Interesting. You are on a one-man crusade against the Hypothetical. What has a hypothetical ever done to you, force some sort of inactivity on your part?
"Assume your car runs out of gas, tomorrow."
"My car never runs out of gas."
"Uh, ok."
Nope, no crusade here. A hypothetical generally has a valid starting point. I don’t see it in the 0.9c baseball (since it necessitates ‘magic’ - which I don’t particularly believe in). I guess my standard for a hypothetical differs from your’s. So be it.
Have a great day and watch out for those relativistic baseballs! Those can be nasty. My sister once got hit by one. Hypothetically.
