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 have never observed infinity in nature. Whenever you have infinities in a theory, that’s where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it’s instantaneously, infinitely big. It seems absurd.” -Janna Levin You’ve likely heard…

“Whether humans are responsible for the bulk of climate change is going to be left to the scientists, but it’s all of our responsibility to leave this planet in better shape for the future generations than we found it.” -Mike Huckabee It only makes sense that scientists should debate and argue over the findings in…

“There is always a heavy demand for fresh mediocrity. In every generation the least cultivated taste has the largest appetite.” -Paul Gauguin From our vantage point within the Milky Way, it sure does appear impressive. Hundreds of billions of stars shine in our own cosmic backyard, with our galaxy spanning a whopping 100,000 light years…

“Time travel used to be thought of as just science fiction, but Einstein’s general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.” -Stephen Hawking As always, there’s been a new fantastic week of articles here at…

“I long ago abandoned the notion of a life without storms, or a world without dry and killing seasons. Life is too complicated, too constantly changing, to be anything but what it is. And I am, by nature, too mercurial to be anything but deeply wary of the grave unnaturalness involved in any attempt to…

“One of the great things about music is that it has the capability of time travel – you smell a certain smell in the room and it takes you back to your childhood. I feel like music is able to do that, and it happens to me all the time.” -M. Ward Have you ever…

“The experiments that we will do with the LHC [Large Hadron Collider] have been done billions of times by cosmic rays hitting the earth. … They’re being done continuously by cosmic rays hitting our astronomical bodies, like the moon, the sun, like Jupiter and so on and so forth. And the earth’s still here, the…

“You must remember, my dear lady, the most important rule of any successful illusion: First, the people must want to believe in it.” -Libba Bray There are many times throughout history that science — and scientists — have gotten it wrong. And there are many topics today that are quite polarized, from the Big Bang…

“I was always amused when overtaking one of these great monsters [a tortoise], as it was quietly pacing along, to see how suddenly, the instant I passed, it would draw in its head and legs, and uttering a deep hiss fall to the ground with a heavy sound, as if struck dead. I frequently got…

“A few centuries ago, the pioneer navigators learnt the size and shape of our Earth, and the layout of the continents. We are now just learning the dimensions and ingredients of our entire cosmos, and can at last make some sense of our cosmic habitat.” -Martin Rees You might think that Jupiter is the largest…
