Is there anything you can do about the fact that the moon has 1/6th Earth gravity when say a hundred years or two from now, you have cities on the moon and you want to play basketball or tennis or baseball. What would the courts look like? How would the games differ from Earthy versions? Like in tennis, you whack the ball and it won't be curved back to the ground like on Earth, not nearly as much curvature but you can hit it just as hard so the shots will be more straight lines. How will that change the game? And the same question about basketball, ballistic curves will be a lot shallower so to get a basket, how would the players have to adjust? Wouldn't it mean, for instance, that a pro team coming from Earth could play an amateur team on the moon and not overwhelm the amateurs? Shooting the balls way to hard and so forth, same in tennis.

One idea I have would be to have magnetically responsive balls, light weight of course but huge controlled electromagnets in the sub floor that would cause the balls to have flight trajectories similar to what it would do on Earth, a kind of artificial gravity. Of course it would not effect the players who would be for the most part non-magnetic. Would it even be possible to build such a stadium using powerful electromagnets? One thing for sure, you wouldn't want to take your credit card to the games....

I would suggest one could play squash instead. You'd need to be inside in a bunker anyway to protect against radiation.
