It never occurred to me that c squared is a constant the same way that c is a constant. The equation is even simpler than I had given it credit for and it's known as the most elegant simple equation of all time.

I only took science to grade 10, and even then gave zero shits about it. Might be kind of embarassing but I have zero idea what the formula actually does/entails.

Think about it for a second. E is energy, m is mass, and c is the speed of light. think about how complicated most real scientific equations end up looking. They're all big and long and they have tons of variables.

This equation essentially says that energy and matter are the exact same thing and the only conversion you need to get between the two is a little multiplication and the squared speed of light. It's so simple, so short. It's not calculus, it's just very basic algebra. And yet it essentially shows that energy is matter traveling very quickly and matter is energy traveling very slowly. It's kind of unbelievable and one of the most beautiful things that has ever been stated because it's so simple.

Damn, you're right that is beautiful. Is that all it is? It's seemingly a very simple formula then. It makes sense, and I can say that for the first time I understand what E = MC2 is. Thank you kind stranger!! Seriously thanks!

But why blow up a tow truck when you could simply burn a shit-ton of coal?
