We are not simply in the universe, we are part of it. We are born from it. One might even say we have been empowered by the universe to figure itself out - and we have only just begun.

Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.

Part of me thinks that I've been called by the universe, to get all sort of spiritual about it. Like, I've had no actual say in the matter. The universe found me.

To view space as, "Well, let's go to Mars now," or "Let's do this now," maybe we should rethink of space as our backyard and have a suite of launch vehicles that can enable any ambition a person has regarding space. It's the same way you can go to buy a car: I want to go offroading, I'll buy this model. I'm a city driver, that's this model. I want to use less fuel, well, that's this model. They're not selling you one car, you have options. So when I think of space, I think of having options.

Like a snowplow in overdrive, a supernova shockwave might sweep away any gas clouds in its path.

Whether or not you can never become great at something, you can always become better at it. Don't ever forget that! And don’t say “I’ll never be good”. You can become better! and one day you’ll wake up and you’ll find out how good you actually became.

You know, dark matter matters.
