Explanation:
Detailed explanation-1: -It turns out that space is expanding pretty slowly: at present, cosmic distances increase by just 0.007% in one million years.
Detailed explanation-2: -Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. One explanation for dark energy is that it is a property of space.
Detailed explanation-3: -The new study confirms previous expansion rate estimates based on Hubble observations, showing an expansion of roughly 45 miles (73 kilometers) per megaparsec. (A megaparsec is a measurement of distance equal to one million parsecs, or 3.26 million light-years.)
