So I'd like to travel in time but lack any grounding in physics etc
I've been doing some research on the internets and wondering if I should take some courses at uni or something

Unless someone discovers a way to warp space-time without having to use astronomical sums of matter, then time-travel is impossible. You can slow time by accelerating to high speeds then coming back to earth, but that's about it.

if your hand speed can reach 88mph while yanking your dick, you will be able to travel to any point in time
travelling back to time is extremely difficult to do
it is much easier to just change everything around you to a previous time than you actually going to the past

Create a spherical shell shaped blackhole around you, somehow find a way to control where the complete seperation between the two areas (you being in the one inside the field) take the one you're in, good luck.

You can't travel "back" in time. Time is an illusion, much like the frames of animation trick you into believing there is motion. All you can do is observe short sequences of time-like intervals.
Time is created from out inability to percieve everything at once.

Time is the effect of the universe moving from one state to the next, in order of increasing entropy. Physical laws dictate how the states change. These states exist for the duration of one quantum of time.

I've been there, give it up. We are not living in an anime or computer game, this is real life, sorry.
I just made up that idea of time a little while ago. There are some ideas in modern physics that both space and time might be quantized, though.

you have ridiculously short attention spans. threads peak when they get 2 replies and it's over. why is it so hard to have some proper discussion? one word replies are not fufilling. lounge has great potential as a discussion forum and i know there are intelligent people here, but they are wasted.

I can understand travelling to future using speed of light, but seriously I can't understand how do you travel to past? I mean that past has to be somewhere? Does someone honestly believe every second of our time is stored in some alternate dimensions?

question, wouldn't time travel into the past violate the law of conservation of mass/energy? since, for example, you from the present goes back to the past, the matter of your body now exists in the past where it was'nt before. or is there some resolution to this.

Space is quantized dipshit, gb2/thermodynamics/. The entire derivation of entropy relies on the Planck length, a quantum of space.
As for time, it's probably not quantized, because it's conjugate to energy which is probably not quantized (and before you know-it-all physics first years get your panties in a knot, read carefully you little shits, energy comes in quanta but there is no fundamental unit of which all energies are an integer multiple; the spectrum is continuous.)

Time travel violates many laws of physics, conservation of energy being a relatively minor violation compared to causality.
Why sage?

It's not a quantum, it's a natural unit, dumbshit.
the spectrum is continuous
WTF? Maybe in our current descriptions of the universe, but those are only an approximation. We might discover quanta when we look deeper.
Jesus Fucking Christ.

I did say "probably" for this reason, that as far as we can tell, it's continous. And I called the Planck length a quantum of space because you can't measure anything to within a Planck length. It's impossible. That's why when you build the distribution of states in any thermodynamic system, you break the phase space down into a grid the size of a planck length and its momentum conjugate; you 'quantize' the space. Saying a quantum of space is correct in this sense, dumbshit.

Obviously you can arbitrarily quantize things, and the Planck scale is a nice basis. That doesn't mean space is actually quantized at the Planck level though (although the two are probably related by a rational factor, maybe even an integer).
1. Invent Stasis pod
2. Sleep in Stasis pod
3. Wake up in the far future
4. Ask scholars there how to travel back in time
5. If #4 doesn't work return to Stasis pod and repreat step #1
6. If scholars in step #4 knows how to travel back in time then,
7. PROFIT!

Original Poster here are my suggestions regarding Time travel:
Time travelling to the past can actually done by humans when they reminisce the past. Its a mental form of time travel that does not include the physical body. When you go to the past via memory too bad you can't change it for it has already happened.
To travel to the future I would agree with '>>31' and use suspended animation (aka 'deep sleep') to send the time traveller into the future.

well its fundamentally impossible to travel faster than light speed...or even travel at light speed. Besides that It is impossible to travel back in time for this simple reason.....IF you traveled back in time, you would alter the future, if you alter the future then it is possible that the changes would have stopped you from goin back in time in the first place. Eg. if you travel back in time and kill yourself, then you wouldnt exist to have traveled back in time in the first place, therefore how was time altered.....= end of universe.
It is not possible to travel back in time and perform an action which would prevent you from travelling back in time.

ZOMG if you travel 1 day back in time won't you appear in outer space coz earth is fuckin moving around the sun and the whole fucking galaxy is probably fucking moving too explain me this einstein.

For the last time those who believe it's possible to travel back in time should explain where the past they intend to travel is. Do they think that every second of our time is stored in some parallel dimensions or something like that? I asked this before, but didn't get any reliable answer. I'm no physicist and quantum physics makes my head hurt, so perhaps someone could explain it clearly?

It's very possible to do this in the very near future.
Mark my words, by 2075 we'll be starting up uni's for time travel.

It's possible to go forward in time, all you have to do is travel close to a black hole, I've heard; as you're pulled in by the black hole time will move slower for you. I can't remember exactly why though, for the life of me. Sail away from the black hole, and you've jaunted forward in time.
We'd need a spaceship that can survive this though.
Going back in time is impossible as far as I can see.

You need a body that can survive spaghettification aswell.
Assuming only one's fourth dimensional position changes (i.e. the first three remain constant), try to use 365.26 day intervals... and hope no one is standing in the way.
>>47 depends on the radius of the black hole (by that I mean the event horizon). There are lots of ways to travel forward in time faster, such as cryo, using speed or gravity in your favour, etc. Going backwards in time hasn't been proven impossible as such, but it's very unlikely it is possible, and if it is, that anyone will be able to survive something like that.

in string theory time is the 4th dimension (with x,y,z being the first 3). and in string theory there are 10 dimensions each ontop of the others. if you could move your self around in the 5th dimension then you could move to from any point in the 4th dimension(time) to another point without going throw the points inbetween.
If you went up to the 10th dimension then what you would see is everything that is(the universe now), was(the universe in the past), will be(the universe in the future), could have been(everything that could have happened in the past), could be(everything that could happen in the future) AND everything that is impossible and could never have happened or will happen. and all this would be in 1 infinantly small dot.
>>52
SPOILER: String theory is bullshit. But even if it weren't, the extra dimensions are supposed to be all rolled up and invisibly small, so they have nothing to do with parallel universes or whatever you fuck you're trying to say. Yes, the whole theory may be bullshit, but that's no reason to just start making stuff up about it.

SPOILER: Spoilers can only consist of 1 fact.
That is *NOT* how higher dimensions work in string theory. Current superstring theories have 13 dimensions, not 10, and they are PHYSICAL dimensions. Like left/right, up/down, forward/backward, etc/etc, etc/etc... None of this "imagine all possible 3D states", or "imagine an infinity of infinities"... That's so completely not how higher dimensions work! AAARGHH
>>56
Sounds like bullshit. It would explain certain anomalies, but regardless I find it hard to believe. I mean it's just absurd and on same level as crackpot pseudoscience theories.

Ugh, retard. There has never been and there will never be a string theory in 13 dimensions. The bosonic theory is 26 dimensional, and the supersymmetric theories are 10 dimensional (R^4 x M^6 where M^6 is some 6 dimensional Calabi-Yau manifold).
I don't think you can even have an odd dimensional string theory for various reasons (e.g. the hodge dual operator isn't an automorphism unless d=2n).
