I’m not really sure how diamonds are made on earth, either. I know it’s something to do with the pressure of the earth compressing them over a long long period of time, but by that rough logic, how could they be formed in space? For example i read that It LITERALLY rains diamonds on Saturn and Jupiter, and there’s been evidence of small meteors crashing into earth and leaving discards of diamonds everywhere, from space.
In: Geology
To make a diamond you need carbon, heat, and pressure.
There’s enough pressure deep inside the earth to do this over time, but the intense conditions inside gas giants and collapsing stars can forge diamonds much faster.
There’s 200,000 atmospheres of pressure at 200C in Earth’s upper mantle. It’s 10,000C and over a million atmospheres when you get down towards where Jupiter starts looking like a solid.
