The deeper we look into the universe, the more galaxies we see. A 2016 study estimated that the distance the observable universe travels from Earth to the edge of the observable universe is about 14.26 gigapascals (46.5 billion light-years or 4.40×1026 m) in any direction. Thus, the observable universe is a sphere about 28.5 gigapascals (93 billion light-years or 8.8 x 1026 meters) in diameter. https://en.wikipedia.org › Wiki › Observable_universe
