>So, is light not really massless?
yes

Oh my God. I can easily see this is a troll, and yet I still raged at the lack of algebra.

Lack of algebra? a=bc therefore b=a/c

Seems right to me.

>>4240656

What lack of algebra?
<div class="math">E=mc^2[/moot]
<div class="math">\frac{E}{c^2}=m[/moot]

Also, mass is related to inertia. While in motion, photons have infinite mass.

a^2 + b^2 = c^2

E = mc^2

therefore, E = m(a^2 + b^2)

reported for underage. come back when you learn about debroglie

>>4240674

Jesus, what?

a / b * a != a
8 / 4 * 8 != 4

>batman?

It should be m=(c^2)/E.

2.2 * hadoy = 16/22 alien log^3

0/10

The full equation is E^2 = p^2 c^2 + m^4 c^2

Simplified, wave particle duality says waves, like light or any other electromagnetic radiation, behave as waves in a vacuum but as particles when encountering matter. Einstein built on Max Planck's work to theorize that light was made of little packages basically, that he called photons. So yes in theory light or any other energy has an infinitesimally small amount of mass. This is an important part of quantum mechanics.
