When humans understood that the earth was flat and it was the center of the universe, all life revolved around that truth. Then, Galileo introduced his telescope. And with that single innovation, architecture, music, literature, science, politics - all of it changed, mirroring the new view of truth. This program is James Burke s examination of the moments in history when a change in knowledge radically altered man s understanding of himself and the world around him.

The planets of our solar system have experienced epic catastrophes throughout their long history, both raining down from outside and bubbling up from within. We’ll voyage back in time to investigate the violent events that profoundly shaped the planets, including earth itself. We’ll witness stunning revelations about what transformed Mars into a barren, hostile desert…The disaster that changed Venus from temperate to hellish…The impact that blew away Mercury’s mantle, turning it into a planetary core…A colossal disturbance that rearranged the orbits of the gas giants…Titanic impacts on Jupiter…And how a lost moon may finally explain Saturn’s rings.

A number of authors have noted that if some physical parameters were slightly changed, the universe could no longer support life, as we know it. This implies that life depends sensitively on the physics of our universe. Does this "fine-tuning" of the universe also suggest that a creator god intentionally calibrated the initial conditions of the universe such that life on earth and the evolution of humanity would eventually emerge? Some influential scientists, such as National Institutes of Health Director Francis Collins, think so. Others go even further, asserting that science "has found God."
