Is it possible that black holes create dark matter/energy?

In summary, the conversation discusses the possibility of black holes creating dark matter and dark energy from the matter and energy they consume. It also touches upon the idea that inflation may slow when supply is low, supporting the theory that "everyone poops." Time dilation is then brought up as a potential factor in this process. The conversation concludes by mentioning various conjectures and opinions about the fate of matter drawn into black holes and the eventual evaporation of black holes in the distant future. However, there is no conclusive evidence or theory that suggests ordinary matter is converted to dark matter in this process.

Wondering if it's possible that black holes create dark matter and dark energy from the matter and energy they consume. Then, inflation might slow when supply is low. This would support author Tarō Gomi's theory that "everyone poops." What role would time dilation play if that's what's happening? Lastly, do black holes evaporate once their surrounding galaxies have been completely pulled in or do they remain?

Nobody knows in any detail what happens to matter that has been drawn into a black hole.
There are various conjectures mostly based on math which is known to be incomplete, and to a lesser degree on particle physics that we do know about, for example results from the LHC experiments.
As far as I know none of these conjectures or observations lead to the conclusion that ordinary matter becomes converted to dark matter.

On your last point, one fairly widely held opinion is that in the unimaginably distant future there will be nothing left in the universe other than black holes which will over an even more unimaginably long time evaporate, after which the universe consists only of a sea of extremely low level radiation.

Please remember the Physics Forums rule about personal theories and speculation unsupported by publication in appropriate peer-reviewed sources. This thread is closed, as there little to add to what rootone has already said: "As far as I know none of these conjectures or observations lead to the conclusion that ordinary matter becomes converted to dark matter."
 

1. What is dark matter/energy and how is it related to black holes?

Dark matter and dark energy are two mysterious substances that make up about 95% of the universe. Dark matter is a type of invisible matter that does not interact with light, while dark energy is a force that is believed to be responsible for the accelerating expansion of the universe. Scientists theorize that black holes may play a role in the creation of dark matter and energy, but this is still an ongoing area of research.

2. How could black holes create dark matter/energy?

One theory is that when matter falls into a black hole, it gets shredded into smaller particles and high-energy radiation. These particles may then interact with each other, forming new types of particles that could be considered dark matter. Additionally, the immense gravitational pull of black holes may also create dark energy through the stretching and warping of space-time.

3. Is there any evidence to support the idea that black holes create dark matter/energy?

While there is still much to learn about the relationship between black holes and dark matter/energy, there is some evidence that supports this idea. For example, observations of the rotation of galaxies suggest the presence of large amounts of invisible matter, which could be dark matter. Additionally, the accelerating expansion of the universe, which is attributed to dark energy, could be influenced by the presence of black holes.

4. Could black holes be the sole source of dark matter/energy?

It is unlikely that black holes are the only source of dark matter/energy in the universe. While they may play a significant role in their creation, there are other potential sources such as particle collisions in the early universe or interactions between particles and dark energy. Furthermore, there is evidence that suggests the presence of dark matter/energy in areas where there are no black holes present.

5. How does studying the relationship between black holes and dark matter/energy benefit us?

Understanding the connection between black holes and dark matter/energy can provide valuable insights into the fundamental workings of the universe. It can also help us to better understand the properties of black holes and possibly even find new ways to detect and study dark matter and energy. Furthermore, this research could potentially lead to advancements in our understanding of gravity and the laws of physics.
