November 23, 2015: Dr. Michio Kaku

Art Bell welcomes theoretical physicist Dr. Michio Kaku for a wide-ranging discussion on the frontiers of modern science. They begin with the mysterious dimming of Tabby's Star, where starlight dropped by an unprecedented 22 percent, leaving astronomers without a conventional explanation and keeping the possibility of an alien megastructure on the table.

Dr. Kaku outlines his classification of civilizations by energy use, placing humanity at a Type 0.7 on the Kardashev scale and roughly a century from reaching Type 1 status. He identifies the internet, global trade blocs, and international sports as early markers of a planetary civilization, while noting that terrorism represents resistance to that transition. The conversation moves through nuclear weapons policy, third-generation warheads, and the legacy of scientists who built the atomic bomb.

The discussion turns to neuroscience and the future of the mind, including recorded memories in mice, brain pacemakers for Alzheimer's patients, and the scientific verification of lucid dreaming. Dr. Kaku describes a coming era of Brain Net, where emotions and memories could be transmitted online. He also addresses fusion energy research at ITER, the stalemate at Fukushima, and the Large Hadron Collider's search for evidence of string theory and higher dimensions.
