In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about five-and-a-half billion light-years away.

      I would be willing to use grams in this case. Final offer.

        The sun itself is already 1.988 kQg (kiloquettagrams), having maxed out the SI prefixes. 36 billion suns would be 71.64 TQg (teraquettagrams).

    How large would the event horizon of such a black hole be?

      I just hopped on this calculator and it says about 710.9 AU, or 106,348,555,982 km (66,081,929,023 miles). So pretty big.

        Oh my word. 30 AU is roughly the distance to Neptune, so this black hole is almost 24x the diameter of our solar system.

        Pretty big, yeah.

          What’s the distance to Proxima Centauri?

          Edit: It’s 268553 AU.

            Is this what we do now that Google sucks, just ask each other what Wikipedia says?

            It’s uh, 4.2465 ± 0.0003 light years by the way.
