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 Doesn't dating the universe violate the concept of spacetime's inseparability?
Well, it's the time component of the comoving coordinates. Is abbreviating this to comoving time such a sin? You are of course correct that it is also the proper time of a comoving observer.

comment Are magnetic orbits possible?
The magnetic fields of the Sun and Earth have a negligably small effect on their mutual orbit. The orbit is dominated by gravitational forces.
