I got a good question i heard somewhere. If an old lady gave you a watch when you were a kid and you went back in time now and found the same woman and gave her the watch back then did it every really exist? When did it come into existance? Does it age?

similar to the non-existant time traveling machine:

one day you find this battered up time traveling. it is broken, but you can fix it with modern technology. right as you get it finished, a war begins. to save the technology you send it back to the time in which you found it. during the trip it becomes damaged.

this entity has no 'start' or 'end' or creation date. same as watch, except you dont go back with it, which removes all arguments of human interaction, and having 2 of you in the same time frame.

aahhhh! how i love theory. did it age? well if there was a clock in the machine that kept continuous time (as in it was never reset), or if this watch kept continuous time, then you could prove it did age, but couldnt prove exactly how old it was (by the reading on the watch). then again, this brings up the possibility of an infinite amount of parallel universes in which every possible instance occurs (i.e. watch/machine traveling back in time once, twice, 3 times, 4, 5, etc.).

Time Travel is not possible, bcause time does not exist. It is an idea that is very diffucult to express in ordinary launguage, since launguage itself arises from our everyday experinces and includes time as a universal and all-prevading property of the universe. Thus the word 'begin' itself assumes a continual flow of time, one specific point of which is identified as the start of something. A beginning to time is therefore undefined, since the concept of a beginning already requires time to exist.

Its very much like 'Good' n 'Evil'. They dont exist in the laws of nature pre say. But are idea's invented by humans to better control thier/others lifes.
Its part of our launguage not nature...I believe theres no such things as, Good, evil, time... Its things we made. No one can be evil or good. We as a society over the genrations have decided ok were gonna call this 'action' BAD and if your caught doin it your a BAD person. But Is what that person doin really bad? you have to understand that god created the devil, hes workin threw people that do BAD to save us. The evil that they do is only suppose to bring something out in us. So is it BAD, that they are the way that they are. because its helpin us , its openin our eyes to something. It devopls us into the person we are today... Much like the rock in the river thatt is shaped by the water, We are the rock and 'good' 'bad shape us into form we are today.

sorry that human kind hasnt yet come up with an ultimate means of information conveyance, i.e. nam-shubs . but just because a concept cannot be described doesnt mean it cant exist. i understand what you are saying, but your whole argument was based around the fact that language cant describe the concept of time travel, which actually SUPPORTS the idea of time travel. humans know only what they can describe. we can 'dumb down' the idea of God, or what have you, but we could not completly comprehend Him. Because we cannot define it means there is more to it (time travel) than our brains (in their current state) can understand.

I don't belive in a conventional sense of time. I don't think humanity is thinking of time in any sort of complex terms. What is to say time is linear? Up until a few decades ago everyone was convinced space was linear as well, and now we think its curved. My point is not that time and space should be thought of in the exact same terms, but rather that it is diffcult for us to concieve of time as being non-linear, therefore we DON'T. It is impossible to concieve of time in its true form because it is infinate, much like space is infinate. The universe is constanly expanding... no one can really comprehend of that.

Infinity is not a concept the human mind is capable of dealing with because we think of everything in finite terms. Such as "I wake up at 9:30." It is impossible to ever really "be" at 9:30, because by the time your mind has conceived of "9:30" its allready a milisecond after 9:30. Also, there is not REAL 9:30, as time is a measurement, and all measurements are estimates. (dont belive that measurements are infinate? think about the riddle where the frog jumps half way to the well, then jumps half that distance, than half that distance... the frog never gets there, because you can keep dividing by 1/2.)

Interestinyly enough, one of the main things that separates human consious between that of intellegent animals (like gorillas or dolphins) is our conception of time. We are able to concieve of the future. Being able to concieve of the future is what really creates human consiouness. We can rationally say what we plan on doing next week, next month, next year, when we are 90, etc. We can concieve of millions of future possibilities, and plan for them, along with concieving generally WHEN they will happen.

Perhaps then the next step in the evolution of consiouness is being able to conceive of time in terms of infinity, or constant motion. Time is not a line, but rather an intangible 4 dimensional concept. Time does not run "backwards" or "forwards", as these words can only apply to something with has a begining and end, of which time has neither. We like to think of a "begining" to the universe (and in some cases an "end"), however, what if there is no begining? What if it has always been, and always will be? ...I can hear the sound of your head exploding.

But in all seriousness, what if time happens all at once, and we are exisiting in an infinate number of times at once. We like to think of time like being in a place- you can only exist in one PLACE at once, and you can only exist in one TIME at once. Like a movie, each "time" is a frame, and there are an infinate number of frames, so it is fluid. Counsiousness exists soley to put those frames together in some sort of coherent order.

What would happen if you split those time frames apart? (This is theoretically impossible if time is infinate, but imagine for a second that infinity can be interrupted, or rather, not interupted persay, but linked.) Something would be 2 places at the same time. This is in a way the idea of "time travel".

Ok, so some more on time travel. And here, my complete and utter mis-knowledge of physics may be revealed. But, my own lack of knowledge aside, there are a plethora of laws which link time and space. Mathematical formulas abound with Time Space ratios and relationships, down to the simplistic concept of Miles traved Per Hour. Some popular science fiction has toyed with these relationships, coming up with the theory of what would happen if one could travel faster than the speed of light?

