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.

We will have solar energy as soon as the utility companies solve one technical problem -- how to run a sunbeam through a meter.
