Exploring the Possibility of Elementary Particles as Black Holes

In summary, there is currently no evidence or theory supporting the idea that elementary particles are small black holes. While it is possible for any particle to become a black hole with enough energy, the lower bound on black hole mass is the Planck mass, which is much greater than the mass of any known elementary particle. Additionally, the shape and surface of a black hole would not align with the properties of particles, and there is no evidence of Hawking radiation from particles.

Is there any theory for which "elementary" particles are "small" black holes or/and for which the electron and the proton would be a pair of associated black holes?

Does such question even be meaningful ? Or is it just science-fiction, the fruit of any crazzy imagination?

Any particle, given enough energy, will become a black hole

Are you saying that a particle can become a black hole by accelerating to a high velocity close to c? If that is what you are saying, then you are wrong.

Really? I thought that energy curves space-time, and when it gets curved enough it becomes a black hole. I mean, possibly ignoring new Planck scale effects

I'm quite confused here.. shouldn't a property of being a black hole be coordinate invariant?
There should be some singularity inside of horizon with some diverging scalar quantity.
Moving alongside the particle, no such singularity should be observed.?

That's addressing the converse of the question in the OP.

For an elementary particle to be a black hole, it must have a Compton wavelength smaller than its Schwarzschild radius, otherwise the horizon is not defined. The lower bound on the mass of a black hole is therefore the Planck mass. All known elementary particles are well below this bound, so they are not black holes.

Despite the recommanded document is treating the converse of the question, I shall read it... and perhaps ask some more new questions.

For atyy and fzero: thank you.

What is true is this complicated interplay between the mass (the equivalent proper energy) and the dimensions (in fact the geometry, the form and the exterior surface) of a given black hole.

I am no specialist about this thematic but I guess it must be an excellent way to test some fascinating theories concerning topology, quantization ...a.s.a...

One could for example ask why the "smallest" black hole (of which the surface must be quantized, accordingly to different works: Hawking, Rovelli...) is not a pyramid (just a funny proposition) insteed to be a sphere?

As non specialist, I see another objection to the possibility: particle = blac hole. Since some particles are radiating, this hypothesis -if true- would impose a coincidence between the observed radiation and the Hawking radiation which seems to be the only one authorized by the theory...
 

1. Can particles really be black holes?

Yes, according to the theory of general relativity, any object with a mass and a small enough radius can become a black hole. This includes particles, which can have a very small radius and therefore a strong gravitational pull.

2. How can a particle become a black hole?

When a particle has a high enough density, its gravitational pull becomes strong enough to overcome the forces that usually hold particles together. This causes the particle to collapse into a singularity, creating a black hole.

3. Are there any known examples of particles being black holes?

There are no known examples of particles being black holes in nature. However, scientists have created miniature black holes in laboratories using particle accelerators, providing evidence that particles can indeed become black holes.

4. Can black holes form from any type of particle?

Yes, any type of particle with mass can potentially become a black hole. This includes not only subatomic particles, but also larger particles such as atoms and even planets.

5. How does the behavior of a particle black hole differ from a larger black hole?

Particle black holes, also known as micro black holes, have different properties than larger black holes. They have a smaller mass and therefore a smaller event horizon, making them difficult to detect. They also evaporate and disappear much faster due to Hawking radiation, whereas larger black holes have a longer lifespan.
