First, my apologies if this topic is in the wrong section but since I don't know anything about physics and I sometimes wiki stuff, I have some sort of very amateur knowledge on that subject. Anyway, Stargate SC-1 and Atlantis are the TV shows which got me interested in all the technotalk, and I've been eally intrigued with the 'ZPM'. Basically, I'm all sci-fi, but I always feel compelled to make my stories as realistic as possible, thus my presence in these forums. So my question is: How does the ZPM work? Wikipedia description says: it extracts zero-point energy through artificially-created subspaces... So I didn't quite understand what zero-point energy is. It's described as ground-state, lowest possible energy... it's very confusing. And does zero-point have a relation to Quantum Foam? (btw, is Quantum Foam related to the ZPM?) Please, can anyone clear that up for me? All the technotalk is enough to scramble up my brain, and please, do not use any equations or jargons! This inquiry frm my part is because I'm looking to see if a power-source concerning subspace or something similar can be theoretically viable.
