S. Light

 Alright, slower and clearer — here’s the plain-English explanation 👇

The core idea is this:

Light exists because of how matter is allowed to behave.

Step by step

1. Matter has charged particles
   Electrons and other particles carry electric charge.
2. Charged particles can’t just sit perfectly still
   When they move, accelerate, or change energy levels, physics forces something to happen.
3. That “something” is light
   Any change in a charged particle creates disturbances in the electromagnetic field.
   Those disturbances are photons (light).
4. So once you allow:
   
• particles
• charge
• motion
• energy changes
5. 
   → light is unavoidable
6. No special tuning required
   The universe didn’t need an extra rule saying “and now add light.”
   Light automatically falls out of the equations.

Big takeaway

A dark universe isn’t the default that somehow got lucky and became bright.

Brightness is the default.

To not have light, the universe would need:

• no charged particles, or
• no energy changes, or
• completely different physical laws

Which would be a radically different universe — not just ours with the lights turned off.

If you want, I can explain this with:

• a metaphor
• zero math
• or why this matters philosophically
