    TIL. Didn’t consider black holes could be that small.

      Technically all objects have an event horizon, the special feature of black holes is just that they are actually smaller than their event horizon

        Every object has a Schwarzschild radius, but only if objects are smaller than their own Schwarzschild radius (black holes) it defines an event horizon, i.e. by all means of physics, we cannot “see” what is going on inside.

      They supposedly make microscopic ones all the time in particle colliders, but they dissipate almost immediately.

    The full video isn’t much longer and has a few more jokes.

    Wouldn’t that ruin the Earth’s tidal system and like destroy life on earth? Idk

      Actually…

      No. The mass doesn’t change. And a uniform sphere at distance is identical to a point as far as gravity is concerned.
