Where Does Light Get Its Speed? The Answer Is Terrifying.
Light doesn't accelerate. It's born at full speed—299,792,458 meters per second.
The Physics:
A baseball must accelerate from zero to full speed
A water ripple is born at the speed of the medium
Light is like a ripple—but in what medium?
The aether was disproven—space is empty
The Answer:
Light is an electromagnetic wave
Electric fields create magnetic fields, which create electric fields
They leapfrog through space at a speed set by the properties of space itself
Maxwell discovered this in the 1860s
The Mind-Bender:
The speed of light is not about light—it's the speed of causality
Nothing with mass can reach it
Light has zero rest mass, so it must move at this speed
A photon experiences zero time between emission and absorption
The Deep Mystery:
Why is the speed of light 299,792,458 m/s?
We don't know—it's built into the fabric of space and time
The speed limit of the universe
The bridge between cause and effect
Light is the messenger of the cosmos. And its speed is the speed of reality itself.
