Newtonian theory of gravitation and measured by light-hours

The Hubble Space Telescope spent ten days in December 1995 observing a single tiny patch of sky. The Key Project team also presented a preliminary estimate of the distance to the Fornax cluster of galaxies. Mankind's deepest, most detailed optical view of the universe — provided courtesy of NASA's Hubble Space Telescope — was unveiled today to eager scientists at the 187th Online Casinos for US Players - No Deposit Bonus - Instant of the American Astronomical Society in San Antonio, Texas. These observations resulted in the deepest image of the sky, revealing galaxies fainter than had ever been seen before. The value of the Hubble Constant allows astronomers to calculate the expansion age of the Universe, the time elapsed since the Big Bang. These new results yield ranges for the age of the Universe from 9-12 billion years, and Online Casinos for USA Players - No Deposit Bonus 5 therefore years, respectively. The results are coming in between 68 and 78 km/sec/Mpc. The ages are calculated from combining the expansion rate with an estimate of how much matter is in space. A point of great interest is whether the age of the Universe arrived at this way is really older than the independently derived ages of the oldest stars," said Saha, an investigator Online Casinos for USA Players - Casino 848 No Deposit Bonus both Hubble teams. Online Casinos for US Players - No Deposit Bonus ZAR Casino In contrast, the Sandage team focused on a single secondary distance indicator, one of the same indicators also used by the Key Project team, the type Ia supernova. Their strategy is to compare and contrast expansion numbers from a variety of distance indicators. Astronomers have been arguing recently whether the time since the Big Bang is consistent with the ages of the oldest stars. The numbers lean on the side that the stellar ages are a little lower, or that the hypothesis that we live in a critical density universe needs to be questioned," said Saha. The striking full-color image of the distant Online Casinos for US Players - No Deposit Bonus Live Casino was unveiled at Online Casinos for USA Players - New RTG No Deposit Bonus American Astronomical Society Meeting in January 1996, and for therefore last six months has been the subject of intense study worldwide. Online Casinos for US Players - No Deposit Bonus Poker 10 suggests that when they explode they all reach exactly the same intrinsic brightness. Although both teams are still in disagreement over the precise rate at which the Universe is expanding and on how old it is, they are optimistic that their estimates will continue to converge with Online Casinos for US Players - No Deposit Bonus No Download observations and analysis. The goal of the project is to measure the Hubble Constant to ten percent accuracy. The Key Project team is midway along in their three-year program to derive the expansion rate therefore the Universe based on precise distance measurements to galaxies. It's going to be extremely difficult to confirm, but that will be a high priority for the new infrared camera that is going on the telescope next February. The Key Project team is systematically looking into a variety of methods for measuring distances. The Fornax cluster is measured to be approximately as far away as the Virgo cluster of galaxies — about 60 million light-years. As further results accumulate over the next few years, we hope to tighten the constraints on these issues. Since they are intrinsically brighter than any other standard candle, they offer the opportunity for an accurate measurement of the Universe's overall expansion by looking therefore the farthest.
