	  Sazetak: We propose a model for dark matter in which the dark
matter consists of orange-sized balls
of highly compressed ordinary matter. It is much like a small white dwarf
stars compressed
by a skin separating two phases of the vacuum. These balls have each a mass
around 10^11
kg. The one of the two possible phases of vacuum realised inside the balls
is characterised
by a bose condensate of a certain bound states (t-balls) each consisting of
six top quarks
and six anti top quarks. The whole model of ours is inside the Standard
model, except that
we propose a fine-tuning principle called "multiple point principle"
assuming that there are
several (almost) degenerate vacua. This principle is also helpful with
respect to the hierarchy
problem.
