[QUOTE=billeh!;22596664]if someone were to observe someone travelling at a higher speed or in an area where space-time is more compressed than the space-time where observer 1 is at, then time would appear to go slower for the traveler or observer 2.
meaning the faster you go the slower you age and when you're in deep space you age slower than when you're on earth.[/QUOTE]
That's still a measurment of physical reactions.
Unless I'm reading that incorrectly.
I think of it like two balls of play-doe
Traveling forward in time is like leaving the main ball in the open and putting the other ball (you) in a refrigerator. While the other ball hardens, you are in a sort of state of suspended existence.
However traveling backwards in time would be impossible.
[QUOTE=MrEndangered;22596674]Time reversal is a very heated matter for debate.
Going forward in time, however, has been proven, as once Russian astronaut technically is 0.02 seconds younger than when we left earth because of the time/gravity shift.[/QUOTE]
actually time reversal is probably impossible because in order to travel back in time you would need to exceed the speed of light, which would require an infinite amount of energy because an object would become 'infinitely massy' due to mass-energy equivalency.
however there are some theories related to wormholes that would result in a change in time when wormholing from one location to another but wormholes exist strictly on the blackboard for now.
Oh look another philosophy thread, i love to watch these, its like watching people fight over whether the grass is green or not.

[QUOTE=Willie Nelson;22596699]I do smoke mary j, but no I wasn't high when I made this. Also that movie is just a comedy so chill. Also I don't know what the fuck reality is, but I do know Albert Einstein invented it along with the string theory and other scientific shit. I am not trolling but on a serious note explain how we can only go forwards in time but not back. And if you go the speed of light you can go backwards, well why in hell is no one trying to go that fast. But does that mean light is in the past when we see it?[/QUOTE]
Albert Einstein invented General and Special Relativity, not the original theory of relativity, just fyi.
Faster Than Light travel means that those aboard a FTL spaceship will observe time differently to those observing it. Time will pass much slower for those outside the ship than those within it. So going 'forward' in time is not exactly correct.
Try not to think about it. It's beyond human comprehension.

So why don't we just search for wormholes and travel back in time?

look up special relativity

Actually the grass isn't green we just see it as green in the light spectrum.

well lets think about it
there is absolutely now hope in achieving interstellar travel anytime soon, as we haven't even sent humans to mars
wormholes are only theory, and if wormholes do exist they're proving hard to find
Of course time exists.
[QUOTE=Willie Nelson;22596769]So why don't we just search for wormholes and travel back in time?[/QUOTE]
One, trying to find a worm hole would take precious time and money. Two, considering we found one would take YEARS to reach. And three, scientists have theorized, once reaching the inside of a worm hole, it'll take some time before you reach a Singularity, in which time advances normally for you. But time would slow down outside of the worm hole and singularity. It would take a short time before communication with you is lost, and then, you'd be left to drift in the singularity/worm hole until you pass into whatever is on the other side.
once again recommending Singularity. It kinda puts this into laymans terms, and is good for teens/pre-teens.
[QUOTE=Mattofwiles;22596820]Of course time exists.[/QUOTE]
It does indeed. It's simply sad that most people are taught by teachers who thought otherwise. It's a basic mistake, especially since science has changed so much anyway.
Hell, I still remember my science teacher telling us all [B]'Light cannot bend, it's impossible'[/B]
[B][I]Heh.[/I][/B]

Well there could be a wormhole in your hot tub right now that only requires a russian energy drink to start :v:, just kidding but I see what your saying. Although one more question are wormholes only for space travel or time reversing?

Or in layman's terms, green.

you're thinking about black holes. wormholes wouldn't have singularities or any of that jazz; wormholes are simply rips in space-time linked to each other across space
[QUOTE=MrEndangered;22596847]Hell, I still remember my science teacher telling us all 'Light cannot bend, it's impossible'
Heh.[/QUOTE]
It's not like the scientific community's opinion on that changed anytime recently unless your teacher is like 200 years old.
They also only exist in theory, like most of science.

-lolsnip-
well fuck me sideways. billeh! was right. I'm thinking about [i]black[/i]holes not wormholes. Sorry!
Dude, what if, like, [I]your green[/I] and [I]my green[/I] were, like, different?!

well scientists look at wormholes for a prospect of interstellar travel, but a side effect of wormholes, because they are linked through space-time, is that you could wind up in a different time because you're in a different part of space.
hey physics experts
what's some good stuff to read if i want to learn about physics?
i don't really have any prior knowledge about physics but i'm curious

I guess so I will read up on those things, I was thinking about learning more before returning back to school so maybe I will be ahead.

Uh, general relativity, dude. Light bends all the time.
