Why Space and Time Are Secretly One Thing | Physics By Night

Welcome to Physics By Night, a calm science channel for sleep, relaxation, and quiet curiosity under the stars. In this peaceful journey, we explore why space and time are secretly one thing. From Newton’s comfortable universe of absolute space and universal time, to Maxwell’s light, Einstein’s special relativity, Minkowski’s spacetime, curved gravity, black holes, gravitational waves, and the expanding universe, this video gently reveals how modern physics changed our understanding of reality. Space tells us where. Time tells us when. But relativity shows that every event has both — and that space and time are woven together into something deeper: spacetime. If this quiet physics story helps you relax, learn, or fall asleep, a gentle like and subscribe helps the channel grow. Tell me where you’re listening from, and what time it is there. #Spacetime #Relativity #SleepyScience #PhysicsForSleep #PhysicsByNight
