Could hard light shone onto an asteroid slow it down or alter its course?

Hard light or solid light is largely a sci-fi/video game concept at this stage. Wikipedia says:

>It has been theorized that solid light could exist. Some experiments claim to have created solid photonic matter or molecules by inducing strong interaction between photons.

Potential applications of solid light could include logic gates for quantum computers and room-temperature superconductor development.

A team of Italian scientists published in Nature Journal in March 2025 that they have found a way to make light act like a “supersolid”.

Solid Light

…but whether these ideas have any application to slowing down asteroids, I have no idea.

yes

Would that mean hard light had mass if it could push something

no, it has momentum.

no, it has momentum.

Momentum = mass x velocity.
