Summary
The
Galactic Rotation Curve
describes the variation of
Orbital velocities of stars
and
Gas in a galaxy
as a function of their
Distance from the galactic center
. Observations of
Flat rotation curves
in
Spiral Galaxies
provide
Strong evidence for the existence of dark matter
, as the
Visible mass
alone cannot account for the
Observed rotational speeds
.
