the last few days pers conference The National Aeronautics and Space Administration has new images taken by the Hubble Space Telescope, and says that something strange is happening in outer space. No, that’s what they actually say:
In recent years, thanks to data from Hubble and other telescopes, astronomers have discovered another development: the difference between the expansion rate measured in the local universe compared to independent observations after the Big Bang, which predicted different expansion values.
The reason for this difference remains a mystery. But the Hubble data, which includes a variety of cosmic objects that act as distance markers, supports the idea that something strange is going on, possibly involving entirely new physics.
Since it was discovered dark energy In the 1990s, researchers were able to calculate Total of all articles in the universe. This data, with help from the powerful Hubble Space Telescope, has helped scientists track the rate at which the universe is expanding. Which is very cool! Except for now – as this press release explains – there is something turn off. Because their calculations are correct until they are not.
The universe’s expansion rate is thought to be slower than what Hubble actually saw. By combining The standard cosmological model of the universe and measurement with European Space Agency Planck Mission (which observes the cosmic microwave background remaining 13.8 billion years ago), astronomers estimate a lower value of the Hubble constant: 67.5 plus or minus 0.5 kilometers per second per megaparsec, compared to SH0ES [Supernova, H0] Team Rank 73.
Given Hubble’s large sample size, Reese said, there’s only a one in a million chance astronomers could be mistaken for pesky clouds, a common threshold for taking problems in physics seriously.
So it’s not quite as Cosmic as Lovecraftian, but still pretty weird.
