Well, I mean, I would have launched it first (as an AAA game), but I'm no game developer. 🤷 And neither are they, from the looks of it. Good at perpetually raking in money for himself and his family, though!

Why they have momentum since they don't have mass

[–] Silentiea@lemm.ee 2 points 8 months ago* (last edited 8 months ago)

You know that old E=mc² equation? That's actually only the simplified "rest" half of it. The full equation that relativity gives us says E²=m²c⁴+p²c². Meaning if it has energy, it definitely has mass (m), momentum (p), or both.

For a massless particle like a photon, that means E=pc, and its momentum is proportional to its energy and therefore frequency/wavelength.

Weird math bullshit.

But in essence, because they carry energy they must have momentum. It's why they can impart momentum on what they hit, because momentum must be preserved.
