How can the universe expand faster than light
WebAnswer (1 of 102): The universe is not “expanding faster than light speed”. The expansion has no speed. The present-day rate of expansion is approximately 70 km/s/Mpc (Mpc = megaparsec, about 3.26 million light years.) You can derive a speed from this rate, but only once you know the distance b...

This is a ground-based telescope's view of the Large Magellanic Cloud, a satellite galaxy of our Milky Way. The inset image, taken by the Hubble Space Telescope, reveals one of many star clusters scattered throughout the dwarf galaxy.
WebAnswer from John Mather. Web9 de fev. de 2024 · The expansion of the universe is not resulting in matter moving faster than the speed of light, only that the "edge" of the universe is travelling outward at a rate great than c. The expansion of the universe does not mean that matter is being moved at a speed greater than c, but only that space is being created at a rate that is greater than …
Web3 de fev. de 2024 · Cosmic expansion rate between two points is a factor of distance, and two observers with no relative velocity measure the same distance. Likewise, they will never see you see the other object's event.
