Slashdot Mirror


There's a Hole in the Middle of It All

Apparition writes "CNN is reporting that the star at the center of our galaxy is actually a super-massive black hole. The article then claims that it occupies a volume of space about 3 times that of our solar system. If my math is correct, about 230 million suns could fit into that same volume, so it doesn't impress me that the claimed mass of the black hole is only between 2.6 and 3.7 million times that of the sun. So what is up here? Since when do black holes occupy so much space (I thought they were points)? And how can something with a density only 1/100 of our Sun be called super-massive?" I think the article is talking about a maximum possible size of the object, due to limitations on the resolution of our instruments. Nature has a no-registration story about the research. Update: 10/16 23:44 GMT by M : There's an article with more information on space.com, and a press release from the European Southern Observatory.

    The article then claims that it occupies a volume of space about 3 times that of our solar system.

    This might be a misinterpretation. In the ESO press release they say:

    ...the star approached the central Black Hole to within 17 light-hours - only three times the distance between the Sun and planet Pluto.

    So that puts an upper limit on the scale of the thing, but doesn't imply it takes up all of that space.

    That's why we should throw a party at the event horizon. Everyone arrives at the same time and the party lasts forever.

    That or nobody ever gets there and the ride is extremely short.

    I can't remember which was the inside observer and which was the outside observer. I think it mixes reference points. The same time reference point is short, and the never arrive takes forever.

    "Gib Gnab" is actually a phrase from the Hitchhiker's Guide to the Galaxy by the late Douglas Adams.
