100 yottametres
From Wikipedia, the free encyclopedia
(Redirected from 1 E26 m)
To help compare different orders of magnitude, this page lists distances greater than 100 Ym (1026 m or 11,000 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.
- 130 Ym — redshift 6.41 — 13,000 million light years — Light travel distance (LTD) to the quasar SDSS J1148+5251
- 130 Ym — redshift 1000 — 13,700 million light years — Distance (LTD) to the source of the cosmic microwave background radiation; radius of the observable universe measured as a LTD
- 260 Ym — 27,400 million light years — Diameter of the observable universe (double LTD)
- 440 Ym — 46,000 million light years — Radius of the universe measured as a comoving distance.
- 590 Ym — 62,000 million light years — Cosmological event horizon: the largest comoving distance from which light will ever reach us (the observer) at any time in the future
- >>1,000 Ym (1 kYm in older usage) — Size of universe beyond the cosmic light horizon, depending on its curvature; if it is zero (i.e. the universe is spatially flat), the value is infinite (see shape of the Universe)
This series on orders of magnitude does not have a range of longer distances.
