Subject: Matter in a vacuum
I was discussing with some other educator-types whether there
is ever a true friction/air-resistance free environment; someone
said a vacuum, and I said even in an alleged vacuum matter actually
appears and disappears. I can't remember where I heard or read
about this but it might have been at the Exploratorium ... and I
seem to remember it has something to do with the Heisenburg uncertainty
principle, that energy can be created or destroyed but only within
a certain time limit. Can anyone comment on whether or not this is true?
Thanks!
