Uniform background dust of plank mass black holes.

In summary, the conversation discusses the possibility of a significant amount of mass in the early Universe being made up of a uniform dust of plank mass black holes, in addition to the visible matter of our present universe. The conversation explores the potential evolution of this dust and its impact on spacecraft and humans. Additionally, there is speculation about the evaporation of black holes and their composition. The speaker is primarily interested in understanding the dynamics of these black holes in the past and present.

Say our early Universe had a significant fraction of its mass in the form of a uniform dust of plank mass black holes, along with the visible matter of our present universe. How might you figure such a dust would evolve in our early universe to our present epoch? Would such a dust clump just like ordinary matter? How would such dust effect spacecraft or humans? Would a plank mass black hole hurt if it passed through me?

Thanks for any help!

They'd evaporate instantly.

Let us assume they don't, it is just conjecture they do? We have never seen a black hole evaporate, maybe they don't?

Thanks for your reply!

What would these black holes be made of?

I was more interested in their dynamics, so let's just say they existed in the past and figure out their dynamics past and present.

Thanks!
 

1. What is uniform background dust of plank mass black holes?

Uniform background dust of plank mass black holes refers to a theoretical concept in astrophysics where there is a homogenous distribution of black holes with masses equal to or close to the Planck mass throughout the universe. These black holes are thought to have formed during the early stages of the universe and could potentially contribute to the dark matter content of the universe.

2. How are these black holes detected?

Currently, there is no direct way to detect plank mass black holes as they are too small to be observed with current technology. However, scientists can infer their existence through their gravitational effects on surrounding matter or through studying gravitational waves.

3. Why is the study of plank mass black holes important?

The study of plank mass black holes is important because it can provide insight into the early universe and the formation of black holes. It can also help us understand the role of black holes in the evolution of galaxies and the overall structure of the universe.

4. Can plank mass black holes pose a threat to Earth?

No, plank mass black holes are too small to pose a threat to Earth. They are also thought to be highly unstable and would likely evaporate rapidly due to Hawking radiation.

5. What are some current theories about the origin of plank mass black holes?

One theory is that they were created during the Big Bang, while another suggests they could have formed from the collapse of massive primordial stars. There is also the possibility that they are remnants of high-energy collisions in the early universe.
