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 Question regarding entanglement
@YogiDMT: It is indeed FTL, but that isn't a problem and doesn't conflict with special relativity or any other of our theories. I don't understand what you mean by entanglements implication of space not meaning what we think it means. The theory that describes entanglement is formulated in Minkowski spacetime, which is exactly what we think spacetime is (well, flat spacetime, we don't yet have a theory for dealing with entanglement in curved spacetime).

comment How electric field can be less than force per unit test charge?
@Nandhakishore: the positive charge will still polarise the ball, so it will reduce the density of positive charge on the near side of the ball and increase the positive charge on the far side of the ball. This increases the average distance between the test charge and the charges on the ball, so it will decrease the force.

@Nandhakishore: would you like to speculate, given the discussion in my answer?

comment How electric field can be less than force per unit test charge?
No, it just means the force on the charge will be infinitesimally small. All we are doing is taking the limit of $F/Q$ as $Q \rightarrow 0$, i.e. basically calculating $dF/dQ$. The ratio remains non-zero even as $Q$ and $F$ both tend to zero.

comment Treating matter waves as light waves?
No, because the group velocity of the matter wave will always be less than $c$, while the group velocity of light is always equal to $c$.

comment How did the Moon survive next to the Earth since earth and Moon came into existence?
@IgnorRamus: that needs to be a new question, thought you should Google around for theories describing the formation of the Moon to help you post a focussed question.
