Never Discount the Impossible
Mar. 4th, 2008 12:53 pmMichio Kaku, in his new book, Physics of the Impossible, warns us that nothing should be considered impossible or beyond our eventual understanding. "In my own short lifetime," he writes, "I have seen the seemingly impossible become established fact over and over again."
Kaku, a professor of theoretical physics at the City University of New York and world-renowned author of "Parallel Worlds," "Beyond Einstein" and the bestselling "Hyperspace. " Kaku pioneered string field theory and is now working on the fabled Theory of Everything (a union of gravity with the three other fundamental forces: electromagnetism and the strong and weak nuclear forces).
In "Physics of the Impossible," Kaku divides the "seemingly impossible" into three classes.
Class I consists of technologies that "might be possible in this century," including "teleportation, antimatter engines, certain forms of telepathy, psychokinesis, and invisibility." Class II awaits the wisdom we will have acquired in "millennia to millions of years in the future" and includes time machines, hyperspace travel and popping through wormholes in space into another universe. Class III is the "perpetual motion machine" and precognition. Kaku concludes that if "they do turn out to be possible, they would represent a fundamental shift in our understanding of physics."
Soon, Kaku belives, humanity may face an existential shock as the current list of a dozen Jupiter-sized extra-solar planets swells to hundreds of earth-sized planets, almost identical twins of Earth. This may usher in a new era in our relationship with the universe: we will never see the night sky in the same way ever again, realizing that scientists may eventually compile an encyclopedia identifying the precise co-ordinates of perhaps hundreds of earth-like planets.
