💡🌌 Light Has No Mass… So Why Is Its Speed Limited? | SLEEP SCIENCE STORIES
Light is massless, yet it travels at a fixed speed—299,792 km per second. But why can’t it go any faster? In this sleep science story, we’ll unravel one of physics’ greatest mysteries: why the universe has set a cosmic speed limit, even for something as weightless as light.
In this calming yet mind-bending journey, you’ll discover:
✨ How Einstein’s theory of relativity explains the speed of light
⚛️ Why light’s masslessness doesn’t mean infinite speed
🌌 How spacetime itself enforces this universal law
💫 What it means for time, causality, and the limits of the cosmos
Perfect for relaxing, unwinding, and drifting off to sleep, this story blends soothing narration with profound science, letting your mind travel at the speed of imagination.
