Gravitational waves,LIGO and Einstein!



These days everyone is saying LIGO has found Gravitational waves , Einstein was true! but what is gravitational waves and what connection it has with Einstien?

Lets find what are Gravitational waves?

Gravitational waves are waves that are generated by massive objects like black holes. When this waves travel through the space it stretches and compress it.

What that means?

It means that whenever the waves passes through the object like me and you it compresses us and also stretches us. But don't be serious because this stretches are only at atomic scales.

But What connection it has with Eienstien?

In 1915 , Einstein gives most Precious theory of human life. "The general relativity"This theory states that space and time could be bend as fabric or cloth with gravity. That means the distance or object would be compressed to small scale(black hole).That Time Einstein could not prove that space could be bend due to high technological requirements.

How LIGO measured the gravitational waves?

The Gravitational waves stretches only space at atomic level, that means high level of accuracy of instruments are required to measure it. The LIGO use high power lasers with L -shaped mirrors arrangement. This arrangement used to transfer specific type of photon's wavelength. If condition is normal the two lasers overlap eachother.

It is same like when you make a wave in swimming pool( water ) ,They comes as the same height as it was after meshing at wall of swimming pool. But the disturbance like you come in between the wall and source , the wavelength of water is changed.

Few days ago LIGO found a Gravitational wave. Which generates the stretches of 1/100000 of nanometer. Which is observed for 0.25 seconds. The difference between two wavelength is 0.007 seconds.

That means we have stretched and compressed with 0.000000025 of your hair's diameter.

But how its make Scientist so excited.

This research would tell about the unknown dark universe which is unknown to us. That we can not view or interact. It opens the new way of finding the dark matter which can even pass through us.

It opens the way of finding the new more dimensions.

It would be a first step of making the anti-gravity aircrafts or UFOs.

This research would open new doors to the black hole research.

This research would tell people about how the particle behaves at extreme gravity.

Therefore we can say that it is first step in making of UFOs and understanding our universe.
