2:44 "You probably know what the pion is" *awkward grimmace/smile "Yeah, totally!" lol

9:50 speculating here but, maybe Nima just solved the problem here.... What if modified gravity turns out to be retrocausal. That's why we won't be able to solve it. I hope that's not true, would love to solve this mystery.

Thank you. Wish I could be there.

Could it be that Nature is constantly performing a quantum eraser experiment on the vacuum energy and thus allowing for a tiny loop hope for what would otherwise be acausal? After all, the exchange symmetry has no "range" in space or time!

If G_newton where to vanish at some very high energy (small scale) would the spin 2 problem go away?

What If there isn’t... What If It’s just something we imagine, by observing, like the observer effect suggests

After watching this, I realize, I'm a dummy.
