thefinalword: just to answer your question (even if it was somewhat rhetorical)

...No to travel at or beyond the speed of light you would have to have no mass i.e turning ure body into pure energy which is never to good for you =P

The only real possible way to travel back in time rely on the occuranase on thoertical
abnormalities predicted by are current (incomplete) physics theorys (wormholes and the likes) these however would require insane ammounts of energy to create let alone control without harnessing singularities and the like which could be somewhat hazardous to health.

Time travel is dangerous if you don't have silver.

I don't know what's more sad, the fact that I understood all that...

or the fact I can't time travel to cheat on my test today...argh.

^ notice that 11tc said "The only real possible way to travel back in time"

And what's up 11tc? enjoyed my topic?
please post some more

i don't think time travel should be used...i mean, why can't anyone just let go of the past?..for me, if you change something in the past..you'll never know what will happen in the future...like for example the Back To The Future movie...it made a lot of sense

of course, we might find it amazing and get curious and all....but it's never good to mess with what happened and what will happen...

past is past...let's all move on and look forward to our future..never look back...

well, at least that's what i think....hehe...

whats up mauz =P id post more but im rather opinionated so i find myself on thin ice in most threads that involve religion or politics etc (very tempting to do some christian zealot bashing in the gay marriage thread).

Back on time travel it might be nice to quote hawkings again when he says "You might think this whole section is part of a goverment cover-up on time travel. . . . you might be wright."

As for traveling into the future rather than back in time as you pointed out. Its generally accepted by the physics community that you can travel into the furture of 1 area or object if ure relative speed is significantly faster (since the closer you get to the speed of light the slower the time you experience will be relative to a slower object hence the twins paradox decribed above where 1 twin returning from a high speed space journey finds himself to be 20 years younger that the other)

do you know why some say that even if it's possible to find a loophole to cheat the speed of light, in theory you would only be able to go back until the time the "time machine" was created? that would explain why we don't have any time travelers popping up in this time.

this is because they are talking about creating wormholes that loop back on themselves so when u step in you come out at the point where the loop was created. This is really simplified im afraid but a general explanation would be that if u stepped in 100 years later ud be able to come out around the creation point but naturaly you coundnt go back any further since the loop would not exsist without creating some horrible paradoxes.

I think of it like this. Anything with moving particles is traveling through time. The faster you move the faster time flows for you. Similarly the slower you move the slower time flows. When a person is cryogenically frozen and reach a temperature at or near absolute 0, time stops for them. This is so since they are completely still, not a single cell is moving.

I don't think traveling to the past is possible, especially not in any practical way.



You kind of have it backwards. Increase in speed is inversely proportional to time

Oh yea, that's what i meant. Said it wrong.

its possible right? all the physics etc- just dont think it would be a great idea though! i can see so many ways that we could mess everything up!

I think all the big problem is the inability to manipulate the fabric of time itself. There are millions of theories on how to do it, why it is possible, etc. But there are no machines that rip through space time. There's no computer program that can do any of these things. ya know? I mean it really depends on what you believe in. Supposedly in the 'Montauk Project' they were able to go back in time, also they were able to go into the future. They created a paradox that linked back to the 40's, the 'Philidelphia Experiment'. Where the submarine 'Philadelphia' was pulled through a time vortex and held inbetween times. (Not a part of the present, not a part of the past) This state lasted for x amount of time (minutes if I remember correctly), then the submarine appeared almost 400 miles away with half it's crew fused to the boat, another 40% who were conscious, not fused but were walking around batshit insane and then a small group that was sleeping the whole time was fine, no problems. Didn't wake up during the experience so they don't remember it ever happening.

Ok, now that my tangent has ended I suppose I'm trying to say that I'm a skeptic that does believe it's possible. It's just we don't possess the technology to actually execute the theories our minds can create.

M Theory is interesting too. but my brain hurts so maybe I'll add more later...when my mind is expanded. lol

Time travel is occurring right now, so logically there has to be a way to warp it to our will.

I made some rules for future time jockeys:

1 Traveling to the past to change something will erase the purpose for the original trip. Thereby allowing it to occur, forcing the trip, erasing the problem, allowing it to occur, forcing....you get the point.
You might trap us all in a "timeloop". If this does occur we will have to hope for the Harry Potter timeloop where they just miss each other barely. I wouldn't risk it, therefore the Past is off limits! (unless to a point where the machine has been made)

2 You can go to the future. AND STAY THERE!

3 Don't timetravel too much. My theory is that going faster than light creates a temporal shockwave(deja vu theory), much light a sonic boom. At worst, don't timetravel too far, or the shockwave might tear apart existence.

That reminds me of the movie The time machine. He built it to save the girl but then he couldn't save her because then he would never have built it in the first place... all around it was a bad movie 3 out of 10 on my movie scale.

On page 7 I think Haddon talks about the terminator time loop... Another thing about that is in terminator 2 when they try to destroy Cyberdyne so that judgment day never happens wouldnt that have screwed everything up because then Reese never would have been put back in time? And then they go and make terminator 3 but Judgment day was made to be later then 97 wouldnt that also affect the time line? Not to mention terminator 4... if its made is gonna have something to screw with it all to
