Time travel to the past, your thoughts?

Beyond "not possible". The subject always fascinates me. I can't be the only one who has tried to imagine how it would work. So when you think about it, how does it work in your head? What makes the most sense (as much as time travel to the past could make sense anyways).
Let's say a scientist loses his wife, and then spends the next 20 years creating a time machine to go back and stop it from happening, and he actually succeeds. Does he just vanish the second the event that caused him to go back in the first place was prevented? Does he jump back on his time machine and go back to "his time" to find a completely altered time line? Does time just continually correct itself to keep in line with the the plan that has already been decided?
What about when you watch someone else jump back to alter things? Do the two time lines just run at the same time (if it took him 8 hours to change something you'd only see the change 8 hours later) or does everything change the very second he goes back? Does he have to set the events in motion to create the time machine in the first place since he's altering history and it would likely never be invented for him to go back in the first place?
Can there really be two "yous"? Is it some kind of closed loop that was dictated by time long ago? Or does the "past" end up with an infinite number of "yous". Does everything just fall apart because all the "yous" can't be contained? Surely if someone saw this they'd seek the original old time line you and tell them not to invent it in the first place. But then again, what happens when you deliver that message and assuming it was taken to heart?
Hard to wrap my head around it sometimes. The only thing that makes it make sense for me (which isn't even really time travel) is if there really were an infinite number of verses where every combination of events exists somewhere. You're not really going back in time, you're just jumping to another verse that is exactly the same as your past, only the past you, through some inexplicable event, ceased to exist the very second you went back. Then jumping forward to your "present" where only that one event is changed and yet again, the original you just ceased to exist that second.

yeah for me time travel only makes sense if time is like a pie, and each slice is its own universe, but different period. this resolves paradoxes. If you were to time travel through the slice your in it would probably fuck the slice up and no one would want to eat it and it would be thrown away because it looks unappetizing.

Think of the lucerative trips you could make. You could be rich in no time at all.
I would prefer to have the ability to instantly travel from one spot on the world to another. Oh my God how awesome my life would be.

yah see if time travel existed and you managed to go back in time, then every time the past "caught up" to the future, you'd have ANOTHER one of you go back into the past until the world was filled with you and then you started teleporting inside of your own body, unless that happens on the 2nd time.
anyone know what happens if 2 people travel back in time to the exact same time and spot?
is it possible stars use time travel to harness energy? How else could they burn for billions of years with nothing to fuel them and surrounded by freezing space that should have cooled them down by now to an ice ball.
you have to travel faster than light to time travel supposedly, so during the big bang, maybe there was so much energy thats what happened, the atoms during the explosion traveled faster than light then traveled in time to the start of the big bang adding more fuel, and that is why the universe is still expanding and why stars are still burning

Faster than light travel only facilitates time travel to the future. But you don't really have to have to do that to travel into the "future" all you really need to do is just achieve a good percentage of it (to get anything noticeable anyways). I don't remember the actual numbers off the top of my head, but it's something like "spend a year traveling at 70-90% the speed of light and then come back to Earth, 10 years will have passed".
Travel to the future is easy, it's backwards that poses the real problem.

I also used to be a time traveller.
Be out and about and suddenly waking up in bed in the morning with brain pains.
It takes a lot of power to time travel.

You're thinking about time in a linear way. As we perceive it, it seems to be. But if you can punch a hole through space(black hole, worm hole ect) you could theoretically travel into a different point in time and space.
Wormholes work in a way by folding space and connecting two separate areas seemingly far away, together. With time you could do it with the same concept, by punching a hole in the universe to connect two different points in time.
But also do you know what gravitational time Dilatation is? It's pretty much the heavier a gravitational pull is, the slower time moves, while farther away from a large source of gravity, time moves much quicker. If you were to be far from any body in space, then time would go much faster for you then say earth. If you were to be sucked in a black hole, time would nearly stop as you fell into it.

wait how does that work? in the case of the big bang, the universe around it wouldn't have even existed yet. alot of things in space get faster the longer it travels, so think back to the big bang and when shit went flying, that means the first thing that went shooting out was faster than light speed and most likely kept getting faster, and traveling further into the future faster and faster.
then the question becomes, what is the future really? here on earth that means older and things changing, but to the first thing that blasted off during the big bang, that doesn't really mean change since whereever its going is empty, and its not ageing because it keeps going faster? i dunno i don't get this space thing, what made the sun and earth stop here, why didn't it just keep blasting away? if the universe goes on forever then why didn't shit keep flying like cray cray towards forever? the beginning was just gas right, which turned to fire so at the start its not even like shit was going to be bumping each other, just at the small atomic level, so spread out evenly, in a big wave. then eventually would cool down and i guess somehow gas makes rocks so then things might start hitting each other a bit more violent but again space goes forever so they all just go their seperate ways right, so how could things ever stop and create solar systems?

