If the object is frozen in time, wouldn't it simply disappear? I mean, if it was stuck in a single point in time, any time beyond that it simply wouldn't exist.

See, this makes more sence to me than it traveling forward in time.

Frozen in time is probably not the best word, but I mean frozen as in not moving not aging. Frozen, but not neccesary in time.

Ah. I see what you mean. It would be like if it was trapped in a box and everything changed around it, but it stayed perfectly the same. Although, I don't think we would be able to exert enough pressure on an object to create the effect.

It would be frozen in time if it was moving at absolute zero (I think, I can't remember the formula for it right now). However, if it was moving just above absolute zero, then it would be time traveling.

Its a theory that we can create absolute zero( molecules stopping ) , but we don't really know how we could do such a thing.

I heard some guy was really close to creating it, but used the wrong type of measurement, like grams or ounces and screwed it up. This was a few years ago.

It actually has been done, but only for a few nano sec. I brought up this exact theory of time travel to my science teacher two years ago, and he agreed that in theory it is possible.

Traveling into the future is very easy compared to traveling into the past. There are multiple theories in how to delay/stop time for x area for y amount of reactions in z area. Infact, some have already been proven. Such as that nuclear clock example.

But reversing the process or rearranging things exactly how they once were, is almost as impossible as impossible can get.

Doesn't the term "absolute zero" refer to temperature? Meh.

Ya, it does. It's 0 degrees in kelvin, -459 in Farenheit, or -273 in celsius

When something is compressed it gets colder though.

Until the pressure gets so great that fusion occurs, of course. ;p

Being very small is unlikely, as brains require a certain amount of complexity in order to achieve intelligence. If we find intelligent aliens that are small, then most likely they will work by some kind of group consciousness system (not based on psionics, of course, but on sound or light or something like that for communication, sort of like in A Fire Upon the Deep).

Maybe we are. How do we know what the seed universe is? It might be populated with a completely different species, or even have different laws of physics, depending on just what the time travelers are capable of altering.

Copernican Principle

The Copernican Principle is a logical convention which can basically be put as 'our place is not special'. That is to say, the assumption that we are in an objectively special place or situation is illogical and therefore tends to lead to false conclusions. It's something like Occam's Razor.

They have indeed come very close. By pointing lasers at individual atoms, they are able to hold them in place, achieving local temperatures within a few millionths of a degree of absolute zero. However, achieving actual absolute zero is impossible due to quantum mechanics.

No, it actually gets hotter. The reason it becomes a liquid and eventually a solid is because the molecules simply don't have the space to form a gas. The material itself stays very hot. Similarly, decompressing something cools it down. This is the principle behind a fridge: It compresses air, waits for the compressed air to cool down to room temperature, then decompresses it and ends up with cold air to pump into the area where you put your food.

well, my hypothesis about this does include that, it also compensates for the grandfather paradox and most other paradoxes for that matter. i dunno if its been posted sofar, but i'll post it up later after i do some work in paint .

But if it is so cold why do astronaughts not feel it. They say that in space there is nothing to moniter it like there is on earth. On earth the temperature finds a happy medium. In space yu could be in the view of the sun and it could be 200 degrees as the person right next to you could be in the shade from the sun and they could be in the -100 degree range.

What are you talking about of course they can feel cold. It's just for the record that if you do feel the cold you wouldnt live to say about it.

And shouldnt the discussion stay as time travel paradox not space itself?

Part of the reason we dont need to worry a whole ton about how cold space is is because we closer to earth. Out there near pluto in stuff its like -400 fareignheight. And it is still really cold in space.

omg download gimp now plz kthx

Actually, last I heard it was the Cosmic Microwave Background that had a temperature of about 3 kelvin, but the actual hydrogen particles floating around in space are very hot because they've spent eons absorbing energy. Not sure about this, though.

Because there's hardly anything to drain their heat. Space itself has no temperature, because there are no molecules in it. The only objects around to drain heat are a few specks of hydrogen and whatever equipment the astronaut is touching. So basically the same reason why jumping into a 5 degree swimming pool cools you down far faster than walking out in -20 degree air; the water may be warmer, but it has a far larger capacity to drain your heat. In fact, spaceships often have a problem with overheating, because they have nothing around to absorb the heat; I believe some have already been equipped with radiators to let off the energy as infrared radiation.

Well, proximity to the Sun does a hell of a lot more for a spaceship's temperature than proximity to the Earth. The Earth doesn't radiate all that much, the Sun does.

ps spacesuits also have heating

Well, I think more properly they have temperature regulation. Heating is sometimes necessary, especially if you're in the shade. At other times it can be more useful to cool down. Of course, small objects such as astronauts have less trouble with staying cool than large objects such as spaceships.

If it is frozen... its not going anywhere..... ever.



No, it would be there, but it would never change.


Anyway

Space dose have stuff in it, its just so far apart that they mey as well not even be there.

Also, noting in space holds heat.......

What are these things in space? Stars, Planets, Rocks, and Man made objects are in space. I cant think of anything else. Unless you are talking about small microscopic molecules and atoms.

It's small atoms and the like.
