I mean all space is a vacuum but cannot be a perfect vacuum because at the end of the day, if it is inhibited by nothing but space, then it is still inhibited by space: So therefore either a perfect vacuum cannot ever truely exist or such a thing does exist but since it is not reletive to space or time we shall never observe it because technically, it would not exist: Can anyone make sense of this?I mean in the sense of absoloutely no fluctuations, and no space or time to inhibit such a realm: Im asking could you observe this at a physical point of view or is it the sort of thing which we knew existed but could never prove due to technological restirctions(Other examples of this is the centre of the universe idea). An a cannonical vacuum is still inhibited by particles of some form or another, and will definately be contaminated with either dark energy or neutrino particles.14 minutes ago

Answer Question

by Don M Member since:June 13, 2006Total points:21,810 (Level 6)Are you talking about a canonical vacuum, that is, one without so-called quantum fluctuations? I suppose theoretically you could... that would be basically a zero-energy Higgs field as I understand it. But you would not be able to confine the vacuum without creating energy, because doing so makes the position of the vacuum less uncertain, and thus increases the energy.
