WOH G64 (For comparison) 1,540 [c] ± 77 [9] L/T eff: Located in the Large Magellanic Cloud. Possibly the largest known star. [9] [10] [14] [11] Theoretical limit of star size (Milky Way) ~ 1,500 [15] or ~1,800 [16] Lower value comes from the rough average radii of the three largest stars studied in the paper.
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [ 1] It was first proposed as a physical theory in 1931 by Roman Catholic priest and physicist Georges Lemaître when he suggested the universe emerged from a "primeval atom".
