WebbWe'll then have a mess of quarks -- the type of quarks called "up" and "down," which have certain masses and are the only kinds found in matter on Earth. Squishing even more, we'll stress the up and down quarks so much that some change their identities. Some will get a lot heavier and become strange quarks. Our familiar iron atom will be long gone.
