    Why isn’t it called “cold matter”?

    Don’t we just not see it because it’s not burning?

    Couldn’t the unseen mass be clouds, planets and black wholes?

      No, because those would also interact with other things like electromagnetic radiation, light, etc. Dark matter only interacts with normal matter via gravity.

      Dark matter is admittedly a bit of a misnomer but that’s what everyone’s been using for years 🤷🏻‍♂️
