    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.

      I get what you’re saying but am still too dumb to understand it lol

        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.
