Cause it's cool

Why exploring space is so important. And a bunch of stuff about the Copernican formula.

I like that he’s so precise about the 46 years part. And this quote:

If it’s true that civilizations normally go extinct because they get stuck on their home planets, then the odds are against us, but there’s nothing inevitable about the Copernican Principle.

That’s a pretty big if. If only the Romans and Persians and Assyrians and Phoenicians and Hittites had explored space more, they might have fared better.
