Blindingly obvious

Assume there are infinite universes. You don’t actually have to believe this. Just… imagine. Infinite universes with infinite possibilities. We’ll call it the multiverse.

Let’s imagine we map all the moments in the history of our world to separate universes. So what happened five minutes ago? Different universe. And it might as well be, right? We can’t access the past in any real way other than looking at history and memories.

Take a universe from, say, 500 years ago. It’s not super important when, but a few hundred years seems good for illustrative purposes. It’s quite a bit different. Imagine being able to go from this universe to that universe and have a conversation with a someone. Anyone. Doesn’t matter who.

Think about all the things that are blindingly obvious to you. The earth goes around the sun. Stuff is made of smaller stuff. Time is relative. Democracy is the best form of government. Free speech is sacred. Whatever. Stuff you think is kind of axiomatic. Imagine explaining these things to that someone.

How might that go?

Well, probably not very well. Things aren’t blindingly obvious instantly. In fact they’re not even blindingly obvious from culture to culture in the here and now, especially when you move away from rigorously provable things like “the earth goes around the sun”.

Now imagine someone comes from a future universe to talk to you. They start telling you stuff that seems blindingly obvious to them.

How might that go?

Again, probably not well.

Why is that?
