Simply lovely! A bunch of big-brains have invented a giant equation that uses math to prove how math relates to other math. The best thing about it is how normies can so easily be fooled into thinking it's special.
The fact is: the universe doesn't give a fuck how we choose to describe it. This equation doesn't "solve" the universe and how it really works, it just unifies all the math that's been developed to describe how we THINK it works. Probably, it'll be wrong, strictly based on precedent that every other theory through thousands of years of recorded history has been wrong.
But unlike the universe, human hubris has no limits. THIS TIME, for sure, we've got it all right.
