Linky: Garrett Lisi may have solved Grand Unified Theory of nature.
General Story
To sum up: recently solved
E8 Lattice (the most complicated
Lie Group), whose solution is 60 gigabytes (compressed) apparently matches very well with our current theory of subatomic particle & strong / weak / electric forces theory. Lisi proposes 20 new particles to fill out the lattice, which he claims describe gravity. To date no particles that cause gravity have yet been detected.
You can watch a
Youtube video describing the theory in relative layman's terms here.
