Featured in hours 2 & 3, UK astronomer John Gribbin has authored books on climate change, the DNA double helix, the Big Bang, and the human condition. He said that there is overwhelming evidence that human activity is changing the climate. Gribbin thinks crop circles are a natural phenomenon, but that some are also made by humans, and was open-minded about the topic. Gribbin said he didn’t know of anyone who is trying to build a time machine, but he knows people who are working on changing time by slowing down light. He also discussed the Big Bang, and talked about other concepts of the beginning of the universe.

Linda Moulton Howe and Lucy Pringle joined Art in the first hour to discuss crop circles. Pringle has released a number of books on the circles, and flown over and visited hundreds of them. She reported on a newly-discovered formation that surpassed all of those she had seen, with 409 circles within it. Linda featured an interview with a surveyor who says it would have taken over two days just to lay out the pattern, and would be nearly impossible to plan at night.

The last 2.5 hours featured Open Lines, with many callers commenting on the crop circle phenomenon.
