Nothing is the Ying to something's Yang, so nothing is the inverse or the counter-point to something. Either you have something, or you have the absence of something, that is nothing.
Another way to look at it, nothing is the 'placeholder' for something, it is also the seperation (or space) between things.
Nothing is simply that with which something may or maynot exist in, we can think of space as simply nothing (in itself) that things can exist over.
But nothing can have a property (of sorts), if you consider that nothing as the gap (or space) between two somethings then you can say the property of that nothing is its length.
So in that sense, nothing is not simply just the absence of something, which is not in itself a something (nothing is not something), nothing is then just the framework or canvas in which it is possible for something to exist.
Is space and/or time nothing or something?
Say you have a box, you take out all the air and matter inside that box, a perfect vacuum, so you could say that within the boundary of that box there is nothing, or you could argue you still have heat/light, gravity etc, So lets assume you can make that box at absolute zero kelvin (no EM/heat radiation), and somehow shield it from gravity. Could you then say that within the bounds of that box you have nothing?
You could then argue that you have space and time in that box and space and time are things right?
To answer that you have to work out if nothing qualifies as something! Is the nothing between the walls of the box (the space) actually something, it contains no energy, no matter, no radiation and no gravity so is it something?
I would say that space itself is nothing, but that nothing has a length (the length of the nothing between the walls of the box).
So we HAVE to have nothing, otherwise we have no space (with a length) in order for something to exist within it.
So nothing is nothing, but it has a property. That property is the length of that nothing, that determines the size/length of the things that exist in that nothing.
You can understand solid state physics and semi-conductors with the electron-hole model, is a hole a thing? In this case a hole is just a placeholder for an electron, it is in itself not a thing. (it is the absence of a thing, in this case the absence of an electron).
An electron hole is what a virtual particle is, it is not a real thing (it is not something), but it fits an explanatory model to explain some principle.
We should do an entire show about nothing !!!
Who would have thought that nothing would be so interesting!
