This was an interesting read - reminded me of another article [1] I read in 2013 about using a high-dimensional 'jewel' to describe reality, which then turned out to be an extremely efficient way to do the calculations from a Feynman Diagram. I'm still holding out hope that a unified theory will be found within my lifetime, and that these kinds of math will hold the key.

- jacknews 7y agoI believe this is somewhat controversial
- m12k 7y agoThat was an interesting read! Interestingly, John Baez, author of the originally posted link is also quoted in it.
- vankessel 7y agoI personally think that the split-octonions[1] hold promise for physics. The subset of the split-octonions where the i, j, k, and l components are 0 have a metric that is similar to that of Minkowski space[2]. (t + xli + ylj + zlk) * (t - xli - ylj - zlk) = t^2 - x^2 - y^2 - z^2 [1] https://en.wikipedia.org/wiki/Split-octonion https://en.wikipedia.org/wiki/Split-octonion [2] https://en.wikipedia.org/wiki/Minkowski_space https://en.wikipedia.org/wiki/Minkowski_space

- danbruc 7y agoIf you are interested in this, there are quite a few lectures by Nima Arkani-Hamed available on YouTube. From some aimed at the general public about the big picture of fundamental physics and the unresolved issues in it to pretty technical discussions of the amplituhedron and the related physics.
