time travel -- at least foward--- according to einstein, is very much possible.

[flexbuiltking]

Ok.. your first point makes sense


BUT I still dont understand how travelling faster than light would make you go into the future?

Imagine this .

.WE sit on a ray of a some BEAM that moves way faster than light , ignore the huge accelaration that could kill us! Lets assume within one minute we are travelling faster than the speed of light.

On the other hand light travelling from say me banging your mom 5 hours ago is travelling at ofcourse the normal speed of light, after a hours or days you gonna certainly catchup with the ray of light that portrays your mom screaming in pleasure. You will then see what happened 5 hours before we actually took off on the beam..but again thats just like a porn video tape, I cant actively have sex with her


So basically travelling faster than light will show you what happened in the past (in this case, your mom getting it from me) but it doesnt mean you are actually in the past and definately not in the future
Get my point now?



PS- If you really wanna contradict this , you will have to explain the Twin Paradox theory to me, never could understand it..especially When I had my dick in your moms mouth.



J.k Bro , no need to get mad at those mom jokes

Time travel is theoretically posible via worm holes. If we ever get the capability to create a worm hole, we would be able to travel back through it. Dont start a topic on something you know nothing about.

[flexbuiltking]

ah and you are......... Einstein?

On a more realistic note are you even Stephen Hawkings?

1 ) We begin with a basic concept -- one that sets the scene...

You're on a train that's moving forward at 50 mph. You throw a ball in the direction that the train is moving. Relative to you and the train, the ball leaves your hand travelling at 20 mph.

Question: From the point of view of someone standing alongside the tracks, how fast is the ball moving?

70 mph

All you have to do is add the speed of the train (50 mph) and the speed of the ball (20 mph).


50 mph
+20 mph
----------------
70 mph


2)OK. Everything so far makes sense. Let's move on to the speed of light for a moment.

In 1887 two American scientists performed a now-famous experiment. The experiment seemed to show that the speed of light was independent of motion. In other words, that light always travelled at the same speed: 186,000 miles per second. It didn't matter if the source of the light was moving or if the observer was moving.

There was another indication that the speed of light was constant, too -- one that Einstein found especially difficult to ignore. James Clerk Maxwell, the mind behind electromagnetic theory, had developed equations that described the nature of electricity, magnetism, and even light. These equations, the predictions of which were confirmed by experiment, by the way, implied that light always travelled at the same speed.

Which brings us to the next question...

3 ) Again, you're on a train. This time, though, the train is moving much faster -- at half the speed of light, or 93,000 mps (miles per second). And instead of throwing a ball, you turn on a flashlight.

Question: How fast is the light travelling relative to the observer standing alongside the tracks?

186,000 mps

Relative to the observer, the light is moving at 186,000 mps. Seems non-commonsensical, doesn't it? But this has proven to be true through many experiments over the years


Here's our last question. This one's like the previous one, but with a twist. Again, you're on a train moving at 93,000 mps, and again, you turn on your flashlight.

Question: How fast does the light travel relative to YOU?
186,000 mps

Relative to the man on the train, the light is moving ahead at 186,000 mps, just as it is for the observer outside the train. The speed of light remains constant for all observers.




In our second and third train examples, the speed of light turns out to be exactly the same for both you and the observer standing along the tracks because time, as measured by your watch, ticked along at a slower pace than time measured by the observer. Not only that, distance changed, too. For the observer, a one-foot ruler whizzing by on the train would have measured less than a foot.

The weird thing is that, for you on the train, time wouldn't seem to be moving slower and your ruler wouldn't be shorter -- all would appear normal. However, time on the rest of the Earth would appear to be ticking along slower and its rulers would be shorter.

Now let's say you want to do some time travelling. You board a spaceship and take off for deep space.

The ship approaches the speed of light. Time for you seems to pass as it always has. It takes you about five seconds to tie your shoe. But to an observer on Earth (assuming he or she could watch you), you are moving at a snail's pace. It takes hours to tie your shoe.

Anyway, you continue on your journey. You slow down, stop, and accelerate back to Earth. You arrive home. You have aged two years during your flight. Two hundred years have passed on Earth. You have successfully travelled forward through time.

Now you want to go back? Sorry. According to relativity, you can only move through time in one direction.

C'mon, no Dr. Who fans here?

Time is infinite, mayhaps it has will have been invented in the future and they will have been going back in time, but since the total time into which they will have been gone back to is infinite, the probability of them having been ended up in any time we have yet encountered is 0, which is why we haven't seen them yet.

According to Douglas Adams, after it was invented, time travel was quickly abandoned since nobody could come up with coherent verb tenses to describe all the possible situations.

[wscranston]

aserecuba,

How do you know all this sh*t? You seem to have an encyclopedic knowledge of many disparate subjects, like history, religion, and, now, Einsteinian relativity. Just wondering.

And you seem to be in many widely separated locations from day-to-day: Columbia, Hawaii, Las Vegas. What's up with that?

Is it possible that you, sir, are a TIME TRAVELER?

[flexbuiltking]

So you are on this train, say for example the train is travelling at the speed of light, no more no less and you decide to turn on your torch and point it's light in the direction the train is moving.

Is your torch going to come on

Yes.

Asercuba, your example is accurate, but a little non-applicable.

