Asa Forsythe are you saying that he’s cute? ☺️ yes, he is 🥰.. He’s my fake brother ☺️🥰💋❤️😘💕

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

[@dmitryalexandersamoilov]

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.

[@StephenPaulKing]

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!

Thank you. Wish I could be there.

The cameraman (I assume it's a man) is in love with the girl with glasses

[@Apollyon-sz9sn]

The type of girl you'd like to smash hard! 🤟

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.
