New Discovery Simplifies Quantum Physics

This looks like a promising way to simplify the equations of the quantum world. It involves an infinite dimension model of the universe and should get rid of some paradoxes.

Personally I'm not comfortable about an infinite dimensional Universe and I didn't see anything in the article that would imply that. Nor did it say anything about paradoxes. Where did you come across these two concepts in regard to the paper?

Oh I missread the part of the article about paradoxes, it says that other unified theories are riddled with problems such as paradoxes, it doesn't say that this will rid us of paradoxes it just gives reason so doubt other unified theories.
The master amplituhedron which they are relating the universe to is infinite sided meaning an infinite dimensional space. The wikipedia article about this states it explicitly "the amplituhedron is a theoretical geometric object in infinite-dimensional space that dramatically simplifies calculations of particle interactions of some quantum field theories"

Most Physicists (myself included) view the "paradoxes" in QM to simply mean that we don't yet have a complete theory to work with. That's one of the big draws for String Theory...as far as I know it doesn't have any infinities in it. (Neither does N = 8 Supergravity.) But yes, we tend to sweep such problems under the rug, as it were.

I'll have to look into the amplituhedron. I've never heard of such a thing.

Thanks for the reply!
