9% faster universe expands, scientists reveal – Newscasts Televisa

WASHINGTON, United States, jun. 3, 2016.- The astronomers thought they knew the behavior of the universe, but perhaps the cosmos is making them dirty tricks.

A team of astronomers has calculated that the universe appears to be expanding faster than they had determined before the scientists. If the new research is correct, the basic understanding of the science of what has been happening in the universe in the last 13,800 million years after the Big Bang might be a little upset.

“This is in really a test that puts us the universe. is how our final exam, “said Nobel laureate and lead author of the study, Adam Riess, of the Institute of Space Telescope Science

the astronomers used the telescope Hubble space to measure the distance of 2,400 stars to calculate the expansion rate of the universe. They determined that is between 5 and 9% faster than other scientifically accepted measurements calculated the expansion rate based on the cosmic background radiation from 380,000 years after the Big Bang.

NASA released Thursday the new study will be published in the Astrophysical Journal.

or any of the calculations are wrong to external scientists regard as the most likely, although they could not find anything wrong yet or the rate of expansion has accelerated from 13,800 million years ago.

and if this is the case, as says Riess, then our understanding of the universe is not entirely correct.

it’s like looking for someone and we are in the right room, but we are seeing the wrong wall, said Riess, who won the Nobel prize for Physics in 2011 for demonstrating in 1998 the acceleration of the universe. So now, Riess and many of the same scientists are trying to figure out where astronomy took the wrong turn.

Riess and coauthor Alex Filippenko, Berkeley, said there are many possible explanations for why the universe expands faster now: could it be that there is a mysterious particle, which scientists call sterile neutrino, which has not been seen but it could change the calculations and loosen the cosmic calculations. It could be an increase of dark energy. Perhaps it is because the universe is more curved than had been considered. It could be that General Relativity of Einstein is not so correct when we observe the universe.

Or it could be that measurements have deficiencies.

“There is perhaps something very exciting, very interesting that information trying to tell us about the universe, “said Filippenko.

the NASA astrophysicist John Mather, astrophysicist David Spergel, Princeton, and physicist Sean Carroll of the California Institute of Technology, say that although we may have to return to the cosmological drawing board is much more likely that one of the two measurements of the expansion rate was miscalculated somehow.

“it is premature to say that the universe is picking on us, “said Carroll, but added that scientists responsible and careful measurements made both.
