You're listening to ALL THINGS CONSIDERED from NPR News.

Time now for a change of perspective on the cosmos. Writer and astrophysicist Adam Frank says make friends with science and the ordinary, even everyday stuff, and it will transform into the extraordinary. One way to do that is by taking a new look at the stars in the sky.

ADAM FRANK, BYLINE: Stop looking up at the stars. That's no way to appreciate them. And it's no way to understand what they're trying to tell you. You see, normally, to get a view of those mysterious little points of light, you have to crane your neck. You have to tilt that big stone of a head back and look up. But let's face it. No one can sustain that head-craned-back position for very long. That's why the only way to really understand the truth of the stars is to lie down.

Now, first, you'll need to find a nice place, someplace with the darkest skies possible. It's got to be a good place to lie down, too, someplace comfortable. A wide-open field is best, but be careful about dog poop because that's going to ruin your cosmic journey right fast.

Then once you've settled down in your dark, quiet spot, take a long deep breath and face out. Face outwards, not up. You see up is just an illusion. It's a trick of the fact that you've been living on the surface of a massive rock that's been pulling you down with its incessant gravity since the day you were born. That's why you've been fooled into thinking the stars are up there, up in the sky, high above you.

Now, imagine for a moment flattening the Earth into a thick wall. Imagine that this wall is not something below you but behind you. You aren't lying down anymore. You simply have your back pressed against something. And now, what do you see in front of you? Stars. And if you look back towards your feet, what do you see? Stars. And if you look to your right or to your left or in the direction of the crown of your head, what's there? Stars.

And here's the real kicker. That wall your back is pressed up against, what's behind it? More stars. And there it is. That is the real truth. You can now feel like vertigo as you fall into the starry multitude. These stars, they aren't twinkling lights above your heard. They're all suns. They're all vast spheres of thermonuclear burning gas. And as we have just recently learned, almost all those suns support their own families of planets. All those stars, all those worlds, they're everywhere. And with your back pressed to the wall of the Earth, you can finally feel that you are there, too, right in there midst.

And now comes the next big shift. Eyes aimed forward, focus on just one star. That sun, and its likely planets, lies more than 10 trillion miles away from you. But now, look at one of its neighbors. They may look close together, but that is just another deception. That second star may be 10, 100 or 1,000 times farther away than its neighbor. All those stars, all their planets, they aren't pressed onto the surface of a dark upturned bowl. They're arrayed in the three dimensions of cosmic space like fireflies scattered across a summer field.

There is no up or down. You are not a resident of some city, some state or even some nation. You're not a Democrat or a Republican, a dockworker or a doctor. Right now, right at this very moment, you are a free agent hurtling through the midst of a vast city of stars, an all-encompassing architecture of suns. So remember, face outwards into the surrounding sky because that is your true home.
