    And you thought this was about Robin.


    For the first time, scientists have peered to the edge of a colossal black hole and measured the point of no return for matter.
    A black hole has a boundary called an event horizon. Anything that falls within a black hole's event horizon — be it stars, gas, or even light — can never escape.
    "Once objects fall through the event horizon, they're lost forever," Shep Doeleman, assistant director of the MIT Haystack Observatory and research associate at the Smithsonian Astrophysical Observatory, said in a statement Thursday (Sept. 27). "It's an exit door from our universe. You walk through that door, you’re not coming back."
    Although the event horizon is an imaginary line that's impossible to observe, astronomers have imaged the region around a giant black hole at the center of a distant galaxy, and measured, for the first time, the closest stable orbit in which matter can circle the black hole. The findings were reported today in the journal Science.
    The supermassive black hole in question lies at the center of the galaxy M87, which is about 50 million light-years from our own Milky Way. This behemoth black hole contains the mass of 6 billion suns.

    I haven't read it, but based on the OP's post:

    A black hole is just a region of infinite gravity where space, matter, and time cease to have any meaning. Around the center of the black hole, the region of infinite gravity extends outward in a diameter determined by the mass of the black hole, formed when a star larger than about 10 times the mass of our Sun collapses at the end of its life. Smaller stars stop collapsing before forming a black hole and leave a white, brown, or red dwarf, based on their initial mass. There's a distance from the center of a black hole extending in every direction that is a point of no return for any matter that gets that close to the black hole center. Further away from that line, gravity is strong but not infinite and, in theory, something could approach that close and then still get away. That line's called the "event horizon" and once you cross that line, nothing (even light) can escape the black hole because the velocity ("escape velocity") necessary to overcome gravity would be infinite, which is impossible. (On Earth, the escape velocity is about 25,000 MPH, which is how fast rockets have to go to achieve earth orbit. The larger the planet or star, the higher the escape velocity. Black holes vary in their size and mass but wherever their event horizon is, that's where the escape velocity would become infinite.) Apparently, they managed to measure the exact size of the center of a black hole. Capieche?

    Its tells us the mass so whats the measurement?

    The best way to describe a black hole is this: it's a really big thing which doesn't allow gas to escape.

    I wonder why they didn't measure the black hole at the center of our galaxy. This other one (in the other galaxy) was closer? :scratch:

    Ah, never mind my previous question.

    It's always about size with these nerds. :jj:

    although the mass doesn't really mean the size, i.e., the mass of 6 billion suns may only be the size of 100 suns--black holes are incredibly dense.

    So it's not the length; it's the girth? ;)

    That is a lot of Robins! An awful lot even at her peak weight.
