1. Could it ever be possible, or is it just a ridiculous concept?
2. What would you do if you could change the past?

You need to talk to John Titor

Sure, I time traveled while I was on Iboga. Sort of like getting to see things like a ghost, but not actually being able to do things in the different times.

Well, we already know how to travel forward in time -- get in a ship and come close to the speed of light. Outside the ship, time will "flow" more quickly than inside the ship (relatively speaking, both you inside the ship and everyone outside the ship would experience time flowing normally). The closer to the speed of light you get, the more pronounced the effect. So basically, going 99.99% the speed of light means you're traveling into the future.
But I take it you mean traveling backward in time. Well the last I read, nothing we know outright prevents this from being possible... and if you actually were able to go faster than the speed of light, you'd be able to arrive at your destination before you actually left -- so I guess maybe you could do something with that and just repeat a whole bunch...
I don't know; but if time is basically a fourth spatial dimension that we obviously experience very differently than the other 3, it can't be possible. I mean simply by virtue of traveling back in time, you would yourself travel back in time to the state you were in. As in, just like moving an object to the right of a table: the object moves to the right. You can't move it to the right and expect it to end up anywhere but right where it goes.
... I'm explaining this incredibly poorly. But basically, time travel is always paradoxical. You don't even need to consider the grandfather paradox, that's just a weird human concept: the paradox arises the very moment matter "pops into existence" in the past. It wasn't there originally. It'll displace molecules that will be in different positions. Without alternate dimensions, it's always a paradox.

Was not a poor explanation at all. So basically the paradox only occurs if you are speaking of going back in time? The traveling to the future part seems to be pretty clear cut to me!

Yes, that's the idea :)

You are awesome, SS ;)

I didn't have the power to save someone I loved very much the first time around, and I wouldn't have the power this time either... so that's no good. But I could fix all the mistakes I made over a very particular week; I wish I could live that one week again. I would have liked to see where life took me if I hadn't been quite so stupid and so drugged for those days...
I think it would have been a good path to walk.

Mrs. Sparrow says you can do it.
But you can't change the past. If you did, you'd branch out into an alternate universe/timeline, to avoid unpleasant paradoxes.

you cannot undo the past. even if you stood in the 'past' it would still be the present/ future of now because thats just how the human mind works. if it didn't work that way you wouldn't know you;d traveled back in time.
however the physics of it seems to be that you cant go back in time, fate is reality, intelligent design is correct , black holes were placed stratigically to maintain some form of balence and to stand as reminders and that black holes are actually gateways , probably to other dimensions and maybe in some way to heaven. this is speculation , not me stating theory as fact (not that you should get so upset at something that you try to say is so obviously nonesense- you dont rage when I say I tangoed with a purple penguine)
if I could go back in time Id run away to the town my beloved lives in , save her from the trauma she went through and grow up with her and make sure she never met her fiance. . also I'd write the script to butterfly effect just to be able to have a chuckle at the universes sense of humor.

Wouldn't that be quantum mechanics and the multiverse theory? But to come back to your earlier explanation of time traveling, wouldn't traveling along the edges of the universe grant an amplified effect of traveling forward in time? And then there are the theorized wormholes, where traveling through them would either pull your forward or back in time (To a specific point, not unlimited time travel) depending on the direction you travel in, along with a huge distance covered as the two planes fold over each other where the wormhole would act as a shortcut.
To tedrux: Black holes are not wormholes.

yes they are. you cant know otherwise.

I would buy 100.000 Bitcoins @ 0.07$!!!
yep!

yep!
By buying them, you would alter the future, and they would devalue to 0.0000001$ !!! And all the other people hopping on the timetrain to also buy them at 0.07$ ... oh dear.
yes they are. you cant know otherwise.
https://en.wikipedia.org/wiki/Wormhole Not all black holes are wormholes.

ooooooooooooooooooh. OOOOOOOOOOOKKKKKKKKKK Wikipeeeeediaaaa's your source....Well EXCUSE MY INSOLENCE lol. look dude, till your in the heart of a black hole you dont know shit. also, due to the nature of knowledge, even then you don't know shit. tough brake kid.

Space and time can bend.
Or you can FE for my time machine. Only two available.

Hey man, thats a good idea.
Just throw 2mil$ my way and u are the first to pre-order a timemachine. Delivery not before year 2198.
Thats about what butterflylabs must have been thinking...

BFL didn't even have an ASIC developed produced when they were accepting money. They had an idea and used all of that money to fund development and production. If you can figure out how to make a working time machine then you could do the same thing.

No, I was referring to something very specific. Had nothing to do with physics. Just some irrational mistakes I made during an important week. I shouldn't have been so fucked up... drugs aren't always good. Some people seem to forget that -- I certainly did that week.
Yeah, I don't know much about what you're referring to... but you're right, I do remember some theories about wormholes that end at specific points in time. I really can't comment on that, I just don't remember anything I've read about them. The problem with worm holes is that they depend on absolute symmetry. By approaching one side of a worm hole, you disrupt that symmetry and the worm hole would collapse (so I read). That doesn't mean it's impossible, but it's certainly a tricky problem.
I will say that no, I don't believe traveling at the edge of the universe would increase the time dilation effect. Although that kind of depends on what you're talking about, I mean the rest of the universe isn't in a single inertial reference frame -- everything is moving relative to everything else, soooo... I dunno, maybe it would increase the effect with respect to some reference frames but not others. That would only be because the difference in velocities would be even greater though, I think. I'm not sure. Frankly my brain kind of starts boggling when I try to think of the entire universe while factoring in relativity like that :P
Time dilation also happens with extreme gravity. Same phenomenon. So here's a question for you people that I've never been able to come to a satisfactory conclusion about: what happens if you try to pull someone that's right outside a black hole (not past the event horizon) back out with a rope?
What would happen? As you approach the black hole, time dilation becomes more and more extreme. The different parts of the rope are going to be experiencing time dilation at different rates. So the part nearest the black hole is going to be moving unbelievably slowly compared to the part way, way out where you've got somebody pulling on it (pretend it's Hercules pulling some unbreakable rope or something, whatever). But the part of the rope way, way out where you're pulling it is going to be moving very quickly in time as you pull it relative to the part the guy close to the black hole is holding on to.
... so wtf happens as you pull the thing? I've never been able to figure it out. I suspect my problem is that I'm trying to fit time dilation into some modified intuitive sense of absolute time, and that there really isn't any paradox at all because there is no absolute time... but I've never really been sure.

:o that was actually pretty well explained.. at least for simpletons like myself :P
thanks for sharing that..

The rope would look as if it were being "stretched", just like all the other objects, when observed from the outside. It only just looks very distorted because of the different speeds of progression of time, depending on which side you observe it from.

Actually I was referring to what would happen to the rope sections themselves. Since time is moving more slowly toward the black hole, pulling the rope from far out would... snap the rope? Behave as normal? The problem I have is making sense of what would be happening at both ends of the rope "simultaneously." I really think it's just an issue with my conception of the situation: there is no absolute time... so time could flow normally at all points on the rope, even though comparatively it's flowing faster far out than it is toward the black hole, without there being any actual contradiction. I think, LOL?
It's just... fucking weird. How can time flow faster toward the guy pulling the rope, and still have that coincide with it moving more slowly toward the black hole? It just seems like the rope would break or... something. The section toward the guy pulling would be moving faster than the section toward the black hole, and yet... I mean you can't magically create more rope to fill in the space as you pull it apart, so... well I really just don't know. I've always had a great deal of difficulty really deciding what would happen.
