    Toss up : a coworker who I would have counted as quite intelligent said we haven’t been to the moon because “it’s impossible to launch a rocket to the moon and land on it because rockets go in a straight line. Trying to time the shot of the rocket, and get to the moon at the exact moment when the moon gets to the right spot would be astronomically impossible. The odds of pulling that off at the speed you would be traveling and the distance you travel… Well the odds are effectively zero.”

    "Also you can’t catch up to the moon because the moon is traveling faster then our rockets can go "

    Either that or a prochoice individual who voted for Trump…

      How does this person think things like ICBMs work? They just go straight up and away from the earth and can’t turn?

      The first argument is more or less understandable (still wrong): you can’t just propel yourself upwards at your earliest convenience to reach the moon, you have to play around with orbital mechanics.
      If your friend’s idea of a moon-worthy vessel is an unsteerable rocket with infinite fuel and a chair strapped to it… well the odds are effectively zero.

      The second argument? bro, last time I checked the moon was still orbiting Earth

        The friend should play Kerbal Space Program. It will be a fun way to show that yes, it’s really hard, but it is possible to play around with orbital mechanics and get to the moon.

        And then it will show that an unsteerable rocket with infinite fuel and a chair strapped to it is also possible, just really really hard.

          I imagine the latter isn’t too hard, you just have to get it right just before leaving the atmosphere (quick saves help); however, isn’t landing (not crashing nor rolling around) on the Mün without steering straight up impossible?

          Though I can see some rocket landing on a planet with an atmosphere…
