If we somehow manage to get out of space what would be outside of it how would it be.

This image represents our universe or space what do you think is outside. |

You know the current theory is just that it all starts over again when you reach the "edge". There's no edge of the universe anymore than there's an edge of planet Earth. It's like a globe, except if you could imagine a 4 dimensional globe, where the 3 dimensions we're familiar with are the globe's outer surface. If you travel in a straight line in any direction for long enough, you will end up right back where you started.
Now..... I'm not saying I believe this, but it's what Big Bang cosmology predicts. |

The curvature of the universe is almost incredibly flat, so you would not be able to go in one direction and then return to where you were. WMAP has shown this:

The universe is everything, so you cannot go somewhere “outside”. |

Well if we are too spacy, then we explode, so I suppose outside space is where the suicide bombers go... Does that make sence?

Einstein say x1 = +x, x2 = +y, x3 = +z, x4 = ict
I say 2 dimensions can't have the same sign.
And that time has one direction is positive
x,y & z has imaginary sign compared to eachother else they wouldn't been arbitrary +/- directional.
ctt + ivtx + √(-i)vty + √-(√(-i))vtz = distance |

As you can see from the picture, what is outside, it's WMAP 
Seriously, if we can think about the Universe as a whole, it's inside our mind. So, we are outside |

I agree with inow. However, if we could discuss things philosophically instead of purely scientifically we could probe what may lie outside the universe. Even some science theories tell us that there are many universes (but I don't agree) so that may be something you are interested in. In philosophy there are valid cosmological arguments and ontological arguments that use logic reason and science to make a case for things unknown to science including an intelligence (or accidental) origin to the universe. At least one was created by a scientist on par with Einstein who developed an ontological argument for the existence of God. So I have always claimed its rational and even logical to believe in the existence of God and things that exist outside of time and the universe.

| By your same reasoning then, one could claim it's rational and even logical to believe in the existence of the Easter Bunny. |

There could be no space out there.
If there was no space, matter couldn't exist outside, and therefore we have zero chance of seeing it.

But what if you move ana or kata (the fourth dimension)? Then where would you be?
If there was any space out there, it would be incredibly useful, as we'd be able to hold an infinite amount of matter there (even if it was only one centimetre: an infinite amount of cubes fit into a tesseract). |

You aren't making any sense.

If there was space out there, it would belong to the universe by definition. It's a paradox. |

If you take space as literally nothing defined only by what occupies it (it does not curve. That is the effect of gravity travelling through space), then you could in theory travel to the edge of the physical universe and beyond that would only be photons (as they travel faster than matter), and beyond those, literally nothing.

Well you could claim that but your claim would be neither rational or reasonable. It would not use logic or science like all of the cosmological and ontological arguments do. Additionally the cosmological argument I am fond of (the KCA) is a logical syllogism. So if you could come up with an Easter bunny cosmological argument (for the existence of God etc) that formed a logical syllogism and was a valid cosmological argument you may get famous. If you cant you would only be regarded as a buffoon (If you insisted the Easter bunny was real).
After I wrote the above response it occurred to me that you may not know what a valid cosmological argument consists of. It consists of premises, usually at least three, these premises should be axioms. Ideally these axioms should form a logical syllogism, in the case of the KCA those conditions are met. In claiming the Easter bunny exists none of the conditions are met so your statement/reply is unreservedly false.

Someone mentioned the fourth dimension, that would be time. In classical phyics time is the fourth dimension! Also you all' may be interested in knowing that space is filled with fields, energies, and virtual particles etc. Unless you want to entertain philosophical metaphysical concepts, there is no such thing as empty space, at least as far as pure science is concerned.

Oh to answer the question as to what is outside space, I think that is Gods realm, and the spirit realm. It would have to be atemporal and boundless so if we could exist there it would be in mind only. This isn't to be confused with a cosmological argument, its simply a guess and maybe my belief.
