    Does this make sense..... nothingness does not exist? At least within our universe.


    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    From the article:

    Researchers are now comfortable with the fact that empty space isn't empty at all - it's actually full of quantum fluctuations that we're only just now learning how to detect. But we're still struggling to find tools sensitive enough to measure these tiny forces at play.

    There is no space between the fluctuations? Does that mean it is all one interconnected fluctuation?

    Is it a field that is fluctuating and does it perhaps fluctuate between negative and positive values where we "live in" the positive** values? (not intended to sound new agey ,I just meant mathematically/physically)

    Am I anywhere near at all what they are talking about?

    **anything intrisically different between negative and positive values?

    Read the article. I have nothing to add - I am a mathematician, not a physicist.

But there cannot be a relative velocity between an object and quantum fluctuations because this would violate Lorentz invariance.
    There are no paradoxes in relativity, just people's misunderstandings of it.
