The Human Impact of Discovering Alien Life, with Astrobiologist Steven J. Dick

Our universe is made up of billions of galaxies. The cosmos is so mind-bogglingly vast, that it’s hard not to suppose that we aren’t alone, that life must exist somewhere else besides our own planet. Last month, some of the world’s leading scientists gathered at an Astrobiology Symposium run by NASA and the Library of Congress to discuss where we stand in our search for extraterrestrial life. This week on Point of Inquiry, Steven J. Dick, the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology, discusses the progress that has been made in the search for extraterrestrial life, and what the potential ramifications may be if and when we make this most monumental of discoveries — that we are indeed not alone.
