9 thoughts on “ Accelerating Universe

  1. Because the matter contained in these galaxies would first have to accelerate up to speed and the seed mass located in these regions of space would also have to form to attract matter these big distances, it would take at least billion years for this all to happen.
  2. May 29,  · The discovery of the accelerating expansion of the Universe arguably provides the most profound puzzle in contemporary physics. It implies that either the Universe is dominated by a component, dubbed “Dark Energy”, that turns gravity's pull into a push, or that General Relativity, our understanding of gravity itself, breaks down on cosmological scales.
  3. Nobel laureate Adam Riess walks you through his team’s incredible discovery of dark energy and our accelerating universe. Explore one of the biggest mysteries in modern cosmology. This lecture was filmed on May 30, at the World Science Festival in New York City.
  4. Sep 13,  · Spiral galaxy NGC observed from Chile in —a new method gauges how to measure the universe's accelerating growth Scientists have .
  5. Oct 24,  · Back in , three astronomers were awarded the Nobel Prize in Physics for their discovery that the Universe wasn't just expanding - it was expanding at an accelerating rate.. The discovery led to the widespread acceptance of the idea that our Universe is dominated by a mysterious force called dark energy, and altered the standard model of cosmology forever.
  6. So the graph showed the rate of the Universe’s expansion over time.) What did the analysis of the data show? (Answer: It showed that for the first 8 billion years of its history, the Universe expanded as expected and then began to slow down. But about 5 billion years ago the expansion rate began to accelerate.) Wrap-Up.
  7. One of the most important recent discoveries in cosmology--and science in general--is that the expansion rate of the universe is not staying steady or getting slower, as most scientists had assumed; on the contrary, it is accelerating/5(15).
  8. The more shallow the curve, the faster the rate of expansion. The curve changes noticeably about billion years ago, when objects in the universe began flying apart as a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart.
  9. Apr 26,  · The universe is expanding – this we know from looking at red shifts of distant galaxies – but the acceleration of the universe's expansion is harder to measure.
