Th...Eric, centrifugal force keeps it from falling. Throwing it toward Earth would do nothing; it's still in orbit at the same speed. So it'll stay in orbit. And that same Godzilla is on our TV set at this very second. He's so dreamy!<BR/><BR/>Thanks for stopping by, D. The bullet is indeed very cool. And the game was quite a bit more exciting than the first pitch, I'm guessing.<BR/><BR/>Vicky G, I love the Geia theory. Not sure I believe it, but like many things, it's fun to think about. And you're right about the baseball burning up in orbit. But the baseball wouldn't leave its orbit unless it slows down, and throwing it toward Earth wouldn't slow it. It'd eventually slow due to friction with the air (which is what decays the orbits of satelites), but that'd take a long time. I'm sticking to my guns: even with a heat shield, you can't throw a baseball to earth from space.Clowncarhttps://www.blogger.com/profile/02219213001049223673noreply@blogger.comtag:blogger.com,1999:blog-8947514984021363360.post-65296334542560537672008-04-17T14:15:00.000-06:002008-04-17T14:15:00.000-06:00Well I'm in high school physics and the answer is:...Well I'm in high school physics and the answer is: yes, the ball would, theoretically, hit earth. Gravity though small, exists in space, and this is why satellites and the International Space Station for that matter just readjust their decaying orbits, else they would tumble back to earth, thus, without a doubt the baseball would head to earth almost regardless of how minor the force applied to it was, but here is the catch. <BR/><BR/>It would completely disintegrate in the atmosphere during reentry. Did anyone else see Apollo 13? That space capsule survived only because of the immense shielding; the same concept has been applied to the space shuttle, and unless the baseball was shielded, it would not reach earth at all.<BR/><BR/>Unless a shield was designed to protect the baseball with a duration equal to the amount of time it would take for the baseball to pass into the lower atmosphere <I>and</I> be of a much lower velocity, thus allowing the baseball to be protected during reentry but not be surrounded by a large steel shell when it lands at the baseball field. <BR/><BR/>But then there is the issue of aiming it. The Apollo capsules were landed in the ocean because such falling objects have a very wide area of landing possibilities. The only reason space shuttles can land at predetermined sites is because they have the ability to guide their landing with glider like qualities once in the lower atmosphere.<BR/><BR/>Therefore I have come to the conclusion that your assessment is correct. “I assume he lobbed a throw inside the space station(without it leaving the oxygen interior of the station), it got shown on the jumbo-tron at Yankee stadium, the umpire said ‘play ball,’ life goes on.”<BR/><BR/>That was strange. I’ve never been any good at physics. Besides, my physics teacher is more interested in environmental science; we’ve had an ongoing discussion of the Geia theory, or living earth theory, which proposes that the earth is in fact a living organism, and in the same way a single cell as parts within it that allow it to function, plants and animals (including humans) are a part of the living organism, Geia. <BR/><BR/>Well, I’ll be off to look at the “Daisy Experiments,” possible proof of the Geia theory.Wizardryhttps://www.blogger.com/profile/10180287388143837392noreply@blogger.comtag:blogger.com,1999:blog-8947514984021363360.post-37806071358140867122008-04-17T13:24:00.000-06:002008-04-17T13:24:00.000-06:00love the image of the bullet.I didn't even hear ab...love the image of the bullet.<BR/><BR/>I didn't even hear about the first pitch being thrown from space and I was watching the game!

What little relative momentum is generated by the throw is not canceled by the roughly perpendicular movement of orbit. Even the space station would continue moving, wouldn't it? Just at a rate that we can consider nil.<BR/><BR/>This is all high school physics, though. I could be very, very wrong.<BR/><BR/>Also, I had that same Godzilla as a child. I love how half of them seem to be cackling with glee at the coming raid on Tokyo.Eric Shonkwilerhttps://www.blogger.com/profile/14037998216225336724noreply@blogger.com
