1 E25 m
From Free net encyclopedia
To help compare different orders of magnitude, this page lists distances starting at 1025 m (10 Ym or 1,100 million light years). At this scale, expansion of the universe becomes significant. Distance of these objects are derived from their measured redshifts, which depends on the cosmological models used.
- 1.8Template:E m — redshift 0.16 — 1,900 million light years — Distance to the quasar 3C273 (light travel distance)
- 3.3Template:E m — 3,500 million light years — Maximum distance of the 2dF Galaxy Redshift Survey (light travel distance)
- 7.5Template:E m — redshift 0.95 — 8,000 million light years — Approximate distance to the supernova SN 2002dd in the Hubble Deep Field North (light travel distance)
- 8.5Template:E m — redshift 1.6 — 9,000 million light years — Approximate distance to the gamma ray burst GRB 990123 (light travel distance)
