Study of astronomy changed by new discovery

First theorised by Einstein a century ago

A local expert says the recent discovery of gravitational waves in space is a major milestone in astronomy.

Scientists have detected clear gravitational waves, or ripples through space, that were first theorised by Albert Einstein a hundred years ago.

The discovery came from the Laser Interferometer Gravitational-Wave Observatory (Ligo).

Howard Parkin of AstroManx says it will change the face of astronomy.
