    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.
