Thoughts on time travel

[Dolentrean]

Take a physics class! is like nik0tine said, time travle is imposable, but we can ajust the rate that time flows. The space time continum states that time exists within space, not space within time. Time is affected by your speed, as is your mass, techniquly people who fly jets age better than the rest of us, because they are traviling at a slower "time" as they are travaling at very high rates, even though the diffrence is almost non existant. This CAN be proven, they have taken two atomic clocks set to the same billionth of a seconed. They took one clock into a jet and flew with no particular speed for an extended period of time at a very high velocity, when they landed the clock that was in the jet was "slightly" behind the normal clock!

It's easy! To travel back in time, you need a wire coat hanger, a banana, yesterdays newpaper (the times) and a G-force generator.And then, using my kick-ass black hole genrator (tm) you can genrate a black hole,build yourself a pod, and go back in time. The newspaper determines how long ago you want to travel back in time. So if you want to go back to yesterday, get yesterdays newspaper. Ps, the ndewspape MUST be the [I]times[I] If you want to go somewhere before th times was created, hard luck.

PPS: I've never tried it. And the Kick-ass black hole genrator is still in production. All you need to do is to go forward in time to get it when its done.

PPS: I don't know how to go forward in time.

This thread remind me of the Chrono Trigger and Chrono Cross.

Time travel simply isnt possible...

[Madame Adequate]

The best evidence suggests we can't travel back in time. I say 'best evidence' because science is retardedly fond of saying 'This is incontravertable fact' without knowing that it is.

I think the best evidence is in fact that there's nobody from the future messing things around. Although that argument does completely fail to take into account possible restrictions, both legal and quantum. But yeah, if there were time machines, you can bet I'd have come back top help myself out.

Well I don't know if anyone has said it yet, because I can't be bothered to read every single post, but if you go to space and stay there a while when you go back to Earth everyone you knew would have died of old age...

I haven't taken physics classes and I just know all this stuff of my own research.

Infinite mass requires infinite energy to move am I right?

[Old Manus]

I don't know much on time travel, but I do know that it would be cool

Napoleon Dynamite had a time machine. It didn't work. And he even put the crystals in. Gosh.

[mooglebunni608]

if bill and ted can travel back to So-Crate's time in an old phone boothe, then time traev IS possible

[Shoeberto]

By 2056, time travel will be realized, and in the past it will be difficult to tell if your best friend is not a rogue time traveler.

If Time-Travelling into the Past is something that is going to be invented we can assume the following Either Or's:

- Events have already gone as they are but we just haven't yet detected them for one reason or another. Who's to say some people from the future don't already live among us and have influenced our history and we just don't know about it?
- Events have happened, but have created the "alternate timeline" scenario. It works something like this. Suppose you live in Timeline A, our timeline now. The moment you go back in time, you've effectively changed events, creating Timeline B. So when you return to the present it's not your original universe at all, but rather an alternate one. It would give explanation to the idea of the "Grandfather Paradox", in that even if you were to go back and kill your own Grandfather it would have occured in Timeline B. Since you are a product/resident of Timeline A the change wouldn't affect you. This raises the issue of if you changed events so that you didn't go back in time but were still alive. Upon returning you would've effectively cloned yourself.
- Time travelling to the past doesn't affect timespace at all, and your presence is essentially voided

[Del Murder]

What has happened has already happened. So if you go back in time, the things you do would have already been realized in the present.

That being said, there is a possiblity of alternate dimensions exactly like our own. And when you 'time travel', you are really travelling into an earlier time in another dimension. In which case you could affect things, since your history happened in your home dimension and is not dependent on what you do or did in the other one. That way you <i>could</i> kill your grandfather, but it wouldn't be 'your' grandfather, just a double of him. Killing him would mean your self of that dimension would never exist. I probably didn't explain that very well.
