The human brain craves the sensation of knowing like a drug addict craves the next fix. If real knowledge is uncomfortable or not at hand, we are quite content to just make something up, then convince ourselves it’s real. In a world where knowledge matters, that’s dangerous.
The iconic saguaro cactus gives the desert an otherwordly beauty. That beauty does not exist in isolation. It embodies the fascinating and awe-inspiring processes that have shaped the universe, going all the way back to the Big Bang itself.

Looking at room full of amateur astronomers, gathered for the Okie-Tex Star Party under the spectacularly dark skies of the Oklahoma Panhandle, I am reminded of my own roots and those who helped me discover the universe.

A strong fight-or-flight reaction served our evolutionary ancestors well. If the leopard catches you, that’s it! But today a visceral response to a not-so-mortal threat seldom improves things. If you want to get a handle on those intense, counterproductive bouts of emotion, start by understanding where fight-or-flight came from in the first place.
Alone, 100 feet underwater, with a shark in its element, I am overwhelmed by a mixture of awe, beauty, joy, and intellectual wonder at the world that brings us together. In that moment, I experience just what science is all about.

Chaos is a sticky wicket for science. There are things a correct theory like climate change cannot predict, but there are a lot of things that it can. It’s important to understand which is which.

For biological organisms, interstellar travel is hopelessly difficult, and probably pointless. For sentient machines, however, home is the environment you were built for.

It would be fun to think there is a flourishing interstellar civilization of humanoid aliens out there. But then it would also be nice to believe in unicorns and midichlorians. It would be nice, but they probably aren’t there.

Gilding the lily makes everybody look bad. When the Laser Interferometer Gravitational-Wave Observatory detected ripples in the fabric of space-time from a pair of merging black holes, it was a technological and scientific accomplishment without peer! But LIGO did not “discover” gravity waves.

Fundamental change is always messy. As science tackles the complex processes that shape the real world it is having to reinvent itself on the fly. Welcome to the Wild West!

As science has evolved from simple observation to deep understanding, each new way of thinking about the world has transformed not only science, but human society. That evolution is far from over.

Over his 30 year career as an internationally known astrophysicist, Dr. Jeff Hester was a key member of the team that repaired the Hubble Space Telescope. With one foot always on the frontiers of knowledge, he has been mentor, coach, team leader, award-winning teacher, administrator and speaker, to name a few of the hats he has worn. His Hubble image, the Pillars of Creation, was chosen by Time Magazine as among the 100 most influential photographs in history.
