The universe was born with the Big Bang as an unimaginably hot, dense point. When the universe was just 10-34 of a second or so old — that is, a hundredth of a billionth of a trillionth of a trillionth of a second in age — it experienced an incredible burst of expansion known as inflation, in which space itself expanded faster than the speed of light.
Edwin Hubble discovered this phenomenon of the expanding universe by observing a distant galaxy. He observed that the galaxy is constantly moving away from us. His discovery7 is so significant that the world's most powerful space telescope is named after him.
During this inflation period, the universe doubled in size at least 90 times, going from subatomic-sized to golf-ball-sized almost instantaneously. Before the Big bang, the universe was smaller than the size of an atom and made up entirely of energy. This energy during big bang got converted into mass which continued expanding under it's immense energy. This unlikely conversion was proved by Albert Einstein in his energy-mass conversion theory which is also the base of formation of atomic bombs.
After inflation, the growth of the universe continued, but at a slower rate. As space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos. Which are the base of almost everything we see in this world.
