Bonjour à tous alors voilà
jusqu'à maintenant j'entendais souvent parlez du lhc et de ses risques notamment à propos des mini trou noirs.
Mais l'un des arguments était de parler des étoiles à Neutron en disait que si un mini TN pouvait se créé à partir d'un rayon cosmique il engloutirait l'étoile.
Or je viens de tomber sur un rapport qui dit ceci :
"Sixth offered new feature: Quantum protection for neutron stars
If only human-made ultra-slow mini-black holes can possibly pose a threat to earth through getting
stuck, their natural-borne ultra-fast cousins still ought to get stuck inside neutron stars, owing to the
latters‘ ultra-high density. Neutron stars should therefore no longer exist, apart from the most recently
born ones, if miniblack holes do exist and pose a risk. This is CERN’s strongest safety argument.
But, alas, neutron stars happen to be protected by quantum mechanics: The well-known superfluidity
of neutron stars prevents any friction from being exerted on a fast miniparticle entering them – so that
it will not get stuck but rather pass right through [13]. And if one were to get stuck in the (nonsuperfluid)
crust, the accreting black hole formed in the crust will soon stop growing since the star’s
superfluid bulk remains immune. The implied long-term “depilation“ of an originally broad-crusted
neutron star may be astronomically observable.
The prediction of “frictionlessness toward passing fast miniparticles,“ made for superfluids [13],
can by the way be empirically tested in the lab: on superfluid helium, serving as the target, and
neutrinos being used as the bullets (for example), with normal-fluid helium acting as a control [14].
This novel experiment can only be done at CERN since the latter harbors the largest amounts of
superfluid helium on the planet [14]. Thus if ever a dangerous aspect of a planned major experiment
could be tested beforehand in a safe auxiliary experiment, the LHC presents the prime example."

Donc j'aimerais avoir l'avis éclairer des gens présent sur ses forums
