ahh yes but you see its been proven that the galaxies are moving in toward the center of the universe what happens when all of them reach the center no one know but it is a proven fact that they are moving toward the center

Actually, there is no centre to the universe, and there is no edge to the universe. The universe is infinite, which is, put simply, impossible to imagine. If there were a centre to the universe, we would be able to find it due to differential expansion. However, Everything in the universe is heading away from everything else in the universe, at the same accelerating rate.

As to time travel, it depends on which way. Travelling into the future is relatively easy, as that is what we do all the time. Getting there faster is just a case of moving faster. The closer you get to the speed of light, time (from your perspective) slows down. According to relativity, if you ever were to attain the speed of light, time(again from your perspective) would stop. Then if you could go faster than the speed of light, time would begin to go backwards. However, all of this is moot, because you can't attain the speed of light, much less go faster. It's just not possible, unless you have no mass.*breathes again*

Even if you could travel back in time, it would be extremely dangerous. Anything you did would change the future, including the act of simply existing in a timeframe where you don't belong. There are various paradoxes to explain this, but I'm very lazy, so if you want to know them, just google it. ;)

And I apologise in advance for any broken synapses I may have caused, but that's what happens when you take an astronomy class. :lol:

I heard that they figured out that the universe is a sort of soccer-ball polygonal shape, and if you go out one side, you come back on the opposite side.


You know what's so weird about that? Thgat theory is something I figured out for myself, together with a lot of other ideas. I've believed these personal theories for years, and just recently found out that these theories accually existed already. :yfok:

A friend of mine is addicted to black holes, and he made a program today with which you can see how big you would be if you'd be a black hole.

The earth would be

I'd be

I was thinking if there would be a limit to a hubble volume...
It doesn't makes sense if it's unlimited, and yet would be very logical and... okay... I'm confused :yfok: ... maybe you would get those weird black hole conditions at the borders :P .

You guy's don't think Time travel (called TT from now on, as I am too lazy to type it out.) is possible? Why not?


Einstien said that the universe was round. Abomonation added that it was rotating.

Say it's rotating this way: ---->

What if we get a super fast ship or something that was travelling at the speed of light to go to the very edge of the universe and spin that way really, really fast - faster than the universe. Then, we go back to where we where (earth). Having travelled faster than the universe (and having TT faster in return), wouldn't we appear at time later than the universe? ... Uhm, that came out wrong, but I can't think of what to say. Raise your hand if you understand.

"raises hand"

i get what your saying the only problem with that is that you would have to travel faster than the speed of light in order to arrive forward in time now you see since nothing can travel faster than light it would be an impossible feat to accomplish

Hmmm. You have a point.

Okay, TT backwards (as in, backwards in time):
You go out of the universe. Say time travels within this universe, like so (Pretend this is a circle).

_______
|TIME....|
|T.......T.|
|I.......I .|
|M.......M|
|E........E|
|TIME....|
---------

So, Say you hop into your space ship and you get outta the universe this time... back go <---- that way?

Would you not go backwards in time?

The chance that timetravel is acctually possible is somewhere between 0.0000000001 and 0.000000000001. Einsteins theories allow it but the "newer" ones don't.
Even if it is possible it would paradox everything to oblivion within an instant.

Tell me about it. If you were to accidentaly do something that made it so you were never born, you would cease to exist, at which point you couldn't have gone back in time to change it, which would mean you would exist, but then you'd go back in time and kill yourself, but then you wouldn't exist, which would make it so you couldnt go back and kill yourself, but then you would exist, killing yourself in the process and...ouch...infinite loops suck.

well say that timne wasnt escapable like point a will reach point b

A1 your friend is killed in a war saving a town


now say there is a new altrent time line,

A2 your freind dosnt go to war and dosnt save the town, and it is taken over by enime forces, with invade your country , whickh leads to the death of your freind.

If this is true time awalys gose form p[oint a to point b and there is no way to change the out come, just how it gets there.

Since time has been determined to be seperate dimensions at which we all move forward at a set rate, if matter on the dimension of time could be miniplated or even exist.

Yeah, you're better off just leaving time alone(and so is everyone else. Not to mention the universe), doing what you can with the time you've been given.

Yes, Universe could be rotating. I raise my hand, even though moving in a circular motion at speed of light could end up in results i can't even think of.

I don't think the universe is actually flat. I think that's just how its represented in diagrams of wormholes and black holes. Otherwise, you wouldn't be able to diagram them, because you'd have to draw in 4 dimensions, which isn't possible. :blink:

Actually, those drawings are in 3 dimensions, because they switched the length into the 4th dimension: time. So the drawings show 3 dimensions, but not the ones we are used to. Lets say

----» time
^
|
| height
|

-- width


Drawing in 4 dimensions is not possible, because the fourth is time. Anyways, time on a picture is not really usefull, right ?

The universe is not flat, what is flat on the diagrams is the flow of time, and the holes and tubes represent deformations, like a bend.

Remember, the universe is not restricted to 3 dimensions. We just see 3, but that is not a proof.

Let's say the whole world was flat. Humans would be squares and circles on a huge board. Now, let's say someone (in 3d) puts his finger on the board, and then removes it (third dimension). The squares and circles would "see" a shape in the form of a fingerprint appear from nowhere, then dissapear.

Now if we apply this to 3 dimensions, humans (like us) roam a 3 dimension planet. Now let's say a person travels through time (the fourth dimension) then comes back, we would see someone appear to us in 3d, then dissapear, exactly like what happened to the 2d world in the first example

What we need to learn from this is that we cannot percieve the fourth dimension, just see it's results. Time travel is just another result from the fourth dimension, even though it's probably as simple to a man in 4d as removing a finger to us.

Thank you for reading

There is no simple way to express these things. If it's simple, it's not true.
