Guest Suzz Posted March 6, 2004 Share Posted March 6, 2004 I'm not really sure if this belongs here but oh well, here goes: I read that perfect vacuums are impossible even with the best equipment. Can someone here please answer if this is true, and why. Thanks! Link to comment Share on other sites More sharing options...
aommaster Posted March 6, 2004 Share Posted March 6, 2004 Yup! True! To make a perfect vacuum, you must have absolutely NO matter or any subatomic particles in a space. To make something like that is impossible, cause no matter how hard you try, there will yet be a little bit of air or some matter in it. Also, actually containing it is impossible. Glass doesn't work! Its impossible. Even space isn't a perfect vacuum! Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted March 6, 2004 Share Posted March 6, 2004 See, if you make a container out of glass or whatever, glass molecules will break off and prevent it from being a real vaccuum, and of course it's hard enough without a perfect vaccuum pump.

fafalone Posted March 6, 2004 Share Posted March 6, 2004 Well in principle it's possible for a small amount of time. If some sort of ultradense shield was invented that was capable of shielding the small massive particles like neutrinos, then a perfect vacuum could exist for a short time. Only a short time because particles continually are created and destroyed due to vacuum flucuations. Link to comment Share on other sites More sharing options...

Cap'n Refsmmat Posted March 6, 2004 Share Posted March 6, 2004 Or create some kind of magnetic field that keeps all particles out. Link to comment Share on other sites More sharing options...
