A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
If it doesn't reflect light, it'd be black. If it emitted its own light then there wouldn't be shadows in the craters of the moon and we also wouldn't have moon phases. It's hard to tell if this person is actually being serious because this is literally just entry level physics. Plus, we've collected moon rocks during the numerous moon landings.
Everybody wants a rock…
I mean, what else are you gonna wind a piece of string around?
If rocks emit their own light, how come you can land on them?
If you can see it, it's reflecting light
I think the nutcake / troll was trying to convey that the rock is emitting light. Which is no less stone bonkers and a load of old cobblers, but here we are.
