Ethan Siegel

Ethan has lived his life fascinated with one simple fact: we have the capacity to figure out definitive, scientific answers to even the deepest questions we can conceive about our physical reality. We do that by asking the right questions about the Universe, and then putting the Universe itself to the test. From where everything comes from to the Universe’s ultimate fate and all that lies between, he’s committed to figuring out and sharing the answers — what we know and how we know it — with anyone curious enough to listen.

A theoretical astrophysicist by training, Ethan now focuses on science communication full-time. He revels in telling scientifically accurate, beautifully illustrated stories about the Universe with the widest audience possible. He believes this Universe is the one thing we all have in common, and knowing our shared cosmic story should be for absolutely everyone, regardless of age, gender, race, religion, nationality, sexuality, education, or economic background.
