Hi everyone, first time poster. Considering some of the things discussed here, I apologize if my question sounds simplistic. If this earth could be compressed so that all the empty space in atoms would disappear how big would this earth be? My science teacher once told me that it would be the size of a marble, and I've also heard that it would be the size of a large stadium. I realize it's not an easy thing to estimate but that seems to be quite a difference. An example of such scales of atoms would be appreciated. (i.e. I've also been told all 6.5 people in this world could be compressed into the size of a kidney bean) Thanks!
