It’s very odd to think of something extremely hot but with almost no density, and therefore very little heat transfer.

Temperature is a totally valid measurement. For physicists. Not really for clickbait articles. High energy particles wouldn't attract as many views.

If it were really that hot we'd never observe the CMB at a balmy 2.7K.
