It is a riddle, - where did thousands of atoms disappeared in the “bose-nova implosion” of cold bosonic gas.
Supposition A: A microscopic black hole was formed and it was immediately evaporated; the process of evaporation was accompanied by multiple barion-lepton annihilation.
Supposition B: Thousands of gas particles condensed into solid or liquid droplet and it was lost by experimentalists.
The answer to your riddle is rather easy. Imagine you look through a microscope at some object on the slide. Then someone suddenly bumps against the table, and the object disappears. Would you assume that a micro black hole just ate your object? No, of course not. Same thing happened here. The observation methods are focussed at the spot where the BEC forms. If you add 1/100th of the energy of a candle flame into the BEC, it will immediately disperse, and to the observer the atoms will have "disappeared".
Yes, according to me, the probability of A is much much less than B. But I can not exclude this possibility. Subnuclear condensates are much more real and are extremely dangerous. I fear just the subnuclear condensates.
Sidenote: What's a baryon-lepton annihilation? A baryon hits a lepton and both annihilate? If you can prove that, you got the next Nobel prize for sure ...
Did you heard about baryogenesis in the wrecked Big Bang model? I think that baryons and leptons are born by pairs there. If baryogenesis is possible, then baryocide is also possible. In fact, not bariocide, but baryo-lepton annihilation, because of the existence of the next obligatory reaction.
Did you heard about a monopole magnetic catalyses of proton decay?
Some theorists wrote the formula M + p = .. = M + e^+, where M – magnetic monopole; p – proton; e^+ positron.
If you wrote the next reaction, you will see the “baryon-lepton annihilation”, e^+ + e^- = photons.
Some theorists are dreaming to receive the energy from this “annihilation source of energy”.
But I said that this source of energy will work from 1000 seconds to 1000 days, because the first formula is incorrect. I would rewrite it in the form:
M_{n} + p = .. = M_{n+1} + e^+, where M is magnetic
dipole; index near M is the number of bosons in dipole magnetic hole. If you subscribe to this unknown boson the barionic number, equal to 1, and leptonic number, equal to 1, then the laws of conservation of barionic and leptonic numbers would be conserved. This my supposition is more preferable in my 4-d rotating model of Universe. I hate religious BB-dogma.
Bigbangers try to test their religion at LHC and thus they are ready to kill our world.
