Gravitational waves detection

An interesting results : gravitational waves measurement for the first time !

The collision of two black holes allowed gravitational waves detection. This important result confirms the material nature of Einstein spacetime as a continuum media. Moreover, it confirms that spacetime has physical properties, i.e. a density and a viscosity.

No at this time I have not informations about waves characteristics. But I can be quite sure that the information is true.
My personal explanation of the detection is we needed an extremely violent event to detect something because spacetime could have a very high viscosity able to avoid waves propagation. Tidal forces or orbital changes are too mild events to cause a wave propagation even if they are closer.

Thanks

Yes Axil, I agree with you.
