Science experts are reportedly baffled and that the ‘universe doesn’t look right’ anymore..
VARIOUS NEWS SOURCES REPORTING THE SAME INFO: THE UNIVERSE SUDDENLY LOOKS WRONG..
?>? What does this mean?
The WASHINGTON POST is the main story for the report.. and says this among other things: https://www.msn.com/en-us/news/technology/scientists-are-baffled-whats-up-with-the-universe/ar-AAJG967
The universe is unimaginably big, and it keeps getting bigger. But astronomers cannot agree on how quickly it is growing — and the more they study the problem, the more they disagree. Some scientists call this a “crisis” in cosmology. A less dramatic term in circulation is “the Hubble Constant tension.”
AND THIS
This summer, as leaders in the field assembled in Santa Barbara, Calif., to discuss the “tension,” physicist Wendy Freedman of the University of Chicago presented a new estimate of the constant that was based on examination of red giant stars. Her number: 70. But the advocates for 67 and 73 held their ground. The tension remained. Freedman told The Washington Post, “There can’t be three different numbers.”
There are more than that, actually. On Oct. 23, researchers at the University of California at Davis published a paper that looked at three gravitational lenses — in which massive galaxies function like magnifying glasses for things behind them in deeper space. Their number: 77.
It could be simply that some of the measurements are based on erroneous assumptions. Imagine two speed guns giving strikingly different measurements of Max Scherzer’s fastball. One obvious, boring explanation is that one of the speed guns needs to be recalibrated.
It’s conceivable, for example, that astronomers haven’t fully factored in the way cosmic dust can interfere with observations, which wouldn’t be the first time that has happened. But the more delicious possibility is that there’s something new to be discovered about the way the universe evolved.
One idea floating around is that there could have been something called Early Dark Energy that skewed the appearance of the background radiation.
