Eli5 Why can light not carry sound?

697 views

From my very limited understanding sound is basically the vibrations in particles/atoms/ whatever, and light is some sort of weird mix between energy and very small particles, so why can light not carry sound? ( sorry if grammar/wording is bad high)

Edit: woke up to all of this, thank each and everyone of you so much!

The other answers here kind of cover it. There’s one more thing missing, though, as light is (mostly) not self-interacting.

Any change in that light will travel outwards at the speed of light. The photons don’t bounce off of one another to carry pressure waves forward. Only in the most extreme examples does light interact with itself, and the math to figure out if it could carry anything like a sound wave is beyond me.
