The Meissner effect within a galaxy

Main Question or Discussion Point

Is it possible that a black hole is so tightly compacted, that its individual particles are unable to move? If this is the case then wouldn't it be extremely cold; close to, or even at absolute zero? Any significant heat would be on the surface caused by friction of attracted matter. With such a cold body, specifically the super massive black hole at the centre of many or all galaxies, could it become a super conductor and exhibit behaviour observed with the Meissner effect and thus influence the orbiting stars and planets within the galaxy? It has been said that the speed of stars orbiting the centre of a galaxy cannot be justified taking into account their total mass and this led to the invention of dark matter. So, if the Meissner effect can have such an effect, considering that stars have a magnetic field, could it be strong enough to provide a boost to their speed?

No.

In addition, particles are not billard balls, they cannot "fill the space" like them. Neutron stars have some similarity to that picture, but those are very hot, and the particles can still move in there.

Concerning the other questions: no, as the basic idea is not right.
In addition, the scale is completely wrong. While there are magnetic fields in the galaxy, their influence on the motion of stars is negligible, and a small deviation from that field is even more negligible.
