    Also angles

    Would love to hear how mass is measured in seconds though

      Set G = 1 and c =1. Then equations like r = 2m make dimensional sense.

        My brother, that explanation is not nearly dumbed down enough and as with most math wiki is useless for eli5 stuff.

          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.
