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.
......
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.”
......
the information from the JWST proposes a profound dilemma for scientists. The data indicates that there mighttbe somehitn wrong with the dark energy and cold dark matter paradigm, or ΛCDM, that has been guiding cosmology for decades.
Usually, galaxies convert around 10 per cent of their gas into stars. But the newly discovered galaxies would have to be converting almost the entirety of it into stars.
That is theoretically possible. But it is a departure from what scientists would ever have expected.
