Is Time Travel Really Possible
Close your eyes and let your mind drift into the quiet mystery of time travel. A gentle journey through the science of what is possible and what may never be. Traveling to the future is real—Einstein proved that time slows down with speed and gravity, a phenomenon confirmed by astronauts. But traveling to the past remains forbidden by physics. Wormholes exist only in math, and Stephen Hawking's Chronology Protection Conjecture suggests the universe will always prevent backward time travel. Let the quiet wonder of this mystery carry you into a deep and restful sleep.
