The story is 1.3 billion years ago 2 black holes collided to form one. They released energy equivalent to that of 3 suns , the wave stretch Space time by of 1 x10 power -18 1.3 billion years latter and they have worked out how to detect it. :shock: :shock: :shock: :shock: :shock:


Sorry a physics geek at heart


Don't apologise!

Re the energy release: our (somewhat measly) sun has been belting out energy for 4 or 5 billion years and should go on doing so for roughly the same time. The collision released the equivalent of three times all the energy the sun ever has or ever will emit in a fraction of a second.


would that be 'quite hot'?

Or weather.

Or satellite launches.

Or astronomy.

I work with a guy who's a big conspiracy theory nut. He believes almost everything although I think even he baulked at the idea tha the earth is flat, although he obviously thought about it when I asked him...
He's very funny - aliens (the one's that live amongst us) could take him to mars and show him the mars rover first hand and he'd still believe it's a conspiracy (apparently the pictures it takes are of Canada).

Well the American claim to have put a men on the moon is certainly untrue and not because they faked the landings.

Didn't I mention the Grassy Knoll, upthread?

Could you expand on that a bit?

I'm guessing he's talking about Wernher von Braun (amongst others).

The single most convincing piece of evidence for the moon landings?

I mean other than the stuff they left there (like retro reflectors which we use in measurement labs to this day)....

The Russians never said they didn't do it.

Yep - simple really. It was Germans who put the men on the moon - the yanks just financed it. It all stemmed from something called operation paperclip in which the USA grabbed over a hundred rocket scientists from Germany at the end of the war.

Phew, I was worried you'd been finding Manc33's arguments persuasive.

On that basis the Americans haven't done anything aside from perhaps some stuff done by native Americans. Apple's Syrian, Facebook is Israeli and the country is run by a Kenyan. :wink:

Indeed. Triangulating the simple radio systems they had back then would have been a doddle. Easy to prove they didn't come from the moon if it were true.

But Jobs was born and brought up in the USA as was Zuckerberg - Judaism is a religion not a nationality. You're obviously one of those birthers if you don't think Obama isn't a born and bred American.
