It's All Relativity

It's 35 degrees outside and that's being kind. On days like this you wish your entire city was built underground - I envision everyone having a basement with a door that leads to tunnels to get you where you need to go. Even the weak sunlight is depressing. Artificial lighting seems less oppressive under these conditions. I envy bears who hibernate during these months. This seems impossible:

It's in Beirut, if you're wondering.
One day I found myself on that beach, far away from the United States and the baseball season. I'm not sure that an ocean isn't the same as four months as far as separation goes. Space and time are kind of the same thing, if you know anything about space and time. Physicists have actually combined the terms to form "spacetime" as a singular concept. Well, if not a concept, at least a relationship, sort of like a marriage, as space exists in three dimensions and time is a fourth dimension. In terms of relativity, time can't be separated from the three dimensions of space, because "the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of gravitational fields, which can slow the passage of time."

I wonder what a baseball game would be like on the moon. It only has 1/6th of Earth's gravity, so does that mean you can hit it six times further? Maybe if you made the baseball six times heavier you could simulate an Earth game? You probably couldn't throw anything but straight fastballs. The real fun would be trying to field the ball. Ha! And just think, the fastest runner would probably run like Prince Fielder.

And how long would that game take. If gravitational fields slow the passage of time, does that mean you're gonna play a baseball game that is six times as long as an Earth game? Will it take you an average of 18 hours to finish? How long would a game pitched by Clay Buchholz or C.C. Sabathia take? A year?

Baseball on the moon. What a concept.
