Welcome to part 2 of Random Musings of a Truck Driver. My series of philosophical and pseudo scientific (at best) ramblings. Last time I talked about time, this time I'm going to talk about nothing. *insert joke about most of my posts being about nothing*
Does nothing exist? Is it real or an abstract? For that matter, what even is nothing? When we say "nothing" what are we talking about? You can walk into a room completely devoid of furniture and say that nothing is in the room. Even ignoring that you are in the room, the room still has air in it. Okay, let's say we are talking about a vacuum. So we hop in our trusty space ship and blast off into the solar system, nowhere near any planet, asteroid, or comet. So what's out here, outside the space ship, is that nothing? It may be devoid of matter, but it probably still has some radiation and/or energy. Okay, let's go further into interstellar space, or even intergalactic space, surely out here we can find a pocket of space that is a true hard vacuum, right? For the sake of this thought experiment let's say we do find said hard vacuum, surely this is nothing, right? Well, according to quantum field theory even the vacuum itself has a field and a zero point energy, so isn't that something and if so that means even a hard vacuum isn't "nothing". Can we have nothing anywhere in our universe? Wouldn't there always be, at the very least, spacetime itself and the zero point energy of the vacuum? The next question might be "what about outside the universe"? What is outside the universe or if there even is such a thing as outside the universe goes beyond the scope of this post, so I won't go there (yet?).
Even just the concept itself, can nothing, truly nothing, the absence of absolutely everything exist? If there isn't anything at all then how can it exist? So I guess my conclusion is that nothing doesn't exist as anything more than an abstract.
