Currently Playing: Why Does Motion Slow Time?

Thanks to ChatLLM by Abacus AI for sponsoring this video. Explore leading AI models and tools in one place for $10/month: https://chatllm.abacus.ai/phy What if the shortest path through spacetime is actually the one along which the greatest amount of time passes? In this video, we take a deep dive into Einstein's Special Theory of Relativity, exploring how space and time are connected, why moving clocks experience time differently, and what the famous twin paradox reveals about the geometry of spacetime itself. Starting with Einstein's revolutionary ideas, we'll build towards one of the most remarkable consequences of special relativity: the straight, inertial path between two events in flat spacetime is the one along which the greatest amount of proper time elapses. Along the way, we'll explore time dilation, spacetime intervals, light cones and proper time, laying the foundations for our next journey into Einstein's General Theory of Relativity. 🤝 Support the channel Patreon → https://www.patreon.com/physicsexplained 🔗 Follow me Instagram → https://www.instagram.com/physics_explained_ig X (Twitter) → https://twitter.com/PhysicsExplain1
