Instead of forcing researchers to rewrite the rules of cosmology, the JWST findings have astronomers rethinking how galaxies are made, especially in the cosmic beginning.
The telescope has not yet broken cosmology, but that doesn't mean the case of the too-early galaxies will turn out to be anything but epochal.Jan 20, 2023.
The COSMOS-Webb survey will map 0.6 square degrees of the sky—about the area of three full Moons—using the James Webb Space Telescope's Near Infrared Camera (NIRCam) instrument, while simultaneously mapping a smaller 0.2 square degrees with the Mid Infrared Instrument (MIRI)..
The Feeble Glow of Filaments
The best way to see the cosmic web directly is to pick up signatures of its main component, hydrogen gas, using instruments called spectrometers, which spread light out into a multitude of wavelengths, also known as a spectrum..
Webb is a powerful time machine with infrared vision that is peering back over 13.5 billion years to see the first stars and galaxies forming out of the darkness of the early universe..

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide..
According to the "cosmic web" theory of the universe, clumps of so-called dark matter--the invisible stuff accounting for a lion's share of the universe's mass--are linked by slender filaments made of the same stuff..
A new theory suggests that it's been around for twice as long as believed.
Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models.
These models estimate the universe to be 13.8 billion years in age, based on the Big Bang expanding universe concept..
The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins.
Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system..
This “cosmic web” started out tenuous and became more distinct over time as gravity drew matter together
Astronomers using NASA’s James Webb Space Telescope have discovered a thread-like arrangement of 10 galaxies that existed just 830 million years after the big bang

In fact, one of the main goals of the Webb telescope was to discover and characterize those first galaxies, so finding galaxies in the incredibly young universe is a point in favorof the Big Bang theory, not against it
So what's the conflict, then? The apparent tension came about because of the estimated masses of those galaxies
