Revolutionary discoveries don't always breakthrough the hustle of daily life.

After all, when the Wright Brothers lifted their rickety plane off the sands of Kitty Hawk, the rest of the world was just out buying their eggs, milk and toilet paper. On that day who knew — or could imagine — that decades into the future millions of people would be sitting in giant jet-planes watching Direct TV and soaring five miles above the planet's surface.

ARI SHAPIRO, HOST:

You are trapped in space. Seriously. You're captured, cornered, mired. You're totally stuck and there's not a damn thing you can do about it.

You're trapped in space and what that really means is you're trapped in three dimensions.

To get a gist of what I'm talking about, imagine for a moment you're walking through the woods and a bear magically appears in front of you.

To escape this angry bear, which direction would you run?

Does the size of space — those zillions of stars and zillions of miles of nothing between them — freak you out?

Well, if it does, guess what?

You're not alone.

I give a lot of public talks about the universe. Really. It's in my job description:

  • Astronomer. Check.
  • Study stuff in space. Check.
  • Give talks about universe. Check.
