wouldn't time travellers already be here?
User avatar #55 to #53 - masterenclave (06/21/2014) [-]
yes they are. who else do think taught us time travel

Time travel will never exist because if it existed at any point then the entire timeline of human existence would know about it, surely?

Instead of being a douchebag who smokes weed and thinks science is cool, yet does nothing more to involve yourself in the science community but read a horrible interpretation of the paper in an article written by IFLS, try reading the actual paper. They don't leave anything out.
User avatar #109 to #104 - atomicman (06/21/2014) [-]
I agree. This article seems insanely non scientific. Also the entire picture does not make sense to me. Look at my comment #94

I need further explanation from someone who know's what he's talking about.

What this figure represents is(as far as I understand, correct if wrong):
->Horizontal 1/2/3 dimension(aka number 1) current
->Vertical 4th dimension(aka time or number 3)
->Horizontal 1/2/3 dimension(aka number 2) past
->3 unexplained dimension/twist in dimension I'd like explained

Light loops through a hole(please explain how they shaped one)in the 1/2/3 dimension which leads to the time dimension. Which it then again leaves in an earlier stage of our 1/2/3 dimension whereafter it returns to it's former dimension. How does this current work? Why does it return to it's former time?

Thank you smart man, You make the internet a better place.

Well, you still have to find a wormhole if they exist in space or make one if there isn't, and then you have to find a way to keep the wormhole open long enough to not crush whatever goes through it, not to mention the incredible radiation inside of it, and then the wormhole will have to open where you want it and not like inside a star or next to a black hole. Not to mention the infinite amount of time eras the wormhole will send you through.

This content deserves a general time travel thread. Any theories/time travelers out there?

I've been watching Fringe recently and have come to the conclusion that if we were to travel back in time it would be boring as **** .

Finally I will be able to travel back in time and steal money out of Hitler's wallet, because its the Reich thing to do.

Returns to the same location in time and space


I feel like this means that it has not moved through time or space...no time travel or directional travel.
