Imagine you’re an environmental studies professor. Every semester you're faced with a roomful of idealistic students. You then have to present to them the grim forecast that climate scientists expect. These students may have known the planet faces challenges - but this is bad. And that, says Dr. Sarah Jaquette Ray , is where things might go sideways. "They become fatalists in the face of no easy solutions," says the environmental studies professor.

"If we look at what makes up the universe, it's a little disturbing," Humboldt State University physicist CD Hoyle told the standing-room-only audience in Arcata. "It turns that most of the universe is dark energy." And we don't know what that is. "And that's a problem." Physics has problems, and nature is hinting at mysteries as big as the universe itself.
