Dark Matter Pearl able to make Heat  by Neutrons and help Supernovae

Sazetak:

We present an idea about how dark matter could appear - a bit complicated
though - in pure Standard model, only modified by adding to it a rule -
called Multiple Point Principle - for finetuning the coupling constants
(partly). With this fine tuning principle Colin Froggatt and I once
successfully PREdicted the Higgs mass ( before Higgs were found!).
In our model dark matter consists of pearl size extremely haevy pieces of a
new vacuum filled with material much like the one in white dwarfs kept
together by surface tension associated with the border of the two types of
vacuum. The weight of the pearl is about 100000 tons. Such a pearl can get
heated up - a new source of energy! - by being exposed to neutrons, about 10
MeV per neutron. This property makes it also a candidate for playing a role
in supernova explosions. Actually we postdict the time nce between ther
being TWO  strong neutrino bursts which were 4 hours and 45 minutes, we got
though 14 hours but with our accuracy that is the same.
