No one really knows what happens inside an atom. But two competing groups of scientists think they've figured it out. And both are racing to prove that their own vision is correct. Here's what we know ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom’s central core and contains more than 99.9 ...
