        My understanding is that was the ‘fear’ if certain parts of string theory were right and had certain parameters, but it didn’t happen (ruling those out)

        We are not there yet. Some of the theories put the energy requirements within reach of the LHC. They were at the extremes of possibilities however, and none have been detected so far.

      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 an object is smaller than their its 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.

    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.
