if there are an infintie number of alternate universes could that mean that there is a non universe somewhere?

Question

this gave me a headache!

i got thinking about different dimensions and the theory of alternate universes and it got me thinking we think there are an infinite number of dimensions and an infinite number of possible universes whithin those dimensions and if that is right does that mean that there are non-universes, absolute nothingness?

Answer 1

Would not all alternative universes be non universes to the one you are observing from?

Answer 2

Don't know but when your brain explodes after thinking and puzzling it over......get back to us and let us know! Anyway, I'm now off to alternate universe xx711b to celebrate Xmas.....it's a few days earlier there due to some hyper spacial anomoly containing molecular debris from the collapse of someones brain that was thinking about alternate non universes.........or something! Watch Stargate........perhaps Sam Carter (Ohhh YES!) will answer you question...........

OR.....Theorise this....

A scientist once theorised that our Universe is contained within a molecule ! That molecule was contained within the body of a larger being. Now multiply all the molecules in that body. That being was contained within the molecule another being.......continue this possibility and take into account all the molecules contained in all bodies of all the possible life forms of all the beings within our universe! Are we talking 'infinite' and 'alternate' universes.

I only thought I'd mention it.............if anyone can work out how many universes that would make..........don't let me know!

Answer 3

If your variable of thinking is Universe. Then existence of non-universe will not be logical. However, if you think of something in which universes are contained, then that could be another dimension. You might be thinking of the margins/limits which may be the meeting points of different universes, which might lead you to the dimension of container.

Answer 4

If there are infinite different universes then yes there must be ones with nothing in them.

I am told that currently the favourite multidimensional models of particle physicists contain 11 dimensions for our universe.

I am not aware of any models which contain multiple universes (the universe is defined as everything).

try not to think about it too much, it hurts my brain when I try.

Answer 5

Here is one for you.
if alternate universes exist ( theoretical )
they can also exist on different dimensional plains.
we may exist in a higher dimensional plain.
we can see only see 3 dimensional objects dimensional objects,
we cannot see true 2 or 4 dimensions.
example 2 dimensions a sheet of paper, side on becomes invisible (length and width, but no height) we would always see if height on, making it invisible.

we can be the only one, we may not exist at all, but just somethings imaginary dream, or we can be a vast array of existences

Answer 6

by the very phrase a non-universe could not exist - you might have one where the big bang (if it did happen)did not have enough impetus to keep expanding so it would collapse in on itself, there may be many universes where life cannot exist in any form. You can't have a universe with nothing.
i have found that a cold cloth to the head works in these situations.

Answer 7

Dimentionallity seems to confuse people when it needn't.

Take a point in 'space'. This point exists in 0D (zero dimentions)
Now extend that point orthogonal to itself. It is now a line that exists in 1D (one dimention)
Now extend that line orthogonial to itself. It is now an area that exists in 2D (two dimentions)
Now extend that area orthogonal to itself. It is now a volume that exists in 3D (three dimentions)
Now extend that volume orthogonal to itself. It is now.....

... and here our perception of dimentionality collapses because we can't percieve more than three spatial dimentions, but mathematically this is perfectly acceptable and this fourth dimention has been equated to the dimention of time axiomatically.

Now extend this shape orthogonal to itself... and mathematically this is possible, now we are in 5D.

You can mathematically do this operation as many times as you like and it is still true. The sad fact is that science fiction jumped on this and destroyed the concept of dimentionallity. However, do this simple experiment:

Take a sheet of paper and stick a pin through it. Now bend the paper and stick the same pin through a different point in the paper. This object (the pin) exists in the two different points in space (2D here) at the same time. Now if you pull the pin out you have a hole running from one point on the paper to the other that you can make a pin almost-instantly warp from one point on the 2D space to another faster than the speed of the pin could possibly move if it was travelling within the 2D sheet of paper.

This is the principal that allows quantum entanglement occur superluminously, but instead of having a 2D plane of existance we percieve a 3D plane of existance and the pin (the information from one quantum particle to another) can pass through this higher-dimentional space.

Now, one of these dimentions could be percieved as alternative realities but it wouldn't be in the sci-fi way. Just as the peice of paper when viewed from above has an area, another sheet of paper below could equally exist and a pin could pass through both of them at the same time. This is what makes the theory of time travel possible.

I should, however, point out that only string theory has come close to describing the nature of these dimentions and the axiom that orthogonal extention leads to super-dimentional space isn't as simple as I have made out.

This should, however, give you some basic beginning step to help you understand why your 'infinite number of universes could mean that there is a non-universe somewhere' gibberish. For a start, it is believed that this super-dimentional space is defined not by the speed of light (as in our perception of 4D space) but the speed of gravity (which in 4D IS the speed of light, but is different in superdimentionallity).

Answer 8

No there can't be any 'non-universes' or places of absolute nothingness because by their own definition if they did exist - they wouldnt.

Get it?

Answer 9

yes, and the portal to the non universe is by swallowing the worm at the bottom of a bottle of Mezcal.

Answer 10

yup exactly. but we'll never know.

heres something to pickle your head - is there such a thing as 'nothingness'? nothingness is the absence of any sort of particle/object/atom/whatever, but if we can define something as 'nothing', then surely there must be something there? otherwise we wouldnt be able to define it :)
