Hi, i have a question about Earth's core. How does it keep on going (endless)? i mean will it last forever, and if it doesn't what will happen when it burns out? Do the other planets in the solar system have cores?
Question 2: if we managed to get carbon dioxide to heat up mars, could it be a habitable place, like on earth?
thanks!
