Why aliens might understand the universe very differently than we do
We assume that the way humans see the world has some correspondence to objective truth. That’s not necessarily correct. Let’s do a thought experiment where we have a quick chat with an alien species to see how mistaken we are about the universe.
So we’ve made contact with aliens, and some people are celebrating and others are melting down with fear, but the overall consensus is that we should ask them over for tea or something. It’s likely that tea time conversation will be a bit stilted. What do people talk about other than what they have in common? Although we may assume that we have the whole universe in common, the aliens, if we just tweak their senses a bit, may be living in a different universe from ours.
