Physics of the Impossible

Buchzusammenfassung

Michio Kaku, co-founder of the string field theory and professor of theoretical physics at the City University of New York, is the author of a number of best-selling books, including Hyperspace and Physics of the Impossible. In addition, he also hosts the Science Channel’s Sci Fi Science: Physics of the Impossible along with two radio programs, Explorations in Science and Science Fantastic.

Einstein's quest for a unified theory remains unfulfilled, but advancements in quantum physics and space exploration bring us closer to this goal, with technologies like radiation-detecting satellites and string theory offering promising insights. While weaponized lasers, such as handheld phasers, may soon become feasible through nanotechnology, planet-destroying super-lasers remain improbable due to immense energy requirements. Theoretical faster-than-light travel, via space bending or wormholes, faces significant hurdles like negative energy and radiation exposure. Quantum teleportation and entanglement hint at future possibilities for instantaneous travel, though human teleportation is far from achievable. Time travel, while theoretically possible, is constrained by paradoxes and technological limitations, with parallel universes offering a potential resolution. Artificial intelligence progresses through experiential learning, enabling robots to assist in missions like those on Mars, though true comprehension and common sense remain elusive. Mind-reading technologies, though advancing, are limited by the brain's complexity, while biofeedback innovations allow paralyzed individuals to control devices, hinting at future breakthroughs. Perpetual motion machines defy thermodynamics but inspire research into dark energy, which remains poorly understood. Force fields, grounded in classical physics, are being explored through plasma and metamaterials, potentially enabling rocket-deflecting shields and invisibility. The search for extraterrestrial life intensifies with improved telescopes and targeted criteria like water and planetary stability, though definitive evidence remains elusive. To ensure humanity's survival beyond Earth's eventual destruction, scientists are developing propulsion technologies like ion engines, plasma engines, and ramjet fusion rockets, alongside addressing challenges like radiation and weightlessness, paving the way for interstellar travel.
