Explaining blackholes dark matter ?

In summary, the conversation was about achieving absolute zero and Einstein's condensate theory. Scientists are using intense magnetic fields and light waves to reach near zero temperatures, but it would take a lab the size of the universe to reach absolute zero. This could potentially explain the event horizon of a black hole at its center. The discussion also touched on dark matter and its potential connection to atomic condensates. In the program, the achieved near zero condensates showed interesting properties, such as causing light to slow and act like it was moving through a field of ballistics gel. However, this is an effective speed of light, not the actual speed of photons.

Ok so i don't know squat about either subject, so blame Nova for this post. The show was talking about reaching absolute zero and einstine's conensate theory. As they talked about using intense magnetic fields and shot light waves through these near zero gas clouds causing light to slow. one scientist said while they can get close to zero it would take a lab the size of the universe to get to absolute zero. It came to my mind that this may explain the event horizon of a black hole at its very center and or dark matter/ lost matter/ in the form of atomic condensate of undiferentiated mass at asoulte zero. Anybody have some hard (theory) science to speak from on the subject.
In the program the near zero condensates they did achieve did have some interesting properties like causing light to slow and act like it was traveling through a field of ballistics gel only it would speed up when it got to the other side. very cool stuff ! pardon the pun.

A black hole is a vacuum solution to Einstein's equations of general relativity.
and or dark matter/ lost matter/ in the form of atomic condensate of undiferentiated mass at asoulte zero. Anybody have some hard (theory) science to speak from on the subject.

Normal matter, e.g., cooled rubidium atoms, is used to make the condensate, but theoretical and experimental indicate that dark matter isn't made from normal matter.

This is an effective speed of light, not the speed of photons. See

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and collapses under its own gravity.

2. How do black holes form?

Black holes form when a massive star runs out of nuclear fuel and can no longer support its own weight. The star then collapses under its own gravity, compressing its matter into an infinitely small and dense point known as a singularity. This creates a black hole.

3. What is dark matter?

Dark matter is a type of matter that does not emit or interact with light or other forms of electromagnetic radiation. It is believed to make up about 85% of the total matter in the universe and is thought to play a significant role in the structure and formation of galaxies.

4. How are black holes and dark matter related?

Black holes and dark matter are not directly related. However, black holes can indirectly reveal the presence of dark matter through their effects on the motion of surrounding stars and gas. Dark matter is also thought to contribute to the formation and growth of supermassive black holes at the center of galaxies.

5. Can we see black holes and dark matter?

Black holes cannot be seen directly, as their strong gravitational pull does not allow light to escape from them. However, we can observe their effects on surrounding matter and radiation. Dark matter cannot be seen directly either, as it does not interact with light, but its presence can be inferred through its gravitational effects on visible matter.
