By newton's gravitational theory we see that each object is attracted to the earth by a gravitational force. Even in the universe, a gravitational force is present. The objects which are under attraction undergo movement.
Thus we can conclude that the universe is not static because of the movement by gravitational force.

In alternative language,
newtonian gravitational theory
states that the acceleration a (the
rate of change of the velocity v)
imparted by gravitation on a test
particle is determined by the
gravitational potential ,
a = -dv / dt = - ,
and the potential is determined
by the surrounding mass
distribution by Poisson's partial
differential equation
· = 4 G .
This formulation is entirely
equivalent to Newton's law of
gravitation. Because a test
particle's acceleration depends
only on the potential generated
by matter in the surroundings,
the theory respects the weak
equivalence principle: the motion
of a particle is independent of its
internal structure or
composition. As the subject of
Galileo Galilei's apocryphal
experiment at the tower of Pisa,
this principle is supported by a
series of high precision
experiments culminating in those
directed by Baron Lorand von
Eötvos in Budapest in 1922,
Robert Dicke at Princeton in
1964, and Vladimir Braginsky in
Moscow in 1972.
Highly successful in everyday
applications, newtonian
gravitation has also proved
accurate in describing motions in
the solar system (except for tiny
relativistic effects), the internal
structure of planets, the sun and
other stars, orbits in binary and
multiple stellar systems, the
structure of molecular clouds,
and, in a rough way, the
structure of galaxies and clusters
of galaxies
