The Meissner effect within a galaxy

In summary, the conversation discusses the possibility of a black hole being so compact that its individual particles cannot move, making it extremely cold and potentially exhibiting the Meissner effect. This could potentially explain the observed behavior of stars orbiting the center of galaxies and the concept of dark matter. However, it is noted that this idea is not supported by current knowledge and the influence of magnetic fields on the motion of stars is negligible.

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.
 

What is the Meissner effect within a galaxy?

The Meissner effect is a phenomenon in which a superconductor expels magnetic fields from its interior, causing it to act as a perfect diamagnet. Within a galaxy, this effect can occur in regions where there is a high concentration of superconducting materials, such as in the cores of stars or within galactic nuclei.

How does the Meissner effect affect galaxies?

The Meissner effect can have a significant impact on the behavior of galaxies. It can cause stars and other objects within a galaxy to move in unexpected ways, as the expulsion of magnetic fields can create unusual gravitational forces. Additionally, the Meissner effect can also influence the formation and evolution of galaxies, as the distribution of superconducting materials can affect the overall magnetic field structure of a galaxy.

What causes the Meissner effect within a galaxy?

The Meissner effect is caused by the interaction between superconducting materials and magnetic fields. When a superconductor is exposed to a magnetic field, it generates electrical currents that create an opposing magnetic field, causing the material to expel the original field. In a galaxy, this effect can occur due to the presence of superconducting materials, such as certain types of matter or exotic particles, that are capable of exhibiting this behavior.

Can the Meissner effect be observed in other galaxies?

Yes, the Meissner effect has been observed in other galaxies besides our own. It is believed that this phenomenon is a universal property of superconducting materials and can occur in any galaxy where these materials are present. However, due to the complexity of studying galaxies and their magnetic fields, further research is needed to fully understand the prevalence and impact of the Meissner effect in other galaxies.

What implications does the Meissner effect have for our understanding of the universe?

The Meissner effect is an important phenomenon to study in the context of our understanding of the universe. It provides insights into the behavior of superconducting materials and their interaction with magnetic fields, which can have implications for other areas of physics. Additionally, studying the Meissner effect within galaxies can also help us better understand the formation and evolution of these cosmic structures, and how magnetic fields play a role in shaping the universe as a whole.
