Ethan Siegel

Ethan was born in New York City as the son of a Jewish postal worker. He did his undergrad at Northwestern, taught public school in Houston, Texas and Los Angeles, California, before moving to Florida, where he got his PhD in theoretical astrophysics at the University of Florida. After that, he moved to Madison, Wisconsin, where he taught at the University of Wisconsin, ate too much cheese, and also met his life partner, Jamie. After working in astrophysics research at the University of Arizona and starting the world-renowned science blog, Starts With A Bang, he moved from the hellish desert to rain-soaked Portland in 2008. Since then, he's been a professor at the University of Portland and Lewis & Clark College, grown a nationally renowned beard and mustache, got invited to join a circus and probably drank more beer than a healthy person should. He currently works as the head curator at Trapit, and can't wait to tell you a little bit more about the Universe.

"We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light." -Plato Imagine, if you will, the year 2200. Forget about the flying cars and robotic exoskeletons, though. I'm thinking about the incredible scientific tools we'll have at our…

He was a dreamer, a thinker, a speculative philosopher... or, as his wife would have it, an idiot. -Douglas Adams When I started writing about science online in January of 2008, I put the word out that I would accept questions from my readers. After all, I knew that there was a lot of…

"Books serve to show a man that those original thoughts of his aren't very new after all." -Abraham Lincoln Last weekend, I presented you with two remarkable covers, one from music and one from astronomy. This week, I'm going to show you the reverse of that; going back to the forgotten originals.…

Yo ho! It's hot, the sun is not a place where we could live. But here on earth there'd be no life without the light it gives. We need its light. We need its heat. We need its energy. Without the sun without a doubt there'd be no you and me. -They Might Be Giants Ahh, the Sun. Beautiful and blinding…

"Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now.

"To exist in this vast universe for a speck of time is the great gift of life. Our tiny sliver of time is our gift of life. It is our only life. The universe will go on, indifferent to our brief existence, but while we are here we touch not just part of that vastness, but also the lives around us…

"Any red-blooded, flag-fearing American would love the M-320. Celebrate the independence of your nation by blowing up a small part of it." -The Simpsons There are many things that your life has to offer as far as fun goes, and it's different for each person. For me, music is a huge part of it. Here…

"Prediction is very difficult, especially if it's about the future." -Neils Bohr As many of you know, the Big Bang is one of the most powerful scientific theories we have. It's also one of the most unsettling. The idea that our entire Universe -- filled with practically a trillion galaxies -- is…

The task is not so much to see what no one yet has seen, but to think what no body yet has thought about that which everyone sees. -Arthur Schopenhauer Most of you who've been reading Starts With A Bang for a while have seen this picture come up many, many times. Why do I keep putting it up, and…

"Voyagers discover that the world can never be larger than the person that is in the world; but it is impossible to foresee this, it is impossible to be warned." -James A. Baldwin Sometimes, good things happen. And sometimes, you need to get out there, however down you're feeling, and make them…

A person without a shadow should keep out of the sun, that is the only safe and rational plan. -Adelbert von Chamisso A few years ago, there was a rumor going around that the Earth's axis had shifted, and that we were no longer inclined to the Sun at 23.5°. Well, guess what? Today, June 21st, like…

"If we lived on a planet where nothing ever changed, there would be little to do. There would be nothing to figure out. There would be no impetus for science. And if we lived in an unpredictable world, where things changed in random or very complex ways, we would not be able to figure things out.…