Ok, this is actually a concept stepped in actual physics. So sorry if I lose anyone along the way. In all honesty I find this stuff pretty hard to understand- but heres how it works:

You're in a car chase and you're driving at 100mph down the freeway. Your shotgun-toting buddy (sitting shotgun, no doubt) Fires a bullet which is traveling at 50 mph (i dont know how face real bullets trave, but 50 is a nice round number, isnt it?). To you, the driver, and to your shotgun-toting acomplice, (who are both in the car moving at 100mph allready... obviously NOT a dodge aries...) the bullet is only flying by at 50 mph. To the parked police car which watched this all go down from the side of the road, the bullet is moving at 150 MPH. (your speed PLUS the bullets speed... duh). Thus the speed of the bullet is relative to the speed you are moving. Makes a certain amount of sense.

Ok, so here's where this nice little rule goes straight to hell: The Speed of Light (which happens to be 186,000 mps... miles per second).

So lets say you're now having a car chase down the freeway traveling at 100,000 mps (definately, definately NOT in the dodge aries... maybe the delorian... nevermind.) And your flashlight-toting acomplice decides to SHINE A FLASHLIGHT IN THE EYES OF YOUR ENEMY! (no, this makes no sense, I know.) To you the light is moving at... 186,000 mps... the speed light ususally moves at. Ok, and once again the parked/non-moving police car sees you from the side of the road. And what speed do THEY see the light moving at? If you said 286,000mps you'd be wrong, wrong, WRONG. The cops see your flashlight-of-doom� emmit light at 186,000 mps as well.

What the hell?

Ok, I (and genious-type physicists) cant even begin to explain this. Quite the paradox, eh? Its messes with that whole, rate = distance/time. (this means, essentially that if you are travel say, 100 miles in 1 hour the rate you are traveling is 100 mph.) So why the hell is this formula (perhaps the only formual i've ever understood in physics) so fundamentally WRONG?

The answer is... our perception of time is wrong wrong wrong. Hah. Think of it this way, for you, driving the car (delorian), for both you and the immoble cops to see light traveling at the same RATE, you must have been traveling at different TIMES. For your light to travel at the same RATE, you had to be moving at a slower TIME than the cops. Whoa, I can hear the sound of paradoxes forming world wide.

So what the hell does all that mean? Well, start traveling at high enough speeds (like, oh i dont know... 186,000 mps) And you're essentially going faster than reality. Oh, time passes at what feels like a normal rate to you, but time is really moving slower than time for someone who isn't moving. Think Rip Van Winkle... He goes to sleep, doesnt age and wakes up in the future... its like that with less sleeping and more moving at 186,000 mps)

Therefore.... If we can get going fast enough we can Time Travel into the FUTURE. Lets say I step into some sort of device that lets me travel at something totally ridiculous like 1,000,000 mps... Think of how much slower time is going for me. Then I step out and I'm... years in someone who WASNT moving at 1,000,000 mps's future. Coollll, huh?

What about travel to the past? Maybe. But this little theory only works for going FORWARD. Its not like you can reverse the whole thing and speed up BACKWARDS. (like if you were traveling NEGATIVE 1,000,000 mps you could go BACK in time... uh... but how does one travel at a negative speed?)

However, travel to the past is far from impossible. Lets say Time is curved, and goes in a crazy 4 dimensional sphere (except it wouldnt be a sphere since it has 4 dimensions and spheres are 3 dimensional... whatever... i have no idea what one would call that). whats to say one point on said sphere can't be linked to another. Like, draw a sphere, now connect one point to another... that conection is linking past to present or past to future. How do we make said link? How the hell should I know?

Anyways, I think the point to all this, (SOMEWHERE near the top of my ramblings)... is that TIME DOESNT EXIST.

[osiris]

heres something instersting to think bout, when you go outside and look up into the sky the stars you are seein are not how they look today, when you look at a star your looking at how it looked like millons of years ago, for all we kno that star might not exisist any more. You see a star is a burning ball of gas simlar to our sun and the light it sends out travels at 186,000mph and the closet star is a few millon light years away so that light traveling at 186,000mph would still take a couple millon years to reach us.... So by the time the light from the star reached planet earth, the star would already be a couple millon years oldder then the light were seein here on earth..... So we could still be seein the light from a star that dosent exist anymore... can u mimagine that?!!! its like some1 turned off a lightbulb but because of the "time" delay were still seein the light...

[Kjeldorian Royal Guard 42]

Time is man made. It has nothing to do with anything.

Thus it is impossible to travel within it, above it, below it, behind it, in front of it, before it, etc etc. It does not exist.

It's not real.

Attempting to solve questions like these with "time" is fruitless. It's a variable which does not exist. A red herring.

So if we live in a 4d universe (length, depth, height & time), and we have 2d shadows, how many dimensions would a shadow have in an 8d universe? Since 4/2 = 2 and 4-2 = 2 I cant really come to a conclusion myself with a sample size of one. 8/2 = 4 but 8-2 =6

[Mike]

my brain hurts

im shure this was already explained er something but im to stupid to understand it, but wasent there a theory that if you traveled faster than the speed of light the moleules in your body cant handle it or something?
