Discussion Overview

The discussion revolves around the potential dangers of the Large Hadron Collider (LHC) creating micro black holes as it operates at high energies, specifically 6.5 TeV per proton, leading to a total of 13 TeV in collisions. Participants explore the implications of these phenomena, including the Planck energy and the nature of micro black holes, while expressing curiosity and concern about the safety of such experiments.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express concern about the possibility of the LHC creating micro black holes and whether this poses a danger.
  • Others argue that similar high-energy events occur naturally in the universe without harmful consequences, citing cosmic rays as examples.
  • There is a discussion about the Planck energy, with some participants suggesting it could be lower than traditionally thought, potentially allowing for the creation of micro black holes at the LHC.
  • One participant questions the gravitational force of hypothetical micro black holes, suggesting it would be tiny compared to regular matter of similar mass.
  • Another participant emphasizes that if micro black holes were to form, they would evaporate almost instantaneously, negating any potential threat.
  • Some participants challenge alarmist views presented in media and online videos regarding the risks associated with the LHC.
  • There are inquiries about the time scales for micro black holes to absorb matter if they do not evaporate, with varying responses regarding the duration of such processes.

Areas of Agreement / Disagreement

Participants generally agree that the creation of dangerous micro black holes at the LHC is highly unlikely, but multiple competing views remain regarding the implications of their existence and the nature of their gravitational effects. The discussion remains unresolved on certain speculative aspects, particularly concerning the time scales for evaporation and absorption.

Contextual Notes

Some limitations in the discussion include a lack of consensus on the exact nature of Planck energy and its implications, as well as varying interpretations of the safety of high-energy collisions. The discussion also reflects differing levels of understanding among participants regarding complex physical concepts.

Who May Find This Useful

This discussion may be of interest to individuals curious about particle physics, the safety of high-energy experiments, and the theoretical implications of black holes in the context of modern physics.

Hi all,
I'm probably not the only one asking this
yet another question about the famous LHC, this accelerator
particles that will rise up to 6.5 TeV energy ...
That makes 13 TeV ... Does it have the potential to
create micro black holes, and this would be dangerous?
I asked some questions, everywhere, and was told
not (appriori ...) I am sorry to bother you with this kind
question, but here, I'm curious, and has both a little worried ...
I heard a lot about sizes with a famous
Planck energy, but what about? hoping that my poor
English translated understandable; i am french
I thank you in advance for your answers, cordially
 
Physics news on Phys.org
The Wikipedia article on the LHC explains this clearly.
The reports also noted that the physical conditions and collision events which exist in the LHC and similar experiments occur naturally and routinely in the universe without hazardous consequences, including ultra-high-energy cosmic rays observed to impact Earth with energies far higher than those in any man-made collider.
In other words, the Earth gets hit with far higher energies from space all the time and it hasn't been sucked into a black hole. :)

Also, don't believe everything that you read in the media, they usually get the science wrong.

Hi Borg,

Thank you for your reply!
I'm sorry for asking this question, but here, as said
above, with all the topics in the French forum I used
visit (futurascience) there was a lot of the same topic
question ... I had a little trouble to distinguish all the answers ...
I leave this topic open for other possible answers
thank you again

Good Saturday
Best Regards
 
I don't think you can find other possible answers. The stage is fixed:
http://press.web.cern.ch/backgrounders/safety-lhc
[it's just speculative theories that predict such productions- which of course will be harmless]

Media don't get science wrong. Media change the meaning of science because they refer to non-scientists and they want to sell.
 
Hello!

In any case thank you both
for your answers that reassure me in part
I am very happy to have registered this forum
 
hello,

I have one last question:
I just wish to know ... What is the Planck energy with and without dimension? And what has the smallest mass (micro) black hole?

Good Sunday to all,
 
The Planck scale is the energy scale at which gravity start becoming as important as the rest forces in elementary particles (so quantum gravity effects). In normal four dimensions as we know 'em, this scale is at M_{Pl} \sim 10^{19}~GeV.
The theories that predict the micro-black holes are in general theories that concern extra dimensions, which are diluting gravity (and that's why we see it so weak)... So the true Planck's scale would be smaller... so it could be down to some TeV(=1000GeV) and thus predict the black holes in LHC. However that's not the case anymore. Their mass would be equal to the same Planck Scale...
If it was diluted from 1TeV, then the black hole's mass would be 1TeV. If the Planck's scale was at 10^{13}GeV then the black hole's mass would be that... and so on...

Thank you for answering

I hope that he was not pushy, and I think at this stage,
with all the answers I got, I can say that
a micro black hole land swallower is almost impossible,
for example: the many yooboob vid and the famous "Cyriak.Com"

I wish you a good Sunday in advance :)
 
Hello,

I resume the thread to avoid unnecessary duplication
As I am a curious, and also a little worried
despite any solid answers common sense
I got here; I can not help but
wonder what would happen if these hypothetical
micro black holes do not evaporate ...
and what gravitational force would have this kind of object?
I do not know anything physical, being a merely curious
science, these microphones black holes would have a force
tiny gravitational?

Bon we to you all
Nitox

The same as regular matter with the same mass, which is at most 2.5*1020 g or the mass of a larger molecule. The corresponding forces would be tiny.

Let me rewrite my original post then.
In other words, the Earth has been getting hit with far higher energies from space for billions of years and it hasn't been sucked into a black hole.

Full of common sense answers
So I can say with certainty that
alarmist scenario (Cyriak, youtube) an outgoing black hole LHC
land swallower in minutes is almost impossible?
Sorry for all these questions, but I can not
not help but ask ...

Have a nice evening
Nitox :)

It is also impossible in years, or millenia, or whatever timescale you like.

Good evening, and good night ...
It remains for me to say
a big thank you to all those who responded
It contributes greatly to reassure me
I would can be other issues, but rather technical :)
I hope not to have too been insisting my questions
Good Sunday to all

Re hello here ...
Subsidiary Question ...

I thank everyone for giving me answered
Sorry if I asked a question about it, I wanted
why these micro black hole take as hypothetical
time to absorb the matter if it does evaporate (the answers I got french, millions or billions of years?) sorry again for Renewal
the subject, but here I can not help but continue to ask me
 
  • #16
I don't think that you're understanding the scales of time and distances involved.
 
  • #17
Such a microscopic black hole would evaporate faster than 0.0000000000000000000000001 seconds, long before it moves as far as the diameter of an atomic nucleus.

Hello everyone!
Thank you for responding, I hope not to have
was pushy with all my questions
