The other day, whilst in a philosophical mood, I got to musing on whether there would be any way for humans to tell if we were being kept as pets by some alien intelligence.
Consider the goldfish that we keep in our kitchen.
I doubt that they have even the foggiest idea that the glass-walled vessel in which they find themselves is in any way strange. Or even that they have any idea of what ‘glass’ is, or what ‘strange’ is. They are quite obviously accustomed to the large shadowy figures that loom over them from time to time, and have come to associate these figures with food, which makes for obvious excitement for them. Their goldfishy brains probably can’t even encompass the idea of humans, or a kitchen bench, or meatballs and tomato sauce (which is what I happen to be cooking for dinner as I write this).
But what if we are like that? If we were the pets of aliens, how would we even know? Our puny human brains might be to them as goldfish brains are to us. If we are being kept in the alien equivalent of a glass tank on an alien kitchen bench, how could we even know, if we are unable to contain the concept of alien glass, or alien kitchen benches or alien meatballs? If we know nothing other than the circumstances in which we find ourselves – like the goldfish, raised in tanks in an aquarium and transported in plastic bags to a new home – what possible reference point could we have?
As silly as this sounds, I don’t mean it to be a flippant question. It is at least as plausible as any other hypothesis for why we are here, and it is just as unfalsifiable as postulating the existence of God, or alternative universes, or that we are a computer simulation.
If you accept that there are grades of intelligent awareness possible in the universe (and our own experience tells us that goldfish seem to be less aware of the universe than we are, and at the same time more aware of the nature of things than bacterium, say, so that appears to be a fairly reasonable assumption) then putting ourselves at the top of the intelligent awareness ladder seems a tad presumptuous. Is there any way, therefore, to know whether our reality is a ‘natural’ one or whether we are in an alien goldfish bowl?
I suspect not. But the places to start looking would be things in our universe that seem to be a little too ‘convenient’ for us to be here. And there are, indeed, some of those.
