Of all the material objects we know, quasars are closest…
““Of all the material objects we know, quasars are closest to lucretius's javelin. Quasars are galaxies in early stage of evolution. The light that tells us about them today has traveled for billions of years. They move away from us at a speed close to that of light; in that way they mirror the expansion of the universe.””
