Abstract
IN NATURE of May 30, M. Leontovski1 shows that “To a most sensitive eye, the background of the galaxies would appear as a dark red.” Since the irresolvable background consists of nebulæ receding with nearly the speed of light, the age of these nebulæ, as observed, reckoned in our own time-scale, must be approximately one half the present age of our own surroundings; that is, if t is the conventional value of the age of the universe, ½t is the age of the observed background2. Combining these results, we see that the background realizes the poet's dream of “A rose-red city, half as old as time.”3
