JWST keeps showing us how much we don't know about what's out there. Love it!The James Webb Space Telescope keeps finding galaxies that shouldn’t exist, a scientist has warned.
Six of the earliest and most massive galaxies that Nasa’s breakthrough telescope has seen so far appear to be bigger and more mature than they should be given where they are in the universe, researchers have warned.
The new findings build on previous research where scientists reported that despite coming from the very beginnings of the universe, the galaxies were as mature as our own Milky Way.
Now a new paper has appeared to confirm those findings, by “stress testing” the galaxies to better understand how they formed.
It suggests that, if scientists have not made a mistake, we may be missing some fundamental information about the universe.
“If the masses are right, then we are in uncharted territory,” said Mike Boylan-Kolchin, from the University.of Texas at Austin, and the author of a new paper examining the unsual galaxies. “We’ll require something very new about galaxy formation or a modification to cosmology. One of the most extreme possibilities is that the universe was expanding faster shortly after the Big Bang than we predict, which might require new forces and particles.”……..
