Now that we've landed and I've actually had time to watch this.
Great video, thanks for the link.
I think this definitely does answer some of my speculation, namely being that there isn't much in the way of empty space. However, this still begs the question, where there are more and less densely filled space (i.e. the center of a brick of gold versus the intentionally sealed vacuum of a thermos), are the almost incalculable voids between fluctuations more or less numerous? I also like how he addressed the increased energy requirement to make a true [albeit unstable] vacuum. This is something I remember discussing a while ago, where it can be said that nothing sucks, but everything blows. Plainly, that sources with higher energy/ pressure/ density will constantly be trying to fill areas with less. And in order to keep those areas that are less full of stuff empty, it takes massive amounts of energy- i.e. levees.
Also, I think this also supposes that I didn't really express my intention clearly.
What I'm really talking about is space, as in the location. If you were to think of the whole universe as existing on a multi dimensional coordinate system, everything (all quarks, fluctuations or kittens considered) would exist at some set point within that system. However, the objects would be constantly moving.
For example, I place my computer on a table. In relation to me, and hopefully the table, it stays in one place. However, in relation to the sun it is rotating on a given axis and around a set orbit. Further, in relation to the center of the galaxy, it is rotating yet around the center of the galaxy also. On of my questions is, are there set coordinates within space, and objects are simply moving through these coordinates. In other words, are we moving through set space?
