Hi, All.
Could someone please answer a couple of dumb questions from someone who is simply interested in this topic?
Is it a fact that the earth's core is iron?
Has it ever been postulated that the earth's core contains a tiny massively compressed particle that "generates" gravity?
Many thanks, from just another "ever curious soul."
