💡🌌 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.

That bullet at the beginning of your creation; will most likely keep flying at its initial speed for a while if there is no evident force acting upon it, and the light is no different. But after a while, the distance between the gun and the bullet will grow faster than the speed of light… as my universe expands. From that moment on, the shooter can no longer see the bullet because he/she has too much mass to go after it with his meter. The bullet, however, will not lose all its mass simply by not observing it, while the light even knows in advance about your curiosity and changes its behaviour accordingly.
Those who understand a few words of Hebrew, know that God created the sky with birds in it to look at, not the light… and certainly not when it's moving away.

I am an Architect in western Massachusetts and listened to this in the early evening while working from home. You repeatedly refer to the speed of light being a speed "limit" which we measure by an arbitrary unit of measure that we have contrived here on Earth (mph, meters per second, etc.). Should we think of it as a "limit" or really just the nature of the structure of the Universe?
Man claims to have the ABILITY TO UNDERSTAND ALL THINGS. He is deceived. 1 Corinthians 8:2; 13:9. Deuteronomy 29:29. Revelation 3:17,14-22.

Light has energy and energy is effectively its mass by E equals m•c^2. Stupid Google You Tube doesn’t allow typing E equals sign without adding in little (lowercase) e.
AI can’t read equations properly. Nobody bothers to proofread and correct.
I love these AI-narrated stories. Well done, AI! lol
