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!

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!

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.
