In an expanding universe, the farther something is away from you, the faster it is receding. Observations from the Hubble Space Telescope suggest the universe is expanding 9 percent faster than previously thought, deepening longstanding cosmic mystery. And new physics may be required to understand why.

Although no object ever moves through the fabric of space itself faster than the speed of light, there is no speed limit on the expansion of the fabric itself; it simply does as the Universe dictates. The universe is expanding 9% faster than scientists expected, according to a new study. The universe is expanding 9% faster than scientists expected, according to a new study. And that’s sending a shudder through the world of physics, making astronomers re-think some of their most basic concepts. Picture 100 Mly of space the size of a beach-ball. The number indicates that the universe is expanding at a 9% faster rate than the prediction of 67 kilometers (41.6 miles) per second per megaparsec, which … At greater distances and earlier times in the Universe, it was expanding more rapidly. Relative to our location, nothing moves faster than light, and that's true in every location in the Universe at all times. Wait a million years. The universe is expanding faster than anyone had previously measured or calculated from theory. Hubble’s constant tells by how much. 2020, CC BY-SA 3.0 IGO And earlier this year, NASA and ESA scientists found that the Universe could be expanding around 8 percent faster than originally thought. Like Magic Marker dots on an expanding balloon, galaxies were being carried along by the expansion of space-time itself. Explaining a discrepancy between what was happening 13 billion years ago and now may require new physics. How fast is the universe expanding? The universe is getting bigger every second — but how fast? The universe is expanding faster than anyone had previously measured or calculated from theory. Although no object ever moves through the fabric of space itself faster than the speed of light, there is no speed limit on the expansion of the fabric itself; it simply does as the Universe dictates. Hubble’s constant tells by how much. Astronomers using NASA's Hubble Space Telescope say they have crossed an important threshold in revealing a discrepancy between the two key techniques for measuring the universe's expansion rate. An all-sky map showing what may be a change in the expansion rate of the Universe across the sky; faster in some places (red-yellow) and slower in others (purple-black).

But new X-ray observations now suggest that this may not be the case after all – certain areas may be expanding faster than others. The Universe is expanding, but how quickly is it expanding? Credit: K. Migkas et al. And earlier this year, NASA and ESA scientists found that the Universe could be expanding around 8 percent faster than originally thought. The discrepancy between how fast the universe seems to be expanding and how fast we expect it to expand is one of cosmology’s most stubbornly persistent anomalies.. Cosmologists base their expectation of the expansion rate — a rate known as the Hubble constant — on measurements of radiation emitted shortly after the Big Bang. The other is a prediction based on the physics of the early universe and on measurements of how fast it ought to be expanding. And new physics may be required to understand why. By all accounts, the discovery was a solid one (Nobel Prize solid) but it posed a very difficult question - if the collective gravity from all the matter expelled into the Universe by the Big Bang has been slowing everything down, how can it be accelerating? WASHINGTON (AP) — The universe is expanding faster than it used to, meaning it’s about a billion years younger than we thought, a new study by a Nobel Prize winner says. The universe is expanding faster than we thought, and no one knows why.
