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.

"They most likely form as subsystems within looser associations and evolve by gravitational processes. Strong galaxy interactions result and merging is expected to lead to the ultimate demise of the group. Compact groups are surprisingly numerous, and may play a significant role in galaxy evolution…

“Life and death matters, yes. And the question of how to behave in this world, how to go in the face of everything. Time is short and the water is rising.” -Raymond Carver As we make our way through October, Halloween approaches here at Starts With A Bang! But as eerie as the world and our Universe…

"There have to be moments when you glimpse something decent, something life-affirming even in the most twisted character. That's where the real art lies." -Martin McDonagh There is a whole lot of cosmic detective work we can do to figure out the history of the Solar System. By examining the fossil…

“What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as earth and ice, water, fire and air, a quintessence, pure spirit, resolving into no constituents.” -Jay Griffiths At the earliest times, we can trace the history of our Universe…

"You are both fools. You cannot see thoughts, or angels. One is an abstract, the other a fantasy. To compare the two would be silly. Of course, using inferential logic, we can detect the existence of thought by the evidence of its actions, just as I detected the existence of a new form of radiation…

“She didn’t even know what she’d do when she got back to New Orleans, but inside she felt a yearning to shove her hands in the dirt, to cling to the ground there, forever.” -Sarah Rae Hurricanes are among the most destructive natural disasters to occur on Earth, with extensive flooding, property…

"'Topology is destiny,' he said, and put the drawers on. One leg at a time." -Neal Stephenson If you want to understand the Universe, there are two big areas you need to know: Einstein’s theory of general relativity, which governs the gravitational force and the curvature of spacetime, and quantum…

"If you are fearful, a horse will back off. If you are calm and confident, it will come forward. For those who are often flattered or feared, the horse can be a welcome mirror of the best in human nature." -Clare Balding One of the most iconic astronomy images is that of the Horsehead Nebula.…

“Put two ships in the open sea, without wind or tide, and, at last, they will come together. Throw two planets into space, and they will fall one on the other. Place two enemies in the midst of a crowd, and they will inevitably meet; it is a fatality, a question of time; that is all.” -Jules Verne…

"There will be peace when the people of the world, want it so badly, that their governments will have no choice but to give it to them. I just wish you could all see the Earth the way that I see it. Because when you really look at it, it's just one world." -Superman So, you want to shoot Earth’s…

“Everyone has his dream; I would like to live till dawn, but I know I have less than three hours left. It will be night, but no matter. Dying is simple. It does not take daylight. So be it: I will die by starlight.” –Victor Hugo Whether you’re at rest or in motion, you can be confident that — from …

"Nothing in the standard cosmological model predicts this, and it is almost impossible to imagine how that model could be modified to explain it, without discarding the dark matter hypothesis completely." -David Merritt Dark matter is a hugely successful theory for explaining a whole slew of…

"Teaching man his relatively small sphere in the creation, it also encourages him by its lessons of the unity of Nature and shows him that his power of comprehension allies him with the great intelligence over-reaching all." -Annie Jump Cannon A look up at the stars in the night sky shows a clear…

"Alexander Hamilton and Thomas Jefferson hated each other so much. But that hate that they had for each other did not come before the love of their country." -David Scott You can't make America great 'again' without looking at what made us great in the first place. It wasn't industry or…

"We conducted the first fully blind, three-dimensional search for cool gas in the early universe. Through this, we discovered a population of galaxies that is not clearly evident in any other deep surveys of the sky." -Chris Carilli The Hubble Ultra Deep Field and its successor images represent…

“To study things from a scientific standpoint means to take an inventory of them—to find the process in which they are being produced; to connect them with other things; to see things in their causal process. ” -William Harris As is pretty much always the case, it's been a big week here at Starts…

“Between cold fusion and respectable science there is virtually no communication at all. …because the Cold-Fusioners see themselves as a community under siege, there is little internal criticism. Experiments and theories tend to be accepted at face value, for fear of providing even more fuel for…

“Alone, I often fall down into nothingness. I must push my foot stealthily lest I should fall off the edge of the world into nothingness. I have to bang my head against some hard door to call myself back to the body.” -Virginia Woolf If you think about the Universe, what it is today, what it…

“All I want is blackness. Blackness and silence.” -Sylvia Plath Even on the darkest night skies from the most pristine locations on Earth, the night sky is never truly dark. Not even if you look away from the plane of the galaxy, on a moonless night, between the stars and away from any human-made…

"Science cannot tell theology how to construct a doctrine of creation, but you can't construct a doctrine of creation without taking account of the age of the universe and the evolutionary character of cosmic history." -John Polkinghorne What is the Universe? What are those points of light in…

“It may be that ultimately the search for dark matter will turn out to be the most expensive and largest null result experiment since the Michelson-Morley experiment, which failed to detect the ether.” -John Moffat Dark matter is a puzzle that’s now more than 80 years old: the presence of all the…

“When we think about the present, we veer wildly between the belief in chance and the evidence in favour of determinism. When we think about the past, however, it seems obvious that everything happened in the way that it was intended.” -Michel Houellebecq If you take anything in the Universe and…

“When you arise in the morning, think of what a precious privilege it is to be alive — to breathe, to think, to enjoy, to love.” –Marcus Aurelius How old is life on Earth? If all you had to go on was the fossil record, you’d run into severe trouble once you went back more than one or two billion…

“Maybe some people don't feel scared when they think about comets and supernovas. Maybe they think it is wonderful.” -Lydia Netzer What, in our Solar System, has a long tail from boiled-off frozen ices? What simultaneously leaves an X-ray signature when the solar wind collides with those boiled-off…

“It matters not what someone is born, but what they grow to be.” -J.K. Rowling From 19,000 light years away, Terzan 5 looks a lot like pretty much any globular cluster you'd expect to find: it's massive, concentrated, with a huge number of stars at right around 12 billion years of age. But mixed in…