 This is great.
Stars are like a giant nuclear reactor, they produce nuclear energy by 'burning' hydrogen to create helium, not burning from nothing. Big Boy converted under a (kilo? can't find reliable sources of the mass) of nuclear mass into energy to completely flatten Hiroshima, equivalent to 15 kilotons of TNT. Regardless, imagine the size of those sun's and the amount of mass they carry, and there's your answer as to how they burn for so long.
For the record, time is proven to be relative to your frame of reference, not absolute. Once you travel at speeds close to light, even half the speed, is when the implications of special relativity are shown, which are length contraction, mass dilation and time dilation. The closer you get to the speed of light the larger the effects of special relativity are.
edit: nothing can travel faster than the speed of light either, also a result of special relativity

so really time is just big bang = 0, and whereever your from the big bang = 0 + the distance? in other words time basically just boils down to how far away you are from the big bang starting point?

Yes I know about time dilation. But that is still only forward. Time for you slows while everything else keeps moving at it's normal pace.
But for the rest, how would that work? Say you punched a hole between "now" and a year ago. Are there multiple yous? Does the traveling back just keep happening resulting in infinite yous being in the past? Do you just take over the former you's body? Is it a closed fixed loop where in that past there was always that future you and the cycle just keeps repeating itself? Did it always happen and will always keep happening?Quote:

Everything is relative. I get what you're asking, but I dunno if there is a way to really study the implications. Everything in a practical monitoring distance to us is moving at relatively the same speed, so it would be hard to find any distinguishing and obvious issues. At the far fringes of space, maybe (and I use that term loosely). I'm not sure at what speed the shit near the fringes is really traveling compared to us or any steady center point. To really start noticing differences, you have to go extremely fast. Fast enough that we may never even be able to achieve it and fast enough that universe may not even be expanding that fast.

you say stars burn so long because they have so much mass, but you forget that they are burning much more mass at the same time. Our nuclear plants last like 10 years then they have to add more fuel rods maybe its even less than that, but we run them alot cooler too, the sun burns way way way hotter, and remember we are talking billionsssssssssssssssssssssssssss of years. meanwhile look at what we are doing here on earth to fuel these nuclear plants, we gotta dig dig dig to find the right shit, but somehow the stars are full of the shit, purely exactly whats needed to fuel it?
doesn't it seem odd that its so hard for us to replicate the sun, and the sun does it so perfectly for billions of years? and then the entire sky is filled with teh same thing over and over again, mocking human kind, saying look free energy everywhere and you can't have it nor create it

Time is just how a certain point in space flows. As you go faster, so does time. If your closer to a heavy gravitational pull, time slows down. Farther away, and time speeds up.
Time and space are a single thing. They both weigh upon eachother.
Quote:

Well not exactly, but kind of. When the big bang happened, all matter was in a single point in space, so time didn't exist. But as the big bang happened, both time and space were created instantaneously. The universe grew and the gravitational pull of all matter scattered, and eventually gravity started pulling matter together, creating the objects in space.
But theoretically, time would slowly speed up as the universe expands and matter goes farther and farther away from other matter.
But really time only exists because gravity pulls at the fabric of space.

and we still don't know what gravity truely is yet right? so time = gravity that pulls on space fabric
so T=S-G T+G=S+G nvm i havn't done aljabra forever i was goin places then gravity fucked it up

I'm very hesitant to agree with this. It wouldn't be the first time we thought we had it all figured out only to discover we didn't. Just as in the past, there is still a lot we don't understand and are working to try and understand. At best, that theory just seems likely given the evidence and what we have discovered thus far. Until we have a model to explain every last thing in the Universe, nothing is an absolute. No matter how much sense it makes.
As makaveli just said above, we don't even know what gravity is. We just understand it's effects and can calculate it.

@shroomslip IMO, you have to think about time like an ever branching tree(or mycelium ) with each decision or possibility happening creating a seperate timeline where that happens. This can be anywhere from the physical changes of our planet to the everyday life of you.(pretty sure it's called the multiverse theory)
To time travel with this theory, you would jump back to a point in the timeline you live in, and any change you cause would create another timeline where the change you made effects that worlds timeline. Causing the butterfly effect. Time paradoxes would be impossible with this theory, as you create another timeline.
But the real problem is traveling back. Are you going to be able to travel back to your timeline where you never went back in time, or are you going to travel to the new timeline that you created by traveling back in time.

yah and with those little things being in more than 1 place at the same time, and just looking at them affects their behavior, some sneaky magic shit going on and it seems like one possible explaination for that (like being in 2 places at once) could only be explained by either being faster than light, or bending space and time. but how could something so small be smart enough to do it just because we looked at it?
