    A filmmaker wanted to depict a realistic view of a black hole, so they consulted with a physicist, who wrote up some algorithms to depict gravitational lensing for CGI work. The result came out looking like this:


    The extreme lensing effect makes it look like the glowing accretion disk wraps over and under the thing, when it is actually just a flat ring around an ecliptic (orbital plane) not unlike the rings of Saturn.

    Freaky. Keep those things away from me.

    No, nor are any Bejorans involved, it is about black holes, not wormholes.

    Coolness, indeed. Thanks for posting this.

    NASA has had an artist's (2D) concept of a supermassive black hole up for a while, that makes for rather nice desktop wallpaper, that's available in a variety of resolutions (thumbnail below.)

    I'll see it but Matthew McConaughey is really miscast for this Bruce Willis-type action movie. He's much better suited for "films" like Mud and Dallas Buyers Club.

    I am very excited to see this movie. They just build a Cinemark XD Theater close to my house, and this is going to be awesome there!!!

    Black holes don't exist any more, or at least according to their main exponent, the great, severely-disabled staunch atheist Stephen Hawking.

    As Homer Simpson said, when being sucked into a black hole, "I should've listened to that wheel chair guy!"

    Yes, they most certainly do. The recent "controversy" was a particular aspect of black holes, their ability to radiate energy, that caused the problem. Termed, "Hawking radiation", it basically described the ability of quantum fluctuations triggering the spontaneous formation of entangled particles at the event horizon. One of the particles forms within the event horizon, and is of course lost for eternity within the confines of it. However, the other one could theoretically escape, and would be able to "radiate" away from the black hole. This would result in eventual "cooling" of the black hole. Mr. Hawking had an epiphany and doubted his previous work, but his work has been rigorously verified as sound by his contemporaries.

    Black holes still exist, just like the entirety of the real universe. It all exists whether you believe it or not.

    Lastly, your "description" of Mr. Hawking is . . . odd . . . , if not somewhat offensive.

    Read this article, he wasn't staying they don't exist
    [MOD NOTE]
    Also lets avoid any PRSI type discussion regarding what Hawkings being an atheist. That will certainly derail the thread and is not germane to the topic.

    The logical problem with black holes is the extremity of time dilation involved in the collapse. To us, the outside observer, we "see" an event horizon, but since the warp of spacetime effectively stops time for us, the outside observer, at that boundary, for all we know, the collapse is currently an ongoing process that will never form a singularity within the timeframe of the lifetime of the universe.

    In other words, the math that says that black holes will not actually form is kind of irrelevant, because, in practical terms, for us, they do form, just probably not in exactly the way as has been depicted. We never see formed black holes, we see black holes forming, but the difference, for us is vanishing. So to speak.

    Can't wait to see this movie in IMAX. I'm sure my wife will fall asleep in the theatre though. :rolleyes:

    Not necessarily, just calling a spade a spade. Nothing wrong with that, I don't think. Anyway, from a karma point-of-view the two highlighted aspects go hand-in-hand. :)

    I respectfully disagree. McConaughey brings the fidelity that this role demanded that Bruce Willis lacks. His forte is over the top action like Armageddon.

    My comments were based on a few pre-release commercials. Now that it's released it appears not to be the movie I was expecting. I look forward to seeing it.

    Seriously? I mean, I am no fan of Bruce Willis, but the man definitely has range. Have you seen Nobody's Fool? Or that Vonnegut thing, Breakfast of Champions? Now, if you had said Costner or Ford, I might agree, but Willis, that lump could have pulled it off np.

    Bruce Willis in space? Armageddon or The Fifth Element instantly pops into my mind, over the top, kick ass, but very enjoyable. :) He would have been miscast in this role. :)
