This has been on my list-of-stuff-to-watch for a long-ass time, and I finally got around to watching it. I liked it a lot.
Preface: I tend to believe that certain “philosophical realizations” really depend on what certain concepts and words mean to the realizer, and this is something that is unique to everybody. Thus, I don’t really believe that because something seems-right and makes-sense to me that I can necessarily tell it to other people hand have them go “oh my, you’re right.” And even if I could, I don’t know if such transmission would be meaningful to the reader, because with these philosophical realizations the journey to the conclusion seems more important than the conclusion. I guess what I’m saying is that this is all just philosophical-masturbation and although I wouldn’t mind if anyone takes away anything useful from it, I won’t consider myself a failure if nobody does.
Definition of Terms: When I say the universe, I mean all contiguous time and space. If there are wormholes that lead to another “universe” then they are the universe as well, because we can (in theory) got there. If there was another universe before the big bang that led to this universe, then that is part of this universe as well, because it is part of the timeline of this universe. Thus “universe” as I use the term could be defined as “anything that can be theoretically seen or touched by us, or ever could have been, or ever will be.” If there is a God (and I’m not saying there is) then he/she/it is part of the universe as well.
The Argument: It doesn’t make any sense to ask where the universe is, because the universe is all of space. The universe isn’t to the left of anything, or to the right of anything, or on top of or below anything. The concept of “where” doesn’t make sense beyond space itself. It also doesn’t make sense to ask when the universe was created, because the universe is time itself. Either there are a distinct number of incarnations (e.g. one big bang to start it all, one big crunch to end it all) or there are an infinite number (one universe leads to another, going back an infinite amount and going forward and infinite amount) but either way, that totality of being doesn’t have anything before it or anything after it, so it doesn’t make sense to ask when it started. The universe may have start and end dates to us within the universe (the big bang happened on a Thursday) but it doesn’t make sense to say something like “there was no time and space, and then 5 minutes later the universe started.”
What does it mean to say something exists? I think of that quote by Philip K. Dick: “Reality is that which, when you stop believing in it, doesn't go away.” I tend to think of reality as anything you can poke with a stick. Another way to say it is that anything that has a cause, and that can cause other things, is real. All of these definitions of reality (and I challenge anyone to come up with a definition that doesn’t) depends on a tester that is already presumed to be real. If you poke something with a stick to see if it is real, it presumes that the you and the stick are also real. In other words, something is real if it is real to other real things. Yet if the universe is the totality of all things that could possible effect each other, then it couldn’t possibly meet any of those tests. You can’t go outside the universe and poke it with a stick. There is nobody outside the universe who can stop believing in the universe to see whether it goes away or not.
“Real” or “exists” are terms that only mean anything within the universe. The universe cannot properly be said to exist, nor to not-exist. To ask whether the universe exists is like asking if your coffee-cup is happy or sad: it just doesn’t apply.
Up Means Everything and Nothing: I’m getting this impression that every adjective has three spheres. In one sphere, it means one particular, objective thing. In another sphere, is has a nebulous meaning. In another sphere it is meaningless. Take “up.” For example. For you, where you stand on the Earth right now, up is one particular direction: a line extending from the center of the Earth, to you, and up into space. For you and other people on the same continent as you, up is a general sort of direction. If you pointed straight up in California, you would be pointing in roughly, but not quite the same direction, as someone pointing up in New York. When you talk about everyone in the world, though, up has no objective meaning. Any given vector line could be up to someone on Earth.
The word “exists” is the same: within the universe it is important whether something exists or not, but at the level of the universe, it is a meaningless term.
So What Does This Mean: Accepting that the universe doesn’t exist as fact doesn’t really mean or do very much. It means one doesn’t have to spend time worrying about why the universe exists in the form it does (if it doesn’t exist, there is no ‘cause’ in a cause-and-effect sense, and so no why). It doesn’t mean that we can make bullets stop Matrix-style because they don’t really exist, because although neither we nor the bullets truly exist in a cosmic sense, within the universe we exist to each other.
To me, the value is that it teaches me to stop looking for cosmic absolutes. Democritus said “Nothing exists except atoms and empty space; everything else is opinion” yet if we accept that the universe doesn’t exist, then not even the atoms and empty space are a done deal. It doesn’t make sense to look for cosmic truths, only for local truths, truths that are true within the sphere that we inhabit.
When (if) we get our new place we should build a
Goat Tower.

vampyrecat, I'll let you spearhead this.
