There are two questions that get to us all: Are we alone in the Universe? And, where did we come from? For me, science provides a much more satisfactory way to seek answers than does any religion I've come across. With that said, the universe is mysterious and wonderful. It fills me with reverence for nature and our place among the stars; our place in space.

I've always loved airplanes and flight. The space program was really important to me as a kid. I still have a photo of Armstrong and Aldrin on the moon in my living room.

Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.

Bicycling is a big part of the future. It has to be. There's something wrong with a society that drives a car to work out in a gym.

You and I are made of stardust. We are the stuff of exploded stars. We are therefore, at least 1 way that the Universe knows itself. That, to me, is astonishing.

When or if answers are found, you can be assured those answers will lead to more questions. Is the troubling or wonderful? It depends on your view of your place in nature, your place among the stars; I suppose.
