I can think of much “useful science” that could have been prompted by such a observation if it had actually happened. Scientists would have collected data indicating size, mass, speed, and location of the teapot. They would have researched possible scenarios by which a human-manufactured object (not just teapots) could have possibly reached escape velocity from the earth. (Here’s my favorite theory: I recall reading about YECs who believe that one of the ways in which the animals on Noah’s ark were returned to their home continents was being propelled through the atmosphere by volcanic explosions. Perhaps one such explosion was a bit too powerful and some other items from the ark happened to make it all the way into outer space. OK, I’ll admit that not all Young Earth Creationists have a good grasp of g-forces and the survival prospects of things like small mammals and teapots. And I’m obviously not saying that all of my YEC friends and former associates believe this “volcano hypothesis.” But I can’t help but be fascinated by this way of thinking whenever I read about it online.)
Postscript: Hmmm. If scientists had observed pairs of dinosaurs in the same solar orbit as the teapot, that might have added credence to the “volcanic propulsion of Noah’s ark animals” theory.
I really should get back to my work projects before I get too distracted by these recollections.
