    New study about the rise in global sea levels

    He who evokes Star Trek in a serious discussion loses. But... This discussion smells exactly like ONE Vulcan displaying "intellectual superiority" before a LARGE group of "irrational humans". Not in 'real life', but on TV. FICTIONAL. And not because it makes sense, but in order to illustrate...

    B Dwarf Planet or Stellar Moon?

    It's a stupid question with a stupid answer. The dictionary seems not to know what a moon is. Thus, the question, and the argument.

    B Milky Way is "in the top percentile of all the galaxies that exist"

    A Dunning-Kruger demonstration? Allow me to proceed. The interesting thing is we have a fairly good view of one galaxy, and are making sweeping claims about all the others, many of which are permanently out of sight. The other interesting thing is, the word Galaxy might arguably include these...

    I Guarding Mars' atmosphere with a magnetic shield

    Seems temporary. And vulnerable to a missile, if someone lacks patience. How much trouble in tossing a phone pole sized bar magnet very precisely (smart bomb) at the Poles of the Planet? How many would it take to magnetize the planet? Would't really matter where you set up the factory. Robots...

    B Are black holes perfect spheres?

    I'll go check. I'll let you know what I find out.

    Why colonize Mars and not the Moon?

    Strike that word 'potential'. We are fairly clever apes. We just might invent something.

    Why colonize Mars and not the Moon?

    Air. Mars has some, the Moon has none. If you are going to try to make something, it's good to have something to work with. Where would Dillinger be without that bar of soap?

    Could a ballistic missile be used to deliver cargo?

    It would be better to use a phone to ask someone already there to deliver one of whatever the heck is so damn important. Trying to think what it might be. FAIL.

    Could fracking technology be used to raise land threatened with water inundation

    But there are no peer reviewed scientific references regarding using fracking to raise land.

    How is it possible that friction = centripetal force for turns?

    Well then. You better forget everything I said.

    How is it possible that friction = centripetal force for turns?

    Travis. A.T. Please pick up a bowling ball. Hold it at arms length, head high. Now, rest. Does it not upon due examination turn out that YOU, yes YOU, were holding the ball up? And what happened to the ball? Did it not achieve of it's own volition the lowest potential energy state available...

    How is it possible that friction = centripetal force for turns?

    Not at all. A car on a hill will roll down the hill. It is the brake, acting continuously, that prevents the car from rolling. A magnet stuck to a fridge would, if not for the magnetic force, fall to the floor. In both cases friction, STATIC friction... acts continuously to prevent...

    How is it possible that friction = centripetal force for turns?

    A magnet stuck to a fridge is not at rest. It's just stuck. A car parked on an incline is not at rest. It's just parked. I specifically mentioned that. And to emphasize, Friction is the force that Resists relative motion between objects in contact. It can do so successfully. When that...

    Speed of massless objects

    Yes. Exactly. Photon emits. Photon strikes object. No time in between. Again, I concur. At C, time stops. However, at the time of the thought experiment, Einstein could not know that, because he hadn't discovered it yet. This led him into error. In discovering and correcting that error, he...
