"Maybe Space-Time Is Just an Illusion" - Amplituhedron
Posted: Sat Sep 21, 2013 2:00 pm
So it is a new thing every day that questions reality as we know it. I'm not talking about our LTP but theoretical physicists and other scientists who are continuing with Einstein's assertion that "reality is merely an illusion- albeit a very persistent one".
This article discusses the amplituhedron - physics is not an area of strength for me but these are interesting parts:
"Arkani-Hamed and Trnka discovered that the scattering amplitude equals the volume of a brand-new mathematical object — the amplituhedron. The details of a particular scattering process dictate the dimensionality and facets of the corresponding amplituhedron. The pieces of the positive Grassmannian that were being calculated with twistor diagrams and then added together by hand were building blocks that fit together inside this jewel, just as triangles fit together to form a polygon."
“They are very powerful calculational techniques, but they are also incredibly suggestive,” Skinner said. “They suggest that thinking in terms of space-time was not the right way of going about this.”
Some of you may understand the physics better than I do. Then, you can teach it to the rest of us
