Cosmology & the Universe

Earthfiles investigative reporter Linda Moulton Howe discussed the unexplained lights coming from Ceres, new data about Saturn's moon Enceladus, and explanations for the mysterious rumbling booms and metallic sounds and their possible connection to changes in the Earth's core.

First hour guest, documentary filmmaker James Fox has an update on UFOs. He is continuing to work on his upcoming documentary/feature 701 with Tracey Torme, which explores the origins of the UFO phenomenon and the government suppression of evidence.

Cosmology & the Universe

Show Archive
Date: Wednesday - September 15, 2010
Host: George Noory
Guests: Leonard Mlodinow

Co-author with Stephen Hawking of the best-seller Brief History of Time, Caltech physicist Leonard Mlodinow discussed his current work with Hawking on the grand design of the universe and two central questions-- where does the universe come from, and why are the laws of nature what they are? Hawking's theories and the latest research in physics were used to answer those questions. While the conditions for life are just right on Earth, Mlodinow noted that we're looking backwards at the situation-- whatever conditions it took for us to get here, have already happened.

The notion of the multiverse (many universes each with their own physical laws) is a consequence of Hawking's theory of cosmology, said Mlodinow. These various universes arose from nothing, but we now understand from quantum theory that the state of nothingness is actually very unstable, and that "things are always coming and going from nothingness," he explained. Hawking's picture of the universe incorporates three theories:

  • A "no boundary" condition in which time becomes a dimension that looks like space.
  • M theory-- an extension of string theory dealing with forces like gravity.
  • Top Down Cosmology-- a new quantum approach that suggests the cosmos has many different simultaneous histories.

Mlodinow also reviewed the Big Bang theory of the origin of the universe, and the search at the Large Hadron Collider for the theoretical Higgs boson particle. Interestingly, Hawking has predicted that the Higgs particle will not be found.
