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.

OK, OK, I'll explain why the speed increases with temperature. Sheesh.

I'm voting to close this question as off-topic because it doesn't make sense

possible duplicate of The speed of sound is proportional to the square root of absolute temperature. What happens at extremely high temperatures?

Hi Roshan. I wish you luck with your PhD, but this isn't a question about physics and is out of place on this site. You could try asking in the Physics chat room.

comment cosmological red shift significance in terms of success of gr
It's not clear what you're asking. Note that the development of GR predated the experimental discovery of the red shift.

comment When they say the universe was the size of a baseball about a billion billion billion billionth of a second
The point about infinite/finite is that an infinite universe cannot ever have been the size of a baseball because a baseball isn't infinite. I don't understand your point about the density fluctuating. According to the FLRW model the density has been decreasing smoothly since the end of inflation. During inflation the density is determined by the inflaton field, and we don't don't know how this behaved though it probably remained roughly constant during the inflationary era.

@Jaywalker: citations please. Your claim does not match my experience.

It means the observable universe. Assuming the universe is currently infinite in size it has always been infinite in size
