#PhysicsQuestion: in "A Brief History of Time," Hawking describes how matter particles emit force particles, the recoil changing their directory and the impact changing their target's. This makes sense for repulsive forces, but how does that translate to attractive forces?

Which physical constant is the most fine-tuned for our existence?

(in the sense that by changing it a small amount would prevent the existence of (intelligent/advanced/eucaryotic/whatever) life, but otherwise leave the universe mostly unchanged)

Is there a substance that's harmful to metal but not to people or animals? Google is failing me.

it's really cold in the PNW so indoor heated air is *REALLY* dry. I have a couple of those #ultrasonic #humidifier mist #diffuser thingies but stopped using them after I heard they put dangerous micro mineral particles in the air.

Does anyone know if this #danger is real? I understand the EPA hasn't said they're unsafe, but, y'know.

The red we can see - is that Rayleigh scattering? #rayleighscattering #Astrodon #sciencequestion
