Evan Skillman is an astrophysicist who studies helium abundances in dwarf galaxies to learn more about the very early universe. In the Big Bang theory, within the first three minutes, the material cools sufficiently to form the lightest elements—hydrogen, helium, and a tiny bit of lithium. All of the heavier elements are made later by stars, so the amount of helium relative to hydrogen is a prediction and therefore a strong constraint on the Big Bang theory.
