      Size of a black hole.

      Certain mass = certain distance

      Distance = seconds

      Therefore mass = seconds

          You most certainly don’t, that’s a radius of about 300km (186 miles) and a mass of 101 suns.

          Even if you meant microsecond, that’s 1/10 of the sun, and would be very disruptive.
