For a long time, scientists believed they understood how fast the universe is expanding.
But it seems that the more we learn about it, the more it expands.
Basically, Hubble measures the rate at which the universe is expanding. The only problem? Different instruments continue to provide different values for it, causing what is known as the "Hubble tension", he writes yahoonews, the Telegraph reports.
This raises the interesting possibility that, as Nobel Prize-winning physicist Adam Riess explains, much of what we thought we knew about the universe may have been wrong.
Meanwhile, the discrepancies are further deepened by measurements by various telescopes of the Hubble numbers, including measurements by the James Webb telescope.
According to NASA, Webb should be able to reduce noise and obtain more accurate images from space and more accurate distance measurements.
This is because when telescopes see more stars than they can handle, it can affect their measurements.
"With measurement errors, the real and most exciting possibility remains that we have misunderstood the universe," Riess said. /Telegraph/
