Two notes for readers

September 26, 2022 • 3:06 pm

1).  If you’re a first-time poster, read “Da Roolz” on the left sidebar, or here. They give useful hints for commenting on this site. Entirely too many comments lately have uncivil or rude, and many of them you won’t see. It’s okay to disagree, but pretend you’re having a drink in the living room with the person you’re disagreeing with. This includes me.  Obtuseness, arrogance, and untruths asserted as truths may also be binned. If you’re a creationist, you’re on shaky ground!

2.) Be sure to watch the DART spacecraft try to hit the asteroid tonight. The collision is supposed to occur at 7:14 EDT as recounted here. Don’t miss it! The link has a YouTube site where you can watch the action live (well, 45 seconds after it happens/does not happen.)

    [ tries to write comment with drunk person at bar voice, grammar, gesticulation, and language
    [ erases comment ]
    [ hopes someone knows what that is ]

    1. I define “obtuse” as making the same point over and over again in an obstreperous and annoying way, most often disruptive when the point is RONG. I issue warnings to knock it off before I’ll ban anyone.

  2. On the collision with the asteroid: Aren’t we pretty sure already that Newton’s Laws will prevail and the change caused by hitting one of the asteroids will be just what we calculate it should be? It seems a little odd to me to be saying we are “seeing if it will work” and we have to “find out what it did.”

    1. I think that the degree to which it’s gravelly makes the behavior/quantity of the ejecta slightly unpredictable. IOW, it’s not a perfect billiard ball.
