Arthur C Clarkes "2061"
weirdly I was reading this last week (sleepless night) where the premise is diamonds can be created in gas giant type planets. I think there's a 1980s NASA paper on it ?
The source of unusual faint pockets of microwave radiation found only in a few regions of the Milky Way has been traced back to tiny specks of nanodiamond dust. A paper published in Nature Astronomy on Monday cracks the mystery of anomalous microwave emission (AME). It was first discovered in the late twentieth and early …
Are we sure this isn't a sign of Star Trek's crystalline entity?
"The radiation must represent a loss of energy so their spin should slow. Is there a mechanism to spin them up again?"
They seem to be mainly in protoplanetary discs, so the source of energy will be gravity - as the disc contracts gravitational potential energy is converted into kinetic energy, and some of this can be converted into spin (still kinetic energy, but individual rotation rather than bulk movement) through collisions.
"polycyclic aromatic hydrocarbon (PAH) molecules scattered throughout space."
Not possibly a remnant of the Big Bang, (originally coined as a derogatory term for the theory of rapid expansion from a singularity.)
but instead it may have been actually the 'Big FOO', a space fart leaving aromatic hydrocarbon distributed among the galaxies.
Nanodiamonds emitting micro & terra waves what was the driver stimulating the diamonds to emit?
