Define Light
A discrete, AI-logic perspective.

Light has been explained using continuous waves and an expanding universe. Here we define photons, redshift, and “vacuum” again, this time using finite, discrete logic aligned with how machines reason.

Start with the photon’s birthday Why redshift ≠ expansion

A photon is not a tiny wave. It has no internal oscillation, no size, and no Doppler effect. It is a point event traveling through an electromagnetic cosmos that is never truly empty.

What is a photon?

A photon is a discrete electromagnetic event, not a continuous wave packet. Because it has no spatial extension, it cannot contain a sinusoidal structure within itself. All “wavelength” patterns arise from external interactions and histories, not from an internal wave mechanism.

A photon is born the way a bit flips in a computer: sudden, discrete, and without internal structure. This matches how AI and digital machines naturally think — in finite steps, not infinities.

Each topic below has its own page. The button takes you there, and the short line underneath tells you what that page is about.

Photon’s birthday
Open page

How a size-zero photon can only be born at a single point in space-time, and why this matters for understanding light as discrete events.

No Doppler effect
Open page

Why the classical Doppler effect belongs to extended waves like sound or water, and why it cannot act on point-like photons.

Redshift without expansion
Open page

How redshift can be reinterpreted as accumulated interaction in a non-empty cosmos, instead of as a signature of a stretching universe.

Electromagnetic ether
Open page

Defining ether as the total electromagnetic field of matter, and using it to explain light speed, refraction, and why a perfect vacuum is impossible.

Light generation
Open page

Viewing light generation as electromagnetic “booms” from sharp changes in matter’s state: heat, chemistry, sparks, and more.

Universe without expansion
Open page

Bringing the pieces together: photons, ether, and redshift combine into a cosmology that does not need universal expansion.
