BEACON TRANSCRIPT – The Universe is expanding rapidly than believed, researchers say. The National Aeronautics and Space Administration along with the European Space Agency have recently announced that the Universe is expanding up to 9 percent faster than previously thought.
A research team from the Space Telescope Science Institute and Johns Hopkins University has developed a new and more accurate technique to measure the continuously increasing size of the cosmos. The new techniques measure stars and supernovae; about 2,400 Cepheid stars from 19 different galaxies and 300 Type 1a supernovae. Scientists compare the true brightness of the stars to their apparent brightness to precisely figure out how far they are. As for supernovae, they blaze so bright that they can reliably be used to measure distance. These celestial bodies were measured using the Hubble Space Telescope.
According to the researchers, the new rate of expansion is of estimated 73.2 miles per second per megaparsec. A megaparsec is 3.26 million light-years. The distance between the cosmic objects will as much as double in another 9.8 billion years.
These rates of expansion do not match previous predictions based on measurements of the Big Bang explosion’s left over remnant radiation. Scientists presume that this discrepancy is caused by the fact that the Universe has unknown subatomic particles. These particles travel just as fast as the speed of light (186,000 miles per second).
Another theory might be that the dark energy may be shoveling galaxies apart more powerfully than previously thought. This overall resulting in the recent discovery that the Universe is expanding rapidly than believed, by 5 to 9 percent faster. About 95 percent of the cosmos is comprised by substances such as dark matter, dark energy, and dark radiation. These are mysterious elements that researchers have yet to fully understand.
Scientists are still trying to figure out a way to combine the two estimates. The new finding may also contradict Einstein’s general theory of relativity. This currently serves as the mathematical frame for calculating how the basic building blocks of matter interact. But it just might be that Einstein was wrong on this one.
A paper on the research will be published in an upcoming edition of The Astrophysical Journal.
