Fascinating! It’s mind boggling how we owe our very existence to what’s going on 1,800 miles below our feet. It’s every bit as important to us as the Sun, because without it, we would be a ‘dead planet’ just as Mars is.
It would be awesome to see what things look like in there. I’m still trying to imagine what an Iron/Nickel ball the size of our Moon must be like. lol
It is amazing! I have heard of this too. Have you heard of the phyics/metaphysics radio show...gravitydrivenuniverse.org? It’s a great show. Different.
