The heavier the body is, the stronger
its gravitational pull. Just like earth, we feel gravitational pull because we
are attracted to earth and so is the moon. Also, the sun is heavier than the
earth and therefore, we are attracted to the sun because of its gravitational
pull. When the earth revolves around the sun, both of them releases
gravitational waves. Gravitational waves are ripples of waves travelling
outward from the source. The more massive the orbit of two bodies, the more it
emits gravitational wave. And everything around it that is near within the wave
experiences a ‘pull’ toward the orbiting bodies. The advantages we get when we
can measure gravitational waves are; one, we can measure the activity between
two bodies in orbit in the universe, two, scientist can estimate the merging of
two bodies in the universe every 15 minutes by using LIGO and three, we can
know the behavior of other bodies that we did not know exist.
