Theoretical physicist and popularizer of science, Dr. Michio Kaku, discussed the latest science stories in the news, including monster solar flares, and the search for dark matter. Lately, the sun has been throwing "temper tantrums," with some very large solar flares, he said, and as we head into the maximum of the sunspot cycle, "the fear is that one of these solar flares could hit the Earth," like the event that occurred in 1859, which fried telegraph wires. He also noted that the asteroid Apophis could be a threat to our planet when it flies by in 2029, and again in 2036, though the odds have diminished somewhat that it will be a direct hit. Regarding parallel universes, string theory might eventually prove their existence in other dimensions, he said. As to the concept of the "multiverse," our universe could be considered like a bubble, and there could be other bubbles existing in a kind of bubble bath, he explained, and sometimes these bubbles bump into each other resulting in something like the Big Bang. What existed before the Big Bang? "We should find evidence of an 'umbilical cord'...perhaps connecting our universe to a parallel universe," he posited. NASA is considering launching LISA, a laser space antenna that could reveal data of our cosmological origins, he reported. Beyond the Higgs, he spoke about the next set of particles that could be discovered by the Large Hadron Collider. Called sparticles or super particles, they are "the next octave on the string ...
