The universe is expanding faster than we thought, and no one knows why

Explaining a discrepancy between what was happening 13 billion years ago and now may require new physics.

It's become clear that something in the cosmos just doesn't add up. The universe is getting bigger every second. In fact, it's expanding at a much faster rate than it should.

For some time now there's been a mismatch in observations of the early universe done with the European Space Agency's Planck Telescope and what astronomers see when they measure the more nearby, modern parts of space with NASA's Hubble Telescope. (Keep in mind that looking at distant parts of the universe with powerful telescopes is the same as looking back in time).

When scientists look at what was going on 13 billion years ago, via Planck, and then extrapolate that into the present, the results don't match what Hubble sees today. For several years, there's been an assumption that the disagreement is due to a lack of precision in the measurements. But as scientists have fine-tuned their tools, the discrepancy has remained. On Thursday, researchers using Hubble said the chances the mismatch is some sort of user error or fluke have gone from 1 in 3,000 to 1 in 100,000.

"The Hubble tension between the early and late universe may be the most exciting development in cosmology in decades," lead researcher and Nobel laureate Adam Riess of the Space Telescope Science Institute, which leads Hubble's science mission, said in a statement. "This mismatch has been growing and has now reached a point that is really impossible to dismiss as a fluke. This disparity could not plausibly occur just by chance."

The Hubble team's results have been accepted for publication in The Astrophysical Journal.

Riess says the discrepancy strongly suggests there's a piece missing in the puzzle that scientists have put together over the years to model the history of the universe.

One possible explanation could be the appearance of dark energy at some point long ago. It's now theorized that up to 70 percent of the universe may be made up of the mysterious stuff. A yet undiscovered and speedy particle in the universe that affects its expansion is another possibility, as is the idea that unseen dark matter might be pushing on the normal matter we can see more strongly than we thought.

The actual explanation remains a mystery. Riess and other scientists plan to continue fine-tuning their tools and measurements, but if the mismatch isn't due to human error, new physics may be needed to complete the puzzle.

"Previously, theorists would say to me, 'it can't be. It's going to break everything.' Now they are saying, 'we actually could do this,'" Riess said.

the same type of mathematical models are used to determine all of this. while the models are not the same the one for universe expansion shows how little trust we should have for the mathematical models on climate change. this is the main reason I don’t believe scientists when they talk about the dangers of the earth over heating. Lots of educated people in areas like biology or chemistry take a look at theses mathematical models and look at something like a glacier melting and say must be global warming because that mathematical model says that the world is warming and ask how can we prove that it is global warming rather then exploring other possibilities..

“The universe is expanding faster than we thought, and no one knows why”

that’s probably why commuting keeps taking longer and longer ...

Maybe, just maybe, our little spot is being sucked back toward the origin while distant spots are still zipping away from the origin. Just sayin’

In “Day One”? Look again. On IMDB he’s sort of down there in the cast, but his role was larger.

They are intellectually and physically lazy bastards.

‘Computer Modeling’ isn’t science. It’s a Video Game for geeks.....................

Gravity compresses Time.

Ergo

Lack of Gravity expands Time.

As the Universe expands, the effects of gravity become less and less so it appears to be going faster that it did when it was more ‘compact’.

Einstein right again.....................

I think its more that they lack the ability to think creative...most of those educated in the university system just trust that an expert in a area is right they don’t understand that the truth in science always should be Questioned. lots of times highly trained individuals will default to there education when a falicy in the science is exposed. this is because they never truly understood what they studied in an interactive way with the knowledge they were presented. for most educated individuals they don’t have a understanding of there science instead they have a recipe book understandin out the alternative explanation for Z unless the alternative was given. thay cant see that there are many ways to Z.

Real science.
