http://www.netflix.com/Movie/Origins_Nova/70018490
Hosted by astrophysicist Neil more...deGrasse Tyson, this program reveals the origins and mysteries of the cosmos. The series examines how the Earth was formed, how life on Earth began, the possibility of extraterrestrial life and how the Big Bang resulted in inhabitable planets. Join the scientists as they try to capture echoes of the Big Bang, pose the question "Do aliens already walk among us?" and dig into dozens of other mind-blowing topics.
"A Conversation With Neil deGrasse Tyson"
Neil deGrasse Tyson is used to wearing a lot of hats. He is a leading astrophysicist, the director of the American Museum of Natural History's Hayden Planetarium, a columnist for Natural History Magazine, and the author or coauthor of six books. As host of NOVA's "Origins" miniseries, Tyson donned yet another hat, one that forced him to suppress his customary outspokenness to serve as dispassionate guide on a journey into the mysteries of the universe, the Earth, and life itself. In this interview, Tyson returns to his old self, holding forth on why he's not convinced there's intelligent life beyond Earth, why he feels role models are overvalued, and how he copes with the astronomical numbers that swirl around his head every day.
The start of everything
NOVA: What makes the study of origins so hot right now?
Tyson: Well, one thing that distinguishes us today from the discoveries of the past is the extent to which the exploration of the universe has become multidisciplinary. It was unthinkable not long ago that a biologist or paleontologist would be at the same conference as an astrophysicist. Now we have accumulated so much data in each of these branches of science as it relates to origins that we have learned that no one discipline can answer questions of origins alone. It requires the additional insights that one gets by merging not only the questions, but the answers, among scientific disciplines.
Now, for example, when you look for life on Mars, you need the astrophysicist to characterize the environment in which the planet is found. You need the chemist to understand the chemistry of the soils. You need the geologist to understand the rock formations. You need the biologist, because no one else will know what life will look like. You might even need a paleontologist to look for life that doesn't exist there today but might have left fossil remains.
NOVA: It's hard to imagine scientists in such diverse disciplines working well together. Do they?
Tyson: Initially it was like a shotgun wedding, where you'd say, "Well, I guess we have to talk to each other." And scientists in different disciplines don't speak the same language. They publish in different journals. It's like the United Nations: you come together, but no one speaks the same language, so you need some translators.
"The moons of the solar system may be more interesting than the planets themselves."
But in the end, what happens is that new fields of astrobiology and astrogeology and astroparticle physics arise, and they begin to develop their own language that represents the intersection of the two—say, between astrobiology and biology. That's when you know you've created a new subdiscipline, or even a brand-new discipline.
NOVA: What are some of the most exciting recent discoveries in origins science?
Tyson: I would say one, we nailed the age of the universe. Two, we have measured the existence of dark matter and dark energy. Even though we don't yet know what they're made of, we know we can measure the effects they have on the origin and evolution of the universe. Another is the discovery that the moons of the solar system may be more interesting than the planets themselves.
NOVA: How so?
Tyson: It's contrary to our earliest expectations. We used to think, Our moon is dry and barren, so why should we believe anybody else's moon is interesting? But if you loo less
