Submission + - White Dwarfs gravitational waves found (bbc.co.uk) 2

Dupple writes: Researchers have spotted visible-light evidence for one of astronomy's most elusive targets — gravitational waves — in the orbit of a pair of dead stars.

Until now, these ripples in space-time, first predicted by Einstein, have only been inferred from radio-wave sources.

But a change in the orbits of two white dwarf stars orbiting one another 3,000 light-years away is further proof of the waves that can literally be seen.

    It's not really though, is it? That's a bit like claiming that you've literally seen the curvature of spacetime because you saw an apple fall from a tree.

    • Never mind, I'll jump in before some other smart arse does! It's the proof that you can literally see, fair enough. I'll get me coat.
