What Is Nothing?

And we don't know how to create a box which dark matter wouldn't pass straight through. Now I'll know how to put a positive spin on it if anyone ever plays a cruel joke by gifting me a box of nothing. There are so many interesting things in this box of purported nothingness!

It is as difficult to "imagine" nothing(ness) as it is to imagine infinity. Fettered by our dimensionality and the learned-ingrainedness of it, we are not able, the concepts are out of reach. But, BUT…worth the pondering!

Apparently, a true "nothing" doesn't exist. So, if you have any volume of space, there is always the "something" of quantum fluctuations. Perhaps the only way to get to a "nothing" is to eliminate space. And since space itself was created in the Big Bang, then presumably there could have been a "nothing" at the very first instant of our universe, but only if that "nothing" was a dimensionless point instead of the smallest chunk of space possible (i.e., if space does have a smallest quantity). But even a point could host a quantum fluctuation if that point was embedded in a different universe space. I guess the jury is still out in my mind. IF I'm not currently OUT of my mind. ;-)
