Revolution in Cosmology Resolves Dispute over Universes Age Essay

Revolution in Cosmology Resolves feud over Universes AgeJust under seven years ago, astronomers employ the Hubble space telescope presented results they hoped would help answer nonpareil and only(a) of the most agonistical issues in astronomy of the 20th century the question of the distance crustal plate of the creative activity. But there was some unease when the result was announced. According to the report, different galaxies were close enough that, extrapolating backwards from their current rate of recession and make adjustments for the influence of gravity, they all would make water been together (that is, the Big Bang would have occurred) as recently as 8 billion years ago. Unfortunately, there was strong evidence already in place that some stars were at least 12-15 billion years old apparently predating the origin of the creative activity itselfWhile these two highly irreconcilable values for the universes senesce for certain posed a serious challenge to astron omers, most simply pretended that better measurements would place the distance scale back in grapevine with the older age. What no one expected is that re dissolvent to this problem would untruth not in corrected measurements but a revolution in cosmology, and the apparent discovery of what amounts to a mysterious new essence of the creative activity a fifth element that hides in vacuum and drives the expansion of the universe.The scientific study of the age and origin of the universe is intimately linked with the measurements of extragalactic distance, and consequently the science did not even exist until measurement techniques dead-on(prenominal) to such scales were invented. Distance measurement has always been difficult for astronomers until the 1800s, no one knew even the distance to the nearest star (other than the Sun), and th... ...pressure and a whole host of other strange properties that gravitationally repel all surrounding space, increaseing the universe in abs ence of any physical substance. Furthermore, by expanding the universe, more drop off space is created, creating even more antigravitational force and making the universe expand ever faster, leading to a runaway expansion that will ultimately culminate in the dilution of all remaining matter into nothingness.And in this lies the solution to the long-standing age issue. If the universes expansion is constantly getting faster, it must have been laggard in the past, pushing the age of the universe upward to around 13 billion years, right in line with the ages of stars. So without any study revision to the distance to nearby galaxies or the ages of stars, the question of the true age of the universe has been solved in a way no one expected.
