Many flat earth advocates mention that the moon emits its own light because rocks “don’t reflect light”. I’ve done an experiment.
Here’s a decent rock. Not black, not white, just a reasonable gray.
The experiment setup: a white melamin board as screen, the rock, and a laser pen at right directed at about 45 degree on the rock.
We don’t see much reflection on this picture, since the flash was used.
Now, without flash, we clearly see a diffused reflection.
So the moon reflecting the sunlight is plausible.
