Instead of taking a tangental discussion even farther astray, let me start a new thread here.
seems to be a new computational tool to figure out quantum physics (and possibly quantum gravity).
IIRC, like Feynman diagrams, this construct acts as a mathematical shorthand, reducing pages and pages of equations into a few simple pictograms, or, in the case of the amplituhedron, ONE multidimensional faceted gem.
The Amp. manages to do away with Locality (spacetime) and Unitarity (all possible probabilities must add up to one).
What this implies is that space and time are NOT fundamental constituents of reality, but are constructed from something deeper and hidden.
Has anything new popped out of this tool in calculating Black Holes or the Big Bang?
