What’s that in golf balls?

Interesting.
Good to see people questioning the absolute unquestionable foundations of physics.

OTOH if they can’t actually confirm that photons do have mass, it’s a bit inconsequential.

Ta.
Morning pilgrims, cold but fine in the pearl of the south specific.
Over.
How many golf balls does the pearl weigh?
Yeah that’s pretty small. If it were at that upper bound, all the electrons on Earth would have a mass of … about 100 tonnes?

But that’s electrons.
I don’t know how many photons there are, but presumably far fewer than the number of electrons.

Yeah I had a brain explosion.

Too many photons can do that.

more photons.
4 × 1084 vs 1081. Observable Universe.

But we are looking at the surface of a tiny little sphere, and comparing with the whole volume of that sphere.

well, that makes your estimate just as fanciful then.

My estimate of “I don’t know how many” is fanciful?

you said, presumably. So i figured you based that on some knowledge.

Wots it in TNT?
