Gravitation

Gravitation is a phenomena that binds things with mass and energy with
an attractive force.

The earth have gravity, that gives weight to physical force. The moon
also have gravity, that creates ocean tides.

Gravitation among gaseous objects in universe starts coalescing and
forming stars.

In general theory of relativity, gravity is described. Here, gravity
described not only as a force, but as a curvature of spacetime caused
by uneven distribution of spacetime. Most example of spacetime
curvature is black hole from where nothing can escape.

Nertona law of universal gravitation describes gravity as a force
between two objects is proportional to the mass of two objects and
inversely proportional to distance square of the objects.
