    Physicist & astronomer Georges Lemaître was born #OTD in 1894.

    In 1927 he proposed a model of an expanding Universe. Then, in 1931, he ran the clock backwards and hypothesized its origin as a “unique atom” or “unique quantum,” paving the way for modern ideas about the Big Bang.

    Lemaître and the expanding universe were the subject of a nifty Google doodle back in 2018.
