The Universe Is Expanding Much Faster Than Predicted: NASA

In a recent study, based upon Alberrt Einstein’s theory of relativity and released by NASA and the European Space Agency, it was claimed that the universe is expanding faster than that was believed. Many said that the release may challenge Einstein’s theories, which is a pillar of cosmology for a century.
The report, released on Thursday, claimed that the universe is expanding 5 to 9 percent faster than foretold and has no light or radiation in 95 percent of the cosmos.  “Maybe the universe is tricking us,” said Alex Filippenko, a University of California astronomer who has announced to release a separate study on similar discovery.


EXIN Times sources said that ‘the universe's rate of expansion does not match predictions based on measurements of the remnant radiation left over from the Big Bang explosion that gave rise to the known universe 13.8 billion years ago.’ It was asserted that one reason behind this deviation is that the universe has subatomic particles that can travel with a speed of light, resulting into faster expansion. Light can travel 186,000 miles (300,000 km) per second. Another idea of ‘dark energy’ was also put forward by the researchers. ‘A mysterious, anti-gravity force discovered in 1998, may be shoving galaxies away from one another more powerfully than originally estimated,’ the report said.
With a new theory in surge, it is assumed by scientists that there is possibility to dismiss Einstein’s general theory of relativity, which described the basic building blocks of universe. Sources said that Hubble Space Telescope was used to measure the distances that found a particular type of star, known as Cepheid variables, in 19 galaxies beyond our own Milky Way galaxy. Also, how fast the stars can expand is related to their brightness which again is used to calculate their distances.
