Sunday, August 19th 1pm TX/RX Labs John Moffitt Presents: “Earth Extinction Events, Past and Future” (one hour).

Let’s takea look at the very big picture on Earth during its last three orbits around the Milky Way galaxy … and even go a bit into the future. Many are familiar with theories of a very few recent extinction events, but less are aware that Earth’s past is filled with a far more complex pattern of extinction events and probabilities. Geologist,paleontologist and astrophysicist John Moffitt will examine paleogeography and astrophysics in the context of our complex solar system. You will learn how life on Earth has been significantly affected by the geometry and violence in a very crowded solar neighborhood. John plans to open eyes, allowing us to see how fluid conditions are for life on Earth and just how dangerous our home is.
