String theory has an answer. Nth dimensional blobs of energy called branes. I don't to pretend to understand the math behind it, but its a neat theory.
I believe you are referring to Brane cosmology, which has some neat aspects to it, but based on my (limited) knowledge as some one who enjoys physics as kinda a hobby, I find it uncompelling. The math involved however is way over my head, so take that for what it is worth.
Brane cosmology originally evolved partly from the work of [ame="http://en.wikipedia.org/wiki/Twistor_theory"]Twistors[/ame] by Roger Penrose, Hawking's partner in black hole radiation (Hawking radiation). Twistors defined time and space around them.
What is so interesting to me are the scales of matter:
- an atom is 10-10 m.
- a nucleus is 10-15 m.
- a proton is 10-15 m.
- an electron is 10-18 m.
- a quark is upper bounds 10-18 m.
- a string is 10-35 m.
- Planck length = 1.616252×10−35 m.
So an atom is 99.999% empty
A proton, made up of 3 quarks, is 99.9% empty
A quark, made up of several strings, is 99.9999999999999999% empty.
There is no such thing as matter. It is only empty space, energy and force.
