Astronomy writer James Mullaney discussed his book Edgar Cayce and the Cosmos, which examines the "Sleeping Prophet's" readings about the universe. As a scientist, he was initially skeptical about the Cayce material (which was delivered in a trance state), but upon study, he was won over by its accuracy and insights.

Some highlights he presented from Cayce's readings:

• Someone in antiquity had a telescope, but it was found rather than built by that person's civilization.
• There is no life like ours in the solar system, but there are other beings/civilizations elsewhere in the universe.
• The stars and planets do not govern our future.
• In a sense, sunspots are caused by the turmoil of the human race.

Cayce, who died in 1945 and often spoke of past lives in his readings, may have reincarnated on another world, Mullaney suggested. Cayce's entire 14,306 readings are available on a searchable CD-ROM, which Mullaney said he used in his research.

Signal from Space

First hour guest, astronomer Seth Shostak of SETI commented on a mysterious space signal picked up by an Australian facility back in 2001. Recently, it was speculated that the brief radio burst might have been a sign of ET intelligence. However, Shostak suggested the most likely explanation for the burst was that it was caused by the collision of two neutron stars.
