There is probably no outside system(as yet lol), rather different iterations of the same universe(kind of). The "border" might be closer than we think

Hehe.

The Universe has no borders.

Lol

Everyone must have seen that image by now but as the old saying goes "a picture is worth a thousand words"...

If god exists and the universe was created for humans he made way too much black stuff...

And some would argue that if there is no God then a lot of real-estate is going to waste.

That is one of the lines in the motion picture -Contact-.

I know there is nothing outside the universe because the universe is all that exist. But then since the universe is finite, what would it's borders look like? I mean there's a point where the universe stop, and what would be the conditions there, and what would it feel like if I would touch the ''wall'' of the universe?

The universe is infinite. There is no "outside".

I think we shouldn't assume this because only a few hundred years ago, most people saw the earth as flat. Just because they didn't have the whole picture. Not because they were less intelligent.

We certainly don't have the whole picture yet. The universe is not infinate, rather infinate in theory.

In the theory of relitivity, the speed of light is represented as infinate for reasons of ease/elegance. Because it is an absolute of speed (kind of). But the speed of light has a finite speed. The same goes for the universe. Quantum theory can't exist outside so the universe is represented as infinate.

There must be more...

How is it possible that you can spell finite but not infinite)

What a pointless post...

How is it possible that you can't punctuate correctly?

The typo i made was made on my droid. Saving a typo is as easy as pressing space. Then your stuck with it until you notice yourself or some bored smartass (who can't punctuate) points it out.

Universe.....endless imo also

Visible Universe....view back into space time. the result of "our big bang" and a very beautiful place

Big Bang......super massiveblack hole gone super nova?

Dark Matter....remnants from big bang (smoke?) or possibly the matter of the universe outside of the visible "our universe"?

one of my interests.."astro physics.. theory"

The void outside the influence of light and gravity is infinite, the matter/energy in the universe is not.

Infinite matter/energy violates the second law of thermodynamics, and the arrows of time.

The universe is not a perpetual motion machine.

All science thus far is merely perception. What we can perceive from a tiny planet on the edge of a galaxy floating somewhere in the universe.

We don't know if the universe has an edge since by the time we can actually observe it, it's billions of years old and thus what once was, might not be.

Still, to f**k with your heads a bit...what if black holes lead outside the universe, thereby creating their opposite, the white hole. A white hole would essentially be an inversion of all physics we know. Or perceive.

Riddle me this then. What would the edge of the universe be comprised of? Radiation? Dark matter?

Or maybe this Universe is god's left testicle.

All borders are comprised of something.

The edge, or border of a square is comprised of a line. I've heard that the edge of the universe is just a massive field of radiation...but if so, what is keeping it there and keeping it constant?

Motion is an illusion. So is time, and thus so too the concept of "perpetual" and "infinite".

The true nature of reality is allowed to violate our feeble "scientific laws", because we made them up to explain our perception, which is also an illusion.

And what's this of a "void"? Isn't every "void" in the universe really comprised of dark matter/energy (which we don't know what it is) and mirror particles? Strings looping back on themselves and whatnot.....

the problem is the geometry of the universe could be such that it folds unto itself, meaning it would have no "real" border but a finite size nonetheless

No, that field of radiation is not the edge of the universe. It is called the cosmological horizon and only represents a limit to far we can see with a telescope. The radiation is what existed just after the Big Bang.

My apologies, I wasn't aware that the point of discussing the fantastic possibilities of reality was to get you out of traffic tickets, I'll be sure to plan any future speculation accordingly.
