Anyone who knows me knows I’m horrible at time management. I haven’t researched as much as I had hoped for my topic with other homework and softball picking up. But thank Higgs boson spring break is next week! Prepare yourself for learning!
So I guess comic books get their physics right! The comics say that Superman has his super-strength because Krypton’s gravity is much stronger- 15x stronger- than Earth’s gravity. In order for Krypton to be small enough (so it’s not a gas planet) while still having this gravity and not introducing any new forms of matter, Krypton’s center would have to be a neutron star (the extremely dense remnants of a supernova). And the gravitational strain from the center would cause violent phenomenons on the surface, creating the catastrophe causing Superman’s parents to send him to Earth!
