Some light philosophical exploration for the weekend.
In everyday life, we all learn that an empty glass still is full of air. If you do it in space, when you remove the air, current physics says that even the vacuum is still supposedly full of virtual particles popping in and out of existence and some scientists are trying to harness vacuum energy to power spaceflight. So the meaning of nothing has changed quite a bit.
My own sci-fi Space Anchor invention uses this principle too, using stacks of Casimir combs that vibrate in such a way that virtual particles can pop into existence and are separated before they can annihilate. This locks the anchor onto the local space time fabric at a quantum level and the anchor then moves with the local space time or can lock on and pivot around a point in space. Dynamic changes in spacetime curvature caused by the movements of stars and planets are used to propel the spacecraft (called the C14). Well, it might work. Nature abhors a vacuum but it won’t let you steal it. You won’t ever see a ‘404 space not found’ error. There might be nothing of any substance in that particular bit of space, but when you prevent those virtual particles that pop up from annihilating and try to move them away, you can’t. The space anchor behaves as a space anchor.
Even in the space between Casimir plates, where virtual particles can’t form, there isn’t nothing. It still has coordinates. These might only be a human construct, but the emptiest space in nature still is full of mathematics, coordinates, equations, references, still potentially full of virtual worlds, in the new sense of virtual, the cyber sense.
To prevent that, the space would need to be virtual itself. It can’t be part of the physical universe, because then it would have a location and an address and coordinates. It needs to be a virtual one to have any chance.
So what about a place in virtual worlds? Can you make an empty box there? A cyberspace world has whatever physics the designers give it. Portal links places together in ways that aren’t possible with normal physics, but they are still navigable. You can work out a route from A to B. In the 1970s computer adventure game, Classic Adventure, you’d find yourself at some point lost in a Maze of Twisty Little Passages. Eventually you’d figure out that and the Twisty Little Maze of Passages and the Maze of Little Twisty Passages were all different locations, 16 in all, and you’d draw a map and escape. To be truly nothingness, it mustn’t be on a map or have any sort of coordinates, not even ‘close your eyes, spin round three times and click your heels’ coordinates.
So, our empty place full of nothing is virtual, in a virtual world, but you can’t get there using any kind of map, it mustn’t have any kind of reference or coordinates by which you might find it. It can be done. A game could randomly spawn random places on a strictly non-repeatable basis with one-time random algorithms, and nobody could ever find one except by accident because it isn’t connected in any way at all to anywhere else and there is nothing there, nothing at all. No light or darkness even, no visual descriptors, no smells, no texture, no temperature, no properties, no coordinates, no space-time. Nothing, absolutely nothing. That could be done.
So we could make nothing, in cyberspace. But you can’t describe it or imagine it and you could only find it by the most unlikely of accidents.
Like most philosophical problems, trying to solve it just causes more questions. If nothing exists but it can’t ever be found except by a rare accident, does it become the hottest property in existence, and does it cease to be nothing when you find it?
