  1. To Be Fair... on SpaceX Falcon 9 Relatively Cheap Compared To NASA's New Pad · · Score: 2, Informative

    SpaceX's main cost-cut compared to NASA is they're building it for themselves, by themselves. NASA doesn't build any spacecraft, they hire contractors. They have to pay their own people to operate the project plus the contractors to make the vehicle.

    To be honest as well as fair, this is where things should expand into the BigAero Sucking NASA'a Corporate Welfare Teat Dry, but everybody knows that one already and the punchline sucks. Or used to. Looks like the new punchline just might be 'SpaceX', which, to quote Spock, "thrills me no end."

    The difference between Paul Kantner's Hugo nominated album (and soon to be Broadway musical) and TFA is that despite having equal veracity as predictive statements, the former was intended to be taken as a work of fiction.

    I wish someone would start collecting such futurisms and create an award ceremony a la Ignobel Prize, to honor them when time punctures their balloon. They could sell tickets and use the proceeds to buy a flying car to give away as a door prize. I'm betting they could actually do that before desktops (READ: floor sitting equipment boxes that keep the desk clear) disappear.

  3. I Call BS on Italian MEP Wants To Eliminate Anonymity On the Internet · · Score: 1

    Otherwise, let it begin here. Let's see everything made public that is sent or received by any member or associate of Italian government, public or private, and then propose the same for every Italian citizen. Italians relate to their government like fans at a football game, so if t5his made the first level and the second got proposed, figure the odds on the offending blowhard still being in office in order to bring it to a vote, even the next day.

  7. Donut Holes on How To Destroy a Black Hole · · Score: 1

    I want credit for the name if the maths work out.

    Consider the Kerr solution, a rotating, non-charged body approaching the Schwarzchild limit. As it shrinks the spin increases. As this happens the matter near the edge of the now disk-like body gains mass via increased speed a la relativity. The amount gained may not be significant in normal space, but near the Schwarzchild limit it might prove enough to alter the development of the hole. (This mass gain may or may not serve to increase rotational speed more. If it does the following becomes more likely. We'll take the conservative view and ignore this possibility.)

    As the body as a whole nears the limit, any portion of the body with greater mass will cross the limit first. This is generally taken as the center. However, the additional mass of the material near the edge of the disk causes it to cross over first and development of the hole begins around this material rather than the center. The hole begins to develop as a toroid. The matter that crosses over first becomes a singularity in terms of its effects, but takes the shape of a ring. The resulting toroidal black hole finishes its parent body off as the outer portion having turned into a black hole pulls in the remaining matter nearer the center, feeding the toroid formation process. The result is a black 'donut' hole, with a path through the axis that does not cross the event horizon. The center is empty (ie. non-horizon involved) because of the balance of gravity in the region neat the 'center' where the gravity from the opposite side of the ring balance out. The size of the hole remains to be calculated. From macro to quantum sized as long it stays non- zero, the donut remains. Even zero may work out as a toroid with a zero diameter center is possible. Perhaps only a negative result (indicating a merger of the opposing event horizons) ruins this postulation.

    The singularity ring itself is presaged in description by Mbrane theory. It is simply a circular macro-string of the sort postulated as having been created with the Big Bang. One could approach this from the other direction and starting with that description increase the mass until an external event horizon forms.

    The above approaches the Kerr solution in tiny steps very near the time of formation and the logic as well as the physics and associated maths well known. It shouldn't be too difficult to test. If it is borne out, the paper referred to in the article, regarding 'destroying' a black hole, may have other solutions to consider. While an increase in angular momentum may 'destroy' a particular conformation, rather than shedding the event horizon, the singularity/hole may simply take up another form such a what is described here. If a rapidly spinning object can form a toroidal black hole, perhaps a rapidly spun black hole can also.

    1. There is no such thing as "perfect" vision. There is normal vision that requires no correction. Typically that comes down to 20/20 vision. There are some people with better vision. Very good eyes are measured as 20/10. There is no limit, physiological or theoretical, hence no "perfect".

    2. Resolving things at any distance requires far more than static placement of object with X size and retina of Y resolving power. The visual system (NOTE the retina does not resolve ANYTHING. The visual system as a whole does.) resolves things by a complex interplay between what's presented at any given point in time, what's presented at other times but is cognitively determined to be the same target, the speed at which the boundaries of images cross the same point in the visual field, and calculations that occur in the visual cortex on these things, which result in a VISUAL ACUITY (that's the term they were addressing, or should have been) that is often far greater than can be conceived of when one considers the components of the eye as though they were parts of a camera or other device.

    If the suggested theory (using the term at its loosest possible fitting) is correct, it would have been noticed not long after "Watson, come here, I need you." It wasn't.

    What people found most annoying at first, and some still do, is the violation of accepted protocol of interpersonal communication. When someone near you starts to talk out loud, it had always been a safe bet that they were talking to you. You redirect your attention and prepare to interact. Then you find out they weren't talking to you, may not even be aware of your existence, but there you are standing in front of them feeling like you've been made a fool of (or made of fool of yourself by starting to talk back). And It's All Their Fault. After a decade and more of experiencing it, fewer are bothered, and half a generation has been raised on a different context and can't understand why there was even a problem.

    Another effect comes from violation of personal space (there's an auditory version as well as a visual-spatial). If someone invades your space without acknowledging you so they can apologize or get permission or whatever, it's a nonverbal communication version of a slap in the face. And as for failing to acknowledge you, when someone fails to consider whether you want to hear whatever it is they're blabbering about and fills your hearing space with talking far louder than is needed (especially considering they're not talking to anyone in sight), they're making an implied statement that if it bothers you, too fucking bad for you.

    There are even some people who make a point of talking louder than they would otherwise because they want you to know they think they're important and you're not. At first, when only the rich could afford them, they made a point of doing this in restaurants and other places, even repeatedly interrupting a conversation with you or someone else to 'take a call'. There were more than a few comedy acts and sitcoms that jabbed at those people by emphasizing the few but true instances of people faking calls to do this in others' presence. The same happens now, but more often with people who couldn't afford to keep their phone on but don't want you to know that.

    A one-liner version of this all could be "look at me not talking to you".

    But as I said, with the passing years most people who were bothered have gotten used to it, and many more have come of age around it and have never been bothered.

    Then again there are those few, those oh so unhappy few, who have not and will probably never get used to it and will always be bothered.

But rather than just interference, it'll turn on a tesla coil and broadcast thousands of volts through that little piece of hellspawn technology frying the little shitbox as well as blowing their inner ear through their brain and out the other ear hole, and then we can jump up and say "LET'S SEE YOU SAY 'WHAT'S UP' WHILE LOOKING AT ME BUT THEN WHEN I START TO ANSWER YOU IT TURNS OUT YOU'RE NOT TALKING TO ME, NOW, YOU FUCKING BRAIN DEAD FREAK!"

Most of his negatives could be applied to movies, and many of them are a matter of opinion and/or taste.

    In any case, Ebert is a "critic", meaning he can't do what he talks about, he can only be critical. Not only can he not create a computer game, he can't make a movie either. So why do people pay attention to him? Because he is, as are almost all "critics" an entertainer, and we have been trained by the media to accept their designated authorities as experts based on their entertainment value. Now, he is quite knowledgeable about the history and such surrounding film, but the fact remains he only knows stuff, and makes a show of knowing it, yet cannot do.
