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.
