A new cosmic deep field map from the COSMOS collaboration,
powered by the James Webb Space Telescope, is rewriting what
scientists thought they knew about the early universe.
Spanning nearly the full history of cosmic time and featuring
nearly 800,000 galaxies, the data shows a universe forming
stars and supermassive black holes far earlier—and in greater
numbers—than previously predicted. This unprecedented scope
offers a mural-scale view of the universe’s youth and has
left researchers wondering if their core cosmological models
still hold.
. . .
I'm starting to think the universe is older and
bigger than we previously calculated.
There may be far more galaxies out there that even
the Webb isn't tuned to see - or may even be beyond
the speed-of-light time horizon.
We may not need an entire Webb-II to confirm this,
some other investigative scope that goes considerably
further into the IR band that doesn't need as much
resolution. Note funding issues, another Webb will
likely be too much for a long time.
Deep-IR and high-microwave scopes can eventually be
built on the 'dark side' of the moon, eventually.
Those can be of almost arbitrary size. Alas, 50
years likely ...
Seems like every time scientific instrumentation
gets twice as good we have to re-write a lot of
science.
