💡🌌 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.

If you knew anything about history of mankinds creation you would know how principalities and laws of the universe work . Love the video.
I'm 9 minutes in, and you speak as this is FACT. Nope, this is a THEORY. I can give a completely different theory about what gravity is, the limiting factor of the speed of light, and I can debunk that light is the fastest 'think' in the universe. And my explanation is far more simple, elegant, and doesn't require the fabricated math equations like Dark Matter & Dark Force.
The reason Einstein's 'theory' has basically won the hearts & minds of the science community, over say Nicola Tesla's theories, is simply because they are atheists and can't accept that there could possibly be a intelligent designer.
Space-time is simply a workaround for the atheist to deny the existence of the Aether. You see, even spell check refuses to acknowledge the word.
The reason light has a speed limit is simply because the Aether has a speed limit, All energy MUST have a 'medium' for that energy to propagate through. Sound uses air as the medium. Sound has no mass either, however, the pressure that sound creates, gives the appearance of matter. Proof: How does a microphone work. It is essentially a scale, just like your bathroom scale. The sound wave puts air under pressure, when the sound wave meets the microphone pickup.
Light is no different. Light is nothing more than a wave, it doesn't have a particle. However, the 'photon' you speak of, is simply the 'pressure' that the carrier (Aether) is applying to whatever the light wave is coming into contact with.
Gravity is not a result of 'bending space-time' or displacing space-time, Gravity is nothing more than mass. low level electromagnetivity. Proof: Electromagnets can be powered enough to build enough of a magnetic field that non ferrous items can be overcome by earths gravity.
Where does the electromagnetivity come from? The Sun, through a series of Birkland Filaments, entering and leaving through the north & south poles of earth… Basically turning the mass into a toroid. And the added benefit of this toroid is, that it acts as a cosmic radiation shield, protecting all inhabitants on earth.
Now, If that's not evidence enough to make a scientist back up to the very FIRST principle question he should ask, when observing a phenomena is "What does this observation mean if God exists", and "What does this mean, if God doesn't exist."
Once the science community accepts the above, truly new discoveries will be uncovered… in medicine, in energy conservation, in understanding how matter actually works.
I feel so strongly about what I've written here because I have invented a device that imparts a resonant frequency into ANY electrical circuit, that reduces impedance in that circuit by 12%, when measuring amperes consumed in said circuit.
Now, think about what on earth is an electrical circuit? Naturally AC or DC electricity is, But so is any living being. You, a human are largely electrical. Water (H2O) is able to form, simply because the covalent bond is an electrical circuit. And when I can reduce the resistance in water by 12%, what happens… Water turns into hydronium (H3O+, or H3O2), Dr, Gerald Pollack has discovered this phenomena and calls it 'the fourth stage of water'. Or EZ (exclusionary zone) water.
This resonant frequency treatment of water, can actually turn water into a combustible fuel, it can be used to desalinate salt water, it can slow the effects of aging. Those are just a few of the discoveries I've made, simply because I adhere to Nicola Tesla's famous quote "If you want to understand the universe, you must think in terms of energy, frequency, and vibration". Once you get that, and forget that Einstein isn't correct on much of what he theorized, you'll begin to really unlock your knowledge.
Why do they keep asking why does light travel at that exact speed, when it is us humans who determined how long a meter or any other length should be. It's not physics that determined how long a meter should be it is us humans. When a cheetah runs at full speed it doesn't know it is running 60+mph it just knows it has to move fast to catch it's food. Us humans when determining how long a meter should be could of quite easily made it twice as long or half as long. Measurements didn't exist until humans came along. Also if light was moving faster or slower they would still be asking that question, it has to move at some kind of speed.
I'm surprised you say light has no mass. This was proven wrong once it was observed that light bends near heavy celestial objects. That's why stars look in a different position sometimes when light passes near a heavy object. So what is true: no mass, or a tiny mass?
While it seems to be accepted that at velocity v=0 photons may have null mass, no one has yet managed to capture photons and slow them down to static positions.
Photons in motion have mass indeed because photons have momentum.
Photons have momentum because photons hitting things may generate work.
To generpate work mass is needed. If a particle has momentum such particle has mass.
Photon momentum : p = h/lambda
1.- While it"s accepted that photons at null speed may have null (theoretical) mass, no one has yet captured and slowed down photons to static positions.
2.- Photons have mass of 1eV/c^2 = 1.78266192e-36 kg
3.- Photons have mass because on hitting things may generate Work.
4.- Photons have mass because photons have momentum.
5.- Photon momentum = h/lambda
6.- The higher the frequency of a photon, the shorter the photon wave length of such photon is and the more energetic such photon is.
