빛의 속도에서는 왜 시간이 멈출까? 파인만의 충격적인 설명

If we reach the speed of light, does time really stop? We usually think of time as flowing equally for everyone. However, Einstein's Special Theory of Relativity tells a completely different story. In the universe, time and space do not exist separately. They are connected by a single spacetime structure, and the faster an object moves through space, the slower its movement in time becomes. Inspired by Richard Feynman's way of thinking, this video explores why high speeds slow down time. Why isn't the speed of light just a simple speed limit? Why can no object exceed the speed of light? And why does a photon—the particle of light—appear as if time is not flowing from its own perspective, even though it has traversed the universe for billions of years? The universe operates as if it has assigned a fixed "speed budget" to every being. The faster you travel through space, the slower time flows. This is not just a figment of imagination. Particle accelerators, spacecraft, GPS satellites, and high-energy physics experiments demonstrate that time dilation actually occurs. The time we take for granted may not be an absolute background. Time is inseparable from motion, and our intuition crumbles completely in the face of the speed of light. In Feynman's Way, we explore the deepest principles of reality through physics. #RichardFeynman #Time #SpeedOfLight #SpecialTheoryOfRelativity #Einstein #Physics #Spacetime #Photon #Universe #TheoryOfRelativity #Science #QuantumMechanics #ScienceDocumentary 📚 References Albert Einstein — Relativity: The Special and the General Theory Albert Einstein — On the Electrodynamics of Moving Bodies (1905) Richard P.
