Because of mass. But WHAT is mass?

• drsnow 4y ago
  A measure of a particle's energy as pertains to the spacetime curvature it induces

    This is incorrect all the energy of a particle curves space. Even velocity and potential energy.
    • drsnow 3y ago
      Right, so those kinds of energy also induce spacetime curvature and are included in what I was saying

  Wikipedia says “the property of "mass" is a manifestation of potential energy transferred to fundamental particles when they interact ("couple") with the Higgs field, which had contained that mass in the form of energy.”

  Energy, not mass. Photons also curve space in this way. Mass is just one kind of energy.
