I remember reading most of Arthus C Clarkes books. Being extremely fasinated by both the Rama series, and of course the 2001 series. During one of theese i remember we visit Jupiter and it’s speculated that because of the massive pressure of the planet, and the planet being mostly gas in the outer layers even life exists there. Airborne creatues of various degress living in hazzardous inviroments were they can only survive on a specific layer of height above the “surface”.
Now the interesting part was that the core of the planet due to the massive pressure would actually be a gigantic diamond never to be seen because of the pressure sourrounding it.
Anyhow a new article it seems we wont be finding a diamond could be somehow visit the core of such a planet. Interesting read 😉
