One of the Wonderful prediction
of Einstein’s theory was”Big Bang Singularity.” It says that everything come
out of a single event. He predicted gravitational waves in his general theory
of relativity a century ago. Under this, space & time are interlinked into
something called “Space-time.”
Einstein predicted that mass warps
space-time through its gravitational force. So how this gravitational waves
help us?
When Radio waves were discovered, we started
communication by using this waves. This has taken us to next step of
communication even at so far locations. Mobile communication is totally
dependent on radio waves. At the same time,for astronomy, radio observations
have probably given us more about the structure of universe. Likewise,
gravitational waves are going to give a whole new picture of universe, the
stuff that doesn't emit light-dark matter,black holes.

So
gathering gravitational waves will be able to see exactly what happened at the
initial singularity. Thursday’s announcement was the unambiguous detection of
gravity waves. There is a hope that gravity wave astronomy could start to
answer questions not only about the life of starts, but also about their deaths
as well. Death by collision,death in a black hole were explained.
Detectable gravitational waves open exciting
gates in astronomy. It allows measurements of faraway stars, galaxies and black
holes based on the waves they make. Partially, it also shows some evidence that
black holes which were never directly discovered,do actually exist.
