Double trouble! Two pairs of giant black holes spotted on collision course

[Admin]

Two pairs of giant black holes set to collide have been spotted by NASA's Chandra X-ray Observatory, the first evidence of such a cosmic collision.

So, at 760 million light-years from Earth, would the gravitational waves from the closer merger be detectable by LIGO?

BRILLIANT Question! I was wondering the same thing.
OTOH, I thought, if we can detect it optically and with X-rays, shouldn't we be able to...?
OTOH, what ARE gravitational waves made of?
OTOH, gravitational waves made an acousitc signal last time.
OTOH, whew! I'm out of hands.
Still, absolutely BRILLIANT Question!!!

What kind of time-frame are we looking at for the collision to occur?
