miniblack holes in CERN?

Question

its said that in the large hadron collider- CERN when experiment starts later this year miniblack holes will be produced.

If im not wrong there miniblack holes wont last for long and will evaporate due to Hawking radiation.

Can you please explain why the creation of these miniblack holes are important in the collider? what role do they play?

Answer 1

At first glance the production of black holes in colliders could be bad news. It could mean the end of particle physics since the presence of a horizon would obscure all the microphysics processes that could occur behind it. However, it would in fact open up very good opportunities.

It turns out that the reconstruction of temperature (determined by the energy spectrum of the particles emitted when the black hole evaporates) as a function of mass (determined by the total energy deposited) allows information to be gained about the dimensionality of space- time. In the case of Planck scales close to the TeV mark, the number of extra dimensions could thus be revealed quite easily by the characteristics of the emitted particles. However, one can go further. In particular, quantum gravity effects could be revealed, as behavior during evaporation in the Planck region is sensitive to the details of the gravitational theory used.

So this means we will have experimental evidence to prove or disapprove Superstring Theory, and other quantum gravity theories, such as Loop Quantum Gravity. Hence, the creation of these mini-blackholes in the LHC will have significant consequences in terms of allowing us to advance further our understanding of the Universe.

Answer 2

Becuase if ever we can make some, then it may confirm or weaken our present theories on small, and big, black holes.
