Black hole expansion in the LHC?

Click For Summary

Discussion Overview

The discussion centers around the possibility of creating minuscule black holes in the Large Hadron Collider (LHC) during particle collisions, exploring whether multiple black holes can be formed in a single collision event, and if they could merge and grow. The conversation touches on theoretical frameworks, energy requirements, and implications of black hole behavior in high-energy physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants question whether the LHC can create more than one black hole in a single collision, suggesting that the energy limits currently do not support this possibility.
  • Others propose that if multiple black holes were created, they could merge and grow, although this is contested by participants who argue that the conditions for such events are highly unlikely.
  • A participant mentions the "Gravity's Rainbow model," suggesting that it requires higher energy levels than currently available at the LHC for black hole creation and merging.
  • Some participants express skepticism about the validity of the Gravity's Rainbow model, indicating that it is not widely accepted and may not be relevant to LHC experiments.
  • There are discussions about the nature of black hole merging in general, with some asserting that while black holes can merge, the specific conditions at the LHC make this improbable.
  • Participants correct each other on terminology and the framing of theories, emphasizing the need for precise language in scientific discussions.

Areas of Agreement / Disagreement

Participants generally disagree on the feasibility of creating and merging multiple black holes in LHC collisions, with various viewpoints on the implications of theoretical models like Gravity's Rainbow. The discussion remains unresolved regarding the potential outcomes of black hole interactions in the LHC context.

Contextual Notes

There are limitations regarding the assumptions about energy levels required for black hole creation and merging, as well as the definitions and interpretations of theoretical models being discussed. The conversation reflects a range of speculative ideas without consensus on their validity.

Greetings,
I am new to this forum and would like to present a discussion.

If a miniscule black hole is created in the LHC. Is it probable the LHC is capable of creating more than one black hole during a single event collision?

Considering fact and theory provided by credible research. Could it be possible for these micro black holes to merge and grow?

Perpetual expansion, not only through a merger, but also become larger through information it has collected? Let's say from the data received from the collision itself?

No. Physicists hope to produce a few (tens to thousands) black holes in something like 1015 collisions. Also, the current lower limits on the minimal black hole mass (based on previous collisions) tell us there is not enough total energy for two black holes in the same collision.

Even if the LHC had enough energy it would not make a difference. The total black hole mass, independent of the production process, is limited by the collision energy of the protons, and it is tiny - even if the whole collision energy would be used for the black hole it would evaporate immediately.

That does not make sense.

Thank you for your reply MFB...

Providing the previous attempts at LHC, Gravity's Rainbow model suggests they will need to increase the energy level from 5.3 TeV, to anywhere between 9.5 TeV in six dimensions - 11.9 TeV in 10 dimensions.

If the parameters of Gravity's Rainbow are accurate, LHC would have to modify the geometry of space and time near the Planck scale.

If this theory is accurate, it is said, "mini black holes have a minimum radius, below which they cannot shrink."

Therfore the mini black hole would not simplyevaporate.

Based off of theorized data, 2 miniscule black holes would merge causing the singularity to increase in size, so Yes.

What is a "Gravity's Rainbow model"? There is a book with this name but that is unrelated fiction.

The LHC collisions happen at 13 TeV this year.

Reference please?
 
Forum threads are not proper references, but I think "black holes can merge in general" is well established. For the LHC it would not matter.

"Gravity's Rainbow model" is a theoretical study attempting to debunk Einstein's theory of "Space Time." The theory seeks to prove: space is infinite, with no beginning or end. Therefore, no "Big Bang.

The LHC will be seeking evidence of the rainbow model in their next collision.

Yes, in general they can merge. But in the LHC you would need to make two from the same collision (already incredibly rare) and have them last long enough to merge (unlikely) and be produced with low relative angular momentum (also unlikely). I don't know of any prediction, but it must be incredibly unlikely/

Scientists use different language. They say "explore alternatives to General Relativity". "Debunking Einstein" is how crackpots talk, which is why you won't find such language in Ali, Faizal and Khalil. Furthermore, they build on Einstein rather than replace it: this is an attempt to generalize doubly special relativity to include gravity.

Okay, I found a reference for that model.

It is not.

Well, not really. The experiments look for signs of microscopic black holes. If they are found, then it might be possible to rule out multiple ideas how gravity and quantum mechanics might be unified. Some theories (probably more than one) will survive those tests. It is unclear which theories will be better.
Microscopic black holes at the LHC are quite exotic, and this particular model is even more exotic. "The LHC will be seeking evidence for this particular model" is a bit far-fetched.

To make it worse, the inventors of this idea predict that the LHC energy is not sufficient.

In future, could you please use the correct phrase 'based on' ,which actually makes sense.

Things are not 'based off' anything, and definitely not 'based off of'.
