I don't understand physics so this is credible to me

Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

You certainly know it, but sharing it for the ones who don't:
The full equation is
E² = (pc)² + (m₀c²)²where E, p, c, m₀ are respectively: energy, momentum, the speed of light, inertial mass. The(pc)²part is kind of a big deal, because otherwise massless particles (like photons) would have no energy.If p = 0, then the equation simplifies into that famous E=mc².
What I think is funny is that if you assumed E=mc^2 for all particles, then that would mean that red light is lighter than blue light.
This, too: if E = hc/λ and E = mc², then we can combine both as hc/λ = mc². Rearranging this shit you get m = h/λc. Since h/c = 2.2*10⁻⁴²kg*m, you'd get:
