Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment How did the gravity of the particles/objects behave at the edge of the expanding universe moments after big bang?
See Excluding big bang itself, does spacetime have a boundary?. Spacetime didn't have an edge shortly after the Big Bang, and indeed has never had an edge.
