Quote: I just found out that the sound barrier was broken over 100 years ago!
Can you guess how?
Gonna guess firearms of some sort.
Quote:Did the earth lose a corresponding amount of energy from somewhere in this process
Yes, but it was a really, really, superfantastically tiny amount. If you were to slingshot a billion space probes around the earth ever year for a billion years, the energy loss might be noticeable. (Interesting side note - if you drop a book on the floor, not only does the book fall, but the entire Earth lurches up to meet it. Again, a very, really little bit.)
Quote:Do electrons in atoms in space ever stop moving? What about at absolute zero?
No and no, because absolute zero is a theoretical limit that can't be reached. This isn't a matter of engineering, it appears to be built into the fabric of the universe.
Quote:If so, can we then "know" exactly where the "frozen" electrons are
If so, then yes. Since the Uncertainty (hate that term) Principle regards two properties, position and motion - take away one and you can find the other. Mind you, if electron motion, including the quantum jumps, were eliminated, things are likely to get very nasty before you have time to make your observation.
Quote:If not, and the then if the electrons are still moving according to the uncertainty principle, even at absolute zero, then where do they get the energy to do this.
It's called 'zero point energy'. Lots of good articles about it online.
