Out of Pod Experience

it's interesting, but
a far too sensible and complex subject for GD
you will make the trolls damage their brain cell with that kind of information.

This breakthrough goes far, far beyond rendering easier Feynman diagrams. Quantum gravity might be at the brink of being expressed in a single formula for the first time. In the near future, we may well speak of the three great epochs in theoretical physics as Newtonian, Einsteinian, and Amplituhedronian.

This calculus crystal constant is a BFD.

Puzzling Thoughts

Locality and unitarity are the central pillars of quantum field theory, but as the following thought experiments show, both break down in certain situations involving gravity. This suggests physics should be formulated without either principle.

Locality says that particles interact at points in space-time. But suppose you want to inspect space-time very closely. Probing smaller and smaller distance scales requires ever higher energies, but at a certain scale, called the Planck length, the picture gets blurry: So much energy must be concentrated into such a small region that the energy collapses the region into a black hole, making it impossible to inspect. “There’s no way of measuring space and time separations once they are smaller than the Planck length,” said Arkani-Hamed. “So we imagine space-time is a continuous thing, but because it’s impossible to talk sharply about that thing, then that suggests it must not be fundamental — it must be emergent.”

Unitarity says the quantum mechanical probabilities of all possible outcomes of a particle interaction must sum to one. To prove it, one would have to observe the same interaction over and over and count the frequencies of the different outcomes. Doing this to perfect accuracy would require an infinite number of observations using an infinitely large measuring apparatus, but the latter would again cause gravitational collapse into a black hole. In finite regions of the universe, unitarity can therefore only be approximately known.

Very interesting finding, though at the end they fall into the trap of timelessness. Space may not be fundamental but I believe time is, though Lee Smolin's explanation of why lacks rigor for my tastes.

Then try Julian Barbour's "The End of Time"

Time can't be fundamental as it indeed does not exist. It's all just changing configuration states.

Or, at least that's what I'm convinced of currently.

I hate it- every time a major scientific breakthrough is announced I discover that I am apparently far too dumb to understand it.

Still..time-space-quantum-gravity thingy sounds pretty impressive.
