    i was just wondering if theres anything smaller than a quark because as far as i know up, down, anti-, etc. quarks make up the universe.

    I believe the Standard Model currently treats both quarks and leptons as pointlike.

    This should be moved to the Particles section.

    An electron is a fundamental particle. There are no quarks associated. At least, that's my understanding.
