The Diamond to Graphite Process

Your expensive diamond is literally turning into pencil lead right now. Thermodynamics proves

that graphite is actually more stable than diamond, so the universe is constantly trying

to switch it back. This is what we call a spontaneous process, meaning it happens

naturally without any outside help. But don't panic, spontaneous doesn't mean fast,

so your ring is safe for a few million years. It all comes down to Entropy.

Basically, the universe is obsessed with being messy and chaotic. It is why ice melts

into water and why your room gets messy on its own. Nature just wants to be disorganized.
