Universe of nothing?

What might a universe be like with nothing in it? Or at least one composed of empty space? Would it have dimensions or angles? Discuss

Dimensions and angles are properties of space-time and a universe would have space-time. It would just be an empty arena with subatomic activity due to quantum fluctuations.
 
No space-time without subatomic activity.
Here one must make a concrete statement about "a space-time must have expansion", so that one can make a concrete statement that "an expanding universe must pass by in comparable size to a subatomic realm", so as to cause an "inevitable establishment of volumes of matter", so as to conclude, "all space-times must resemble the one we now inhabit, and call the universe".

If we assume that every universe in a multiverse landscape is fundamentally a quantum entity... then potential always exists.

"Nothing" - in the quantum sense - is unstable. Think about it.
 
nihilism.

Also with a multiverse where every possiblitiy is evenly distributed among it, God exists in about 1/2. And in the other 1/2, I am the multiverse.

This is a great question to start the dimensional visualisations ability maturing.
If there is nothing in it there can be no time.
If there is nothing in it it has no volume nor dimension.
If it has nothing in it you have a zero point.
the question then is how can you put something in something that doesn't exist?
exnihilio?
If you take everything out of it don't you just have what is commonly referred to as "unconsciousness"?
 
I do not think that such a universe could/would exist. It's a little like asking "what if one equaled zero?"

How can you justify space time with a universe that is empty of mass or any substance?
 
A photon at rest in the planck scale. I don't think the problem should be how you can remove everything to have nothing, but how can you add as much stuff as possible that would still be nothing with words to descibe it eventhough mathmatically it is still nothing, at least to us or an ordinary observer.
