    "Orange sized mountain heavy balls of alternative matter filled as
white dwarfs making up dark matter"

      Vrijeme:  23. rujna 2010. (četvrtak) 15.00, c.t.

      Sažetak: We have suggestively calculated that the interaction by
Higgs exchange
of 6 top quarks and 6 anti top quarks is so strong that they would with
a top Yukawa coupling being 1.02 plus minus 14 percent bind so strongly
as to form an almost zero mass bound state. It is discussed to observe
this 
bound state in coproduction with top quark pairs in LHC.
Actually we claim that it might have been already seen with insufficient
statistics at the Tevatron. Most important in our philosophy is it that
a Bose condensate of these bound state shall form a degenerate vacuum
with the 
vacuum in which we live, now. In a time inside the first fraction of a
second of the Universe it is suggested that this bose condensate were
prevailing over all. Then a phase transition occurred and now
in most of space there is no bose condensate. Only a tiny amount of
volume
inside some orange sized balls is still occupied by the old vacuum
(i.e. the bose condensate). These balls are spanned out by ordinary
matter in a state much like that in white dwarf stars, pressed together
by the force from the skin separating the two vacua. It can be fit
that these balls make up the dark matter and likely one ball fell down
in Tunguska 100 years ago.