Relativistic theory hinges on the fact that the speed of light (which is technically the speed of an electromagnetic wave, they all go "light speed") cannot be reached by matter, nor can it be broken. However, once speeds start to approach ~10% of c, some neat things start to happen.

Talking about the changes in volume and such have no application here, so we'll think about time. Time dilation occurs at ANY speed, it's just so minute in terms of reference frames that it makes no difference. It's been proven that if two atomic clocks are perfectly calibrated and one is taken into a supersonic orbit speed, when it comes back after a given interval it will be slightly behind the one that stayed on the ground.

Extrapolate this information a bit. This would mean that the closer and closer something got to c, the slower and slower time would go. At the point of exactly c, time would stop for the object in motion. Henceforth, going FASTER than c would result in time starting to go backwards.

Now, go back a little, didn't we just say relativistic theory is based on c being the maximal speed? Yes we did, which is why relativity starts to fall apart at speeds of c.

Enter black hole theory. Read around about John Titor (whether or not you believe in his time travel is irrelevant), his discussion on the logistics of time travel do make sense. The idea is that the closer one gets to a black hole, time is warped to the point that if one were moving quickly enough, time would indeed start to move backwards.

There's currently a guy out there whose name I can remember that is working proving Einstein wrong, in effect. Thus far, he hasn't found a flaw with his theory. And CERN has let it out that they're in the process of making mini black holes. By 2007 they should be able to do it.

As for the logical argument, why would time travellers be allowed to come back and screw with the past? You would think anyone time travelling would be under strict orders (and probably supervision) to be as low-key as possible. It won't be a joyride at any rate.

[aserecuba]

so theoreticallly, as you aproach the speed of light you would travel foward in time. as you surpass the speed of light you would travel backwards.

ps. john titor seems to be the real deal.

This is the logic I use. Well said.

[Hurc]

If you take chaos theory into account - the butteryfly effect - it becomes impossible for a time traveler to reveal himself or change his history. Any little change would have the potential to interrupt the development of the time machine in his timeline. From the second he arrives the probability of him entering the identical time machine at the exact same time in the future begins to drop until *poof* his entry into the time machine is effected and then could never came into the past in the first place.

If travelling in the 4th dimension were a possibility and was done, the very fabric of what we know as reality would completely unravel.

True to an extent, although you make the assumption that a) the past doesn't take into account anything he goes back and does (think 12 Monkeys), and b) that there is a single timeline. Way too much pseudoscience there. Simply put, it's impossible for you to go back and, say, kill your dad because that would be translated to the future and you would not have existed to go back and kill him etc... Because it would have already happened. Changing the past is an impossibility by nature, since it already happened. Any attempts to fix things would invariably either do nothing or turn into the catalyst that causes them.

Again I refer you to the story of John Titor. It's a fantastic look into the nature of time travel.

yes but until we develop it we can not know about it. because if time travel is invented in the year 2150, it will only allow for backwards travel up to 2150.

NO!!!! You CANNOT surpass the speed of light. This is proved by the famous e=mc2 (that's squared - cannot make superscript).

That is E=Energy, M=Mass, C= the speed of light.

The essence of the equation is that you can't even reach the speed of light. As you approach the speed of light, mass increases, therefore it would take an infinite amount of energy to move and infinite amount of mass. Meaning, you would never reach the speed of light.

The only way around this is through a different wormhole theory than the one described above. The problem with black holes, is that one cannot enter a black hole and survive. According to Stephen Hawking, as you approach the black hole, the difference in gravity between your head and your feet would be so great that you would be stretch into a very long strand, like spaghetti. This is forgoing the Even Horizon, which is that point of a black hole from which nothing escapes, including light, and time. Therefore, once you pass the Even Horizon, you aren't coming out.

Wormholes are not black holes. In the wormhole theory, image space/time as a fabric, for example imagine a sheet of paper, roll it so that you are holding the top and bottom edges in your hand, forming a "U" shape. Now take a pencil and poke it through the top and bottom of the sheet. That's your wormhole. If you move the location of the wormhole exit, as you are passing through the wormhole, you would exit earlier in the space/time fabric than when you left. That's the only way to travel back in time, according to the current theories.

Time travel has already been proven legitimate.

Super accurate timing devices have been accelerated to very high speeds and after the experiment, the devices had run slower than devices that were not accelerated. Of course, the difference was only fractions of fractions of a second. We just don't have the technology yet to approach close enough to c.

Faulty logic. Creating time travel doesn't create a point in time that becomes a barrier. The technology of it won't suddenly make a "system restore" point (to use some PC terminology) that is the earliest we can go back to. The ability to travel through time itself has no bearing on how far back can be gone.

Or do you mean that the origin point is the furthest back? If that's the case, then there is no backwards travel, only a return path from the future. But think about that for a moment. But taking the time dilation into account renders that irrelevant.

Yes, they also performed experiments using atomic clocks and an airplane. The clock aboard the plane was a few billionths of a second slower than the clock on the ground.

Not yet. many people said that controlled flight faster than the speed of sound would never happen. and look what now.

No wonder airline pilots look so young and healthy. All that flight time makes them look a thousandth of a second younger than they really are.

Unless we develop a new system of physics, e=mc2 prevents us from reaching the speed of light. It's physically impossible. Because of time dilation and mass increase.
