1 E26 m
To help compare different orders of magnitude, this page lists distances greater than 1026 m (11,000 million light years). At this scale, the expansion of the universe becomes significant.
- Distances shorter than 1026 m
- 1.3 × 1026 m — 13,700 million light years — Distance to the cosmic background radiation; radius of the observable universe.
- 2.6 × 1026 m — 27,400 million light years — Diameter of the observable universe; light travel distances greater than this are currently physically meaningless.
- 5.9 × 1026 m — 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.
- >> 1027 m to infinity — Diameter of the whole universe.
