      I think a lot of people understand the concept of light-seconds, which can measure distance in seconds.

      Allow me to introduce the gravity-second. 1 gravity-second of mass-energy is enough mass-energy to have a Schwarzchild radius of 2 light-seconds.

          Size of a black hole.

          Certain mass = certain distance

          Distance = seconds

          Therefore mass = seconds

            Then I don’t even want to be in same solar system with millisecond heavy object.

              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.
