In the discrete
space-time geometry tachyons have two unexpected properties: (1) a single
tachyon cannot be detected and (2) the tachyon gas can be detected by its
gravitational influence. Although molecules (tachyons) of the tachyon gas moves
with superluninal velocities, the mean motion of these molecules appears to be
underluminal. The tachyon gas properties differs from those of usual gas. The
pressure of the tachyon gas depends on the gravitational potential and does not
depend on temperature. As a result the tachyon gas may form huge halos around
galaxies. These halos have almost constant density, and this circumstance can
explain the law of star velocities at the periphery of a galaxy. Properties of
the tachyon gas admit one to consider it as a dark matter.
