By well-known mathematical physicist John C. Baez. This refutes the article that floated around a few days ago saying the universe would end sooner than expected. That article was based on the premise that dead stars (big chunks of matter that aren’t black holes) emit Hawking radiation the way that black holes do, and that the matter in the universe would eventually decay through this mechanism. The linked blog post says that the premised is wrong, and matter in normal space doesn’t give off Hawking radiation. I guess in 1074 years (iirc) we will find out who was right!
This is a WordPress blog of some guy complaining that an academic study showed something he doesn’t think is true…
It’s by John Baez who is a very legitimate mathematical physicist who works in this area. See for example his “This week’s finds” series.
He does appear to be a professor in the field
I edited the post to add a wikipedia link.
It contains references the references to the rebuttals which are published in physics journals.
