    Two supermassive black holes reeeeeeealy close to each other in Andromeda.

    If anyone has a more sciencey source I would like to read that instead. I wonder how they identified separate SMBH signatures to near each other. I wonder what the merger would look like to the LIGO detectors.

    If something were travelling faster than the speed of light, could it escape a black hole?

    Dunno, but let me know when you spot that "something".

    Well, you know, it's the old Groucho quote "If we had some eggs, we could have ham and eggs, if we had some ham"...

    So there could be super-luminal stuff whizzing out of black holes and the only way we’d ever know about it would be...?

  1.  
    There could be transsexual unicorns whizzing out of there too.
    Or Not.

    That article is misleading. It's clear from the abstract of the paper that the black holes are at z=0.231, so they are background objects shining through the Andromeda galaxy, (which has a small blueshift). And they're a long way away from here.

    Was there a link to a paper that I missed? Would you be willing to post it?
