Black Hole Formation in Proton-Proton Collisions

In summary, the formation of black holes in proton-proton collisions is a possibility that has been explored in the past. This idea was based on the concept of extra dimensions affecting gravity, resulting in stronger gravity at high energies. However, no black holes have been found at the LHC and this idea is considered highly speculative. A review from the Particle Data Group on searches for extra dimensions can provide further information on this topic.

Why do you think that this can happen?

i'am only talking about probablities so in ultra high energy collisions i think there is a probability of formation of black holes

Maybe you're thinking about the ideas from about 10 years ago where it was proposed that if there are extra dimensions which only affect gravity, gravity can be much stronger at high energies/small distances. For some values of the size of the extra dimensions there was a possibility that the LHC reached this energy and that the colliding protons would create a microscopic black hole.

This is one of the original articles examining BH production at the LHC:

This is one of the articles which proposed the extra dimension-scenario:

Of course, there hasn't been found any black holes at the LHC and many probably agree that these ideas were quite speculative.

1. How do black holes form in proton-proton collisions?

Black holes can form in proton-proton collisions when the energy of the collision is high enough to create a singularity, a point of infinite density, within the particles. This singularity then grows rapidly, pulling in more matter and creating a black hole.

2. What is the role of gravity in black hole formation?

Gravity plays a crucial role in black hole formation as it is the force that causes the particles to collapse into a singularity. In proton-proton collisions, the high energy of the collision overcomes the repulsive electromagnetic forces between the protons, allowing gravity to dominate and form a black hole.

3. Can black holes be created in any other type of particle collision?

Yes, black holes can potentially be created in any type of high-energy particle collision, not just proton-proton collisions. This includes collisions between protons and antiprotons, electrons and positrons, and even collisions at particle accelerators such as the Large Hadron Collider.

4. How is the size of a black hole determined in a proton-proton collision?

The size of a black hole formed in a proton-proton collision is determined by the amount of energy released in the collision. The more energy present, the larger the black hole that can potentially form. This is because the energy is converted into mass, which contributes to the mass of the black hole.

5. Is it possible for a black hole created in a proton-proton collision to evaporate?

Yes, according to the theory of Hawking radiation, black holes can emit particles and lose mass over time, eventually leading to their complete evaporation. However, this process is very slow for black holes formed in proton-proton collisions, and it would take trillions of years for them to evaporate completely.
