Define "thing" and define "heavy"
A super cluster of galaxies is probably the heaviest "thing" if you consider such a widely distributed thing a "thing." Otherwise supermassive black holes are the densest "things" we know, though the may not be the "heaviest"
EDIT: The Universe is the heaviest...
Hi 0xDEADBEEF if # of photons depends on Amplitude, and if Amplitude comes from Intensity, since these two beams have the same intensity, they will have the same Amplitude, and thus the same # of photons?? (Obviously this isn't the case.)
"amplitude" is what is throwing me off here...
Hi Let's stick to the classical limit.
We have 2 monochromatic light waves of same intensity. Let's say one is blue and one is red.
Now this means the individual photons of the blue light have more energy(obviously, higher frequency) and the red light photons have lower energy. But since...
