Signature

He was the first person to say the Universe is growing. Some people think it was Edwin Hubble, but that is not correct.^[1][2] Lemaître was also the first to make the Hubble's law and the Hubble constant.^[3][4][5][6] Lemaître also started what became known as the Big Bang theory of the origin of the Universe. He called it his 'hypothesis of the primeval atom'.^[7][8]
