Anything exist outside the known universe?

The universe is about 13.7 billion years old because the farthest light visible. Existence (complete universe) is infinite. While the known universe is a bubble in existence.

My main point is the universe we know of 13.7 billion years old is not the final frontier. Do you believe there is existence which expands past the known universe?playmynutz

Thats an oxymoron
How can something be infinite but have a beginnning?
And on that point, how can you ask whether something is outside of an infinitely large object?

When you say known universe are you referring to the one we can see?
If thats the case, then yes, it's just that the universe is expanding faster than the speed of light, so we are losing more and more of the visible universe

However,
Time and space do not exist outside of the universe
So no, nothing exists

The unknown universe

1. The world is only 8000 years old, duh.
2. Probably not because God only created the Earth.

Sure. Why not?

no possible way of knowing for the foreseeable future, thanks to the Planck Wall.  Physics breaks down at that point and any speculation prior to the beginning of the visible universe is a waste until we get a better understanding of the physics prior to that or a better understand of why we have such a wall.

this actually seem impossible. i mean once we are able to observe it, it will be known, not unknown.

or some shit like that.

kinda like how tomorow doesnt really exist.

idk.

Probably.

 there has to be.

human comprehention can only reach so far in deep space.

The speed of light is only a limit on objects. It isn't a limit on the expansion of spacetime. According to the theory of inflation, the spacetime of the early universe expanded faster than the speed of light, and this expansion in a sense carried objects faster respective to each other than light. Technically the objects themselves didn't need to move at all (although they did)... they could be completely still in respect to their position in spacetime and yet those two objects would be gaining new distance with respect to each other. Therefore there could be parts of the universe which are not visible from our galaxy because they are carried faster than the speed of light respective to us by the expansion of spacetime, so that their light would never reach us.

However, even without the expansion of spacetime, I can see a scenario where this might be possible, although at least for now I have no idea if it ever happens. Since the limit is on the objects themselves, no one object can travel the speed of light. However, if two objects were moving away from each other at at least half the speed of light, with one of them exceeding half by an extremely small amount, then their combined speed respective to each other would be faster than the speed of light, and any light generated by those objects would never reach each other. That situation wouldn't necessarily be permanent though since one or both objects could for some reason be slowed down or change direction to effectively lower that total speed. As far as I know, it's not something that is known to occur right now anyway (at least not without the additional expansion of spacetime) as the fastest objects in the known universe seem to be rogue plannets going between 8000 and 9000 miles per second, and the amount of energy it takes for those two objects to actually travel that speed respective to spacetime would be immense and perhaps impossible to attain on just the objects themselves.

if it is outside the 'known' universe how the hell would we know about it in the first place?

It will always be spaceish. :P

No. he didnt mention god.

If we knew something existed outside of the known universe, it would also be known. Correct?

It's called Heaven. :cool:

I have a hard time grasping the concept of pure nothingness, so I'm going to say something's there, even if it's just a big black empty void, it's still a big black empty void.

Redshift is cumulative with distance, so that means the further away something is from the observer, the faster it's moving away from him due to expansion. So in theory there's only so far out that we'll ever be able to see, even given an infinite amount of time.

It's crazy how people figure this stuff out.

Still though, what I meant was that the thought of nothingness is just a bizarre one to me. I mean you say we can't see too far because light hasn't reached it yet, but absolute nothingness would mean there's no darkness in the area in the first place as nothing exists there. That's why I would have thought there to be something out there, even if we can't see it yet and wont be able to for billions of years. Then again that's just my concept of what total nothing would be.

I'm confusing myself, I can't even word my thoughts properly. :lol:

Xaos absolutely detested it.

The universe is a lie. There is nothing outside of our atmosphere. The lies spread about our solar system and universe were just put in place by God to test our faith. Plus the Earth is around 7000 years old like the rest of our universe. Duh.

how would we know what is outside the "known universe."  It would by definition be unknown

We aren't moving any closer to or further away from other stars (by any great margin)... Granted, we are supposed to be combining with Andromeda in the next billion years or so (I think) chaoscougar1

So we're getting closer to andromeda, but none of the stars of andromeda?

Do you believe there is existence which expands past the known universe?playmynutz
