The beginning and the end

November 9, 2020

I heard a programme on Radio 4 (UK) today (Monday 9 November 2020: Start the Week with Roger Penrose, Carlo Rovelli and Helen Czerski, introduced by Andrew Marr), and I think I understood it as…

Once the Universe decays (transforms) into a form in which there are no baryons (particles with mass), but only photons which move at the speed of light, everything will be everywhere all at once, and spacetime will cease to exist. This could be interpreted as a collapse of all the energy in the Universe to a single point, whence the big bang starts (again? or just the once?)

I found this (i) comprehensible and (ii) wonderful.

Meanwhile, I’ve just put together the sponge mix that will turn into sourdough bread tomorrow. The beginning of a new loaf.

playing jazz in lockdown

November 7, 2020

sometimes i play jazz on jamulus, with other people: tonight with some bostonians though the latency was very high.

but now i’m back playing, late at night to the dog.

it’s more interesting jazz, less just standards, but monk stuff.

the dog seems happy enough.

more of an audience than we sometimes got even before lockdown.
