The universe expands faster than we thought

The universe expands faster than we thought

A new study indicates that the universe seems to be younger than we think and also, its expansion is faster. If this is the case, we need a new physics to explain it.

A study led by a Nobel prize winner has found that the universe is younger than we thought, and is expanding faster than we imagined. Astronomer Adam Riess used measurements sent by the Hubble Space Telescope to conclude that the universe expands 9% faster than previously calculated.

Reiss along with other scientists think that these new calculations could be the right ones, so the expansion of the universe could’ve increased. And to make things more complicated, explaining this would require a new physics.

Astronomer has calculated that the universe is between 12.5 billion and 13 billion years old, this is younger than the previously accepted values of 13.6 billion and 13.8 billion years. The calculations are based on what would happen after the Big Bang. However, all this probably still requires more work to confirm the aforementioned data.

Riess is an astronomer at John Hopkins University, who published this week in the Astrophysical Journal, his findings about the true age of the universe, using data from the Hubble telescope, which could now give a new speed of expansion of the Universe, a matter that scientists have theorized for many years. Reiss indicates that “the universe is surpassing all our expectations and that is really very intriguing.”

For his part, NASA astrophysicist John Mather, who has also won the Nobel prize, said that the two expansion speeds of the universe could be due to two possibilities: “1. We’ve made mistakes we don’t know what they are yet or 2. Nature has something we still don’t know what it is. ” However, Reiss cancels the possibility of human error. He said that the difference between the above and the new data “has reached a point that is really impossible to consider an error in the calculations. This is not what we expected. ” And he adds, “It’s not just that the two experiments disagree.”

Reiss thinks that “we are measuring something fundamentally different. One is the extent to which so fast the universe expands today and the other is the physics-based prediction of the initial universe and the measures on how it would have expanded. If these values disagree, it is very likely that we are forgetting something in the cosmological model that connects the two eras. “

In order to explain this, theories have already emerged about it, such as the mysterious “dark energy”, a substance that no one really knows what it is, but that could be accelerating the expansion of the universe. Astrophysics Wendy Freedman, said that both calculations seem to be valid and that no one has found any errors in any of the calculations. If this is the case, astrophysics has a problem that perhaps with current physics cannot be solved.

We will follow in detail the news that comes out on this subject. The speed of expansion could be a fundamental result of physics and we also assume that there is a reason for this expansion reason. We’ll have to track it down.
