thursday over all possible spin foam configurations

[Ming the Merciless]

Can someone explain to me what the feck this thread is about?

It‘s about the evolution over time of spin networks from Loop Quantum Gravity. This becomes spin foams.

In essence, spin foam configurations are the fundamental building blocks and the dynamical histories of quantum spacetime in Loop Quantum Gravity. They provide a non-perturbative, background-independent way to describe gravity at the quantum level, where the familiar smooth spacetime emerges as an approximation at larger scales.

I thought the N & L reunion extravaganza and BBC radio obsession are going to play in Embra. Ok, having to walk to and fro Murrayfield might be annoying, but nearer than Cardiff shirley?

Today's GP appt conveyed good news: all bloods counts, checks etc showing numbers within normal ranges. Which is nice. Not so good news: so why am I so bleepin' tired all the time? Body getting old and slower to rebuild itself? Eat more red meat? Keep licking those iron railings? Will up the multivits etc, see if that helps.

Anyway, today's pottering done for, time to get back to Glasto. Currently is Jalen Ngonda, cracking voice.

They could only get tickets for Cardiff (or so they said - could have just been a ploy to get a child free weekend away 😬)
I wouldn't give N&L any of my money personally.

Thanks for the excellent and clear explanation.

Yeah.
I read it to Beans.

Errrrr, Mornington Crescent?

This Mornington Crescent?
