comment What is the Physical Meaning of Commutation of Two Operators?
"The order of your measurements is in general important". I'm not sure how that can be the case. In relativity, the order of measurements may in general depend of the frame of reference.

comment What are the Implications of Bell's Theorem?
...Continued Of course, mere correlation between distant events does not by itself imply action at a distance, but only correlation between the signals reaching the two places. These signals, in the idealized example of Bohm, must be sufficient to determine whether the particles go up or down. For any residual undeterminism could only spoil the perfect correlation." -- John Bell

comment What are the Implications of Bell's Theorem?
@ Johannes. :) Well taken. I'd however recommend you read Bell's papers and articles on the meaning of his theorem. For example: " It is important to note that to the limited degree to which determinism plays a role in the EPR argument, it is not assumed but inferred. What is held sacred is the principle of local causality' -- or no action at a distance'. Continued...

I gave +1. But, I still don't think you get it.

comment Is there always a frame in which spatially separated events are simultaneous?
Just one question, the answer you gave would change if we were to allow information to travel faster than light right?

@Kevin, :) true. Thanks for all the answers.

comment Is there always a frame in which spatially separated events are simultaneous?
OK, but my original question is whether given two events with arbitrary time delay in the rest frame between the two events, and arbitrary separation between the positions of the events, can we then always find a frame in which they are simultaneous? I think the answer you have given is no. This is good, because for example, it's absurd that me typing this message is simultaneous with say George Washington's birth from some frame of reference.

Good answer. Somehow this violates my intuition though. I feel like I see simultaneous events all the time with only a small amount of distance between the two events.

Well, there's no causality in my question at all, which is why I down voted.

In my question body, I specify that the two people dropping the balls are on opposite sides of the tennis court, so they are spatially separated.

@ Mitchison, "It is important to note that to the limited degree to which determinism plays a role in the EPR argument, it is not assumed but inferred. What is held sacred is the principle of local causality' -- or no action at a distance'. Of course, mere correlation between distant events does not by itself imply action at a distance, but only correlation between the signals reaching the two places. These signals, in the idealized example of Bohm, must be sufficient to determine whether the particles go up or down. For any residual undeterminism could only spoil the perfect correlation."
