Answer» Further, space is a vacuum, meaning that sound cannot carry because molecules are not close enough together to transmit sound between them. That's not to say that space is EMPTY, however. Gas, dust and other bits of matter float around "emptier" areas of the universe, while more CROWDED regions can host planets, stars and galaxies. No one knows EXACTLY how big space is. The difficulty arises because of what we can see in our detectors. We MEASURE long distances in space in "light-years," representing the distance it TAKES for light to travel in a year (roughly 5.8 trillion miles, or 9.3 trillion kilometers). 凸(-_-)凸凸(-_-)凸凸(-_-)凸凸(-_-)凸凸(-_-)凸 ╭∩╮╭∩╮╭∩╮╭∩╮╭∩╮╭∩╮╭∩╮╭∩╮
