This must have hit the media world-wide recently
http://www.bbc.co.uk/news/science-environment-35524440But I would like to know, if you can help me, what the difference is between the subject and gravity waves (I suspect you have to search ‘gravity waves’ from this home page)
http://rapidfire.sci.gsfc.nasa.gov/cgi-bin/imagery/gallery.cgiN.B. There are cloud vortices and cloud streets too from NASA.
P.S. The current BBC Reith Lectures are on black holes – what did they know?

Cloud formations described as gravity waves are completely different things from the gravitational waves that Einstein predicted. The clouds are formed by mechanical waves that are periodic movements of the air propelled by the restoring force of gravity. Ocean waves are also gravity waves. Gravitational waves are waves in the space-time continuum – i.e. waves in the very fabric of space.
Bizarrely, I once had dinner at Professor Stephen Hawking’s house in Cambridge to interview Professor Kip Thorne, the world authority on gravitational waves. This was for the waves book I wrote back in 2010. It is amazing that they have now finally been discovered.-
Just stumbled on this Cambridge view of the Einstein waves

Iris ter Schiphorst ‘Gravitational Waves’
I think it may have been CAS Forum stalwart Andrew Kirk, a trained singer, who often related cloudspotting and music. So herewith music inspired by gravitational waves of the Einstein sort
