Using information gathered from 140 thousand different quasars and intergalactic hydrogen, scientists claim to have made the most precise measurements of how fast the early Universe was expanding over long stretches of time. According to data from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey, the Universe started expanding rapidly after the Big Bang happened an estimated 13 point 8 billion years ago.
