I know (I'm a computer geek).. but how's that relevant to the question ?.. except for the fact that it's a near-perfect plane that could enforce my question.
I know the question sounds a little bit noobish but If you place a CD on a clean glass table seems like the CD is floating. There's vacuum between the CD and the glass stopping you from picking it up yet the CD seems to be floating.
If not I would like to know what other forces could be acting...
