Tyson addressed this when standing at the Grand Canyon.
Science, however, leaves room for previous theories to turn out to be incorrect, and for unintended discoveries from seemingly unrelated work. Debates work well as a format for Ham et al., in part because young-earth creationism relies on the certainty, no matter what scientific evidence says, of a particular set of conclusions from one authoritative book (see: Ussher's ability to "identify" the time of day the earth began with just the Biblical genealogies to back him up). Without ever allowing that a young earth is possible, as Bill Nye arguably did when he participated in a creationism debate a few months ago, Tyson simultaneously presents and destroys the possibly of a 6,000 year old earth.Ībby: See, this is so much more effective than Bill Nye's well-intentioned decision to debate Ken Ham. There's no room for all those Kepler earth-like planets in a young universe.ĭanielle: I liked how Tyson quickly explained the origins of the young earth theory, and then - with the help of a deconstructed Grand Canyon - explained why it’s impossible. That universe is just a fraction of the size of the Milky Way alone, and otherwise is much less wondrous than what we have observed to be the reality. Tyson has more or less provided us with a simple visual of what a young-earth universe would have to look like. The last time Tyson alluded to young-earth creationism on the show, he explained that for a young-earth timeline to be true the edges of the visible universe would be have to be much closer to Earth - and wondered who would want to believe in a smaller universe. Basically, Ussher added up all the lives and generations as written in scripture and concluded that the Earth was created on Sunday, OctoBC, just around 6 pm.ĭanielle: I love how elegantly he dismisses this theory. This time, it's Archbishop Ussher's chronology of the earth's age based on a literal reading of the Bible. "Duck soup my ass"Ībby: Well, as has become a recurring theme, this episode directly contrasts a young-earth creationism theory with the major scientific achievements that disprove it. It's an interesting story, but not quite as interesting as what that discovery lead to: a decades-long fight between industry, the government, and scientists over the dangers of emitting lead into the environment. On this week's Cosmos: A Spacetime Odyssey, Neil deGrasse Tyson looked at how we know that the earth is 4.5 billion years old.
