Making Matter

By lighting a fire, humans can turn matter (the object that is burning) into energy (the fire/heat). Can humans turn energy into matter?

Why It Matters

  • You can’t make something out of nothing, so you can’t make matter out of nothing.
  • Albert Einstein theorized that matter and energy are interchangeable.
  • When matter (protons) break apart in the Large Hadron Collider, they become smaller bits of matter (the subatomic particles quarks and gluons).
  • A photon is a particle of light; light is energy.
