Query: Neutrino and Extra World   The neutrino speed measurement experiments are the continuations of the
classic light speed measurement experiments have been done in range of the
solar planet system (Ole Roemer, 1676), in star system (James Braidely, 1728)
and, at last, on the Earth (Lois Fizeau, 1849),.... The finite light speed
measurement has led to the revolution in the humanity consciousness and
eventually led to a new understanding of the visible universe. In 1998-2005, we
had a lot of excited discussions at CERN about the possibilities to perform the
neutrino experiments to test the superluminal neutrino hypothesis and to find
new phenomena beyond the SM. From one hand the idea of such experiments was
associated with the hope to understand the role of the V-A- weak interactions,
the quark-lepton family symmetry, the neutrino space-time properties and to
observe some indications on a new vacuum structure existence outside of the
Weak Scale, i.e. in the region 1/R ~ (0.1-20) TeV. From another hand the
general trends of this idea has been related to the possible existence some
extra space-time noncompact dimensions of the universe. In this context it
would be first serious encounter with the dual conception between the physical
phenomena of microcosmos and of universe. One of the main goals is to find some
new space-time peculiarities and structures that might explain the formation of
our visible D=(3+1)-universe with all its space-time and internal symmetries
which could be only a part of a vast Universe filled with other kinds of
matter. The main difficulties of such experiments related to the possible
relativity principle paradoxes have been discussed.
