        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.
