Final Question from A.Einstein.

ICRR Gravitational Wave Project Office (GWPO) is challenging the direct detection of gravitational waves that have not ever been detected in human history. The gravitational waves were ripples of space-time that were predicted by the general theory of relativity of A. Einstein. Many projects in the world are also trying the direct detection of gravitational waves, competitively and collaboratively. Why do we and many projects try to directly detect GWs ?

Light and Gravity

In the Universe, light and gravity are the most fundamental method to send information far away. In the previous human history, we obtained much information of the Universe only by electrical magnetic waves whose origins are charged. If we can detect gravitational waves whose origins are masses (gravity), we expect that completely different aspect of the Universe can be exposed.

See the history of the Universe that cannot be detected by electrical-magnetic waves.

We cannot see 40,0000 year history of the Universe after the big bang, because the temperature of the universe is too hot for EM waves to propagate without scattering. However, we can see it with gravitational waves because GWs have so weak interaction that can transmit everything.

Catch the scoops of big events in the Universe by GWs !

GWs are firstly emitted from big events in the Universe, such as Supernovae, Black holes generation, Gammer Ray bursts and so on, and are estimated to travel at the speed of light that is the fastest speed in the Universe. So, the first information about them can be obtained by GWs.

Poor research results about Gravity.

The understandings about gravity are much less that those about other physical fields such as quantum mechanics because the strength of the force of gravity is extremely weaker that that of the elactro-magnetic force, the strong force and the weak force that dominates the quantum mechanics. Gravitational waves are emitted from astronomical phenomena where the gravity force becomes extremely strong. So, the detection of GWs can be a good chance to explore the property of gravity.
