Webb finds more elements not possible so soon after the Big Bang
The uncertainty of science: Using the Webb Space Telescope, astronomers have now detected emissions of hydrogen from a galaxy that exists only 330 million years after the Big Bang that simply shouldn’t be possible, based on present cosmological theory.
The false-color infrared image of that galaxy is to the right, cropped to post here. At that distance, 13.5 billion light years away, all Webb can really see is this blurry spot. From the press release:
In the resulting spectrum, the redshift was confirmed to be 13.0. This equates to a galaxy seen just 330 million years after the big bang, a small fraction of the universe’s present age of 13.8 billion years old. But an unexpected feature stood out as well: one specific, distinctly bright wavelength of light, known as Lyman-alpha emission, radiated by hydrogen atoms. This emission was far stronger than astronomers thought possible at this early stage in the universe’s development.
“The early universe was bathed in a thick fog of neutral hydrogen,” explained Roberto Maiolino, a team member from the University of Cambridge and University College London. “Most of this haze was lifted in a process called reionization, which was completed about one billion years after the big bang. GS-z13-1 is seen when the universe was only 330 million years old, yet it shows a surprisingly clear, telltale signature of Lyman-alpha emission that can only be seen once the surrounding fog has fully lifted. This result was totally unexpected by theories of early galaxy formation and has caught astronomers by surprise.”
In more blunt terms, the theory that the haze would clear only one billion years after the Big Bang appears very wrong. This result is also similar to the story earlier this week about the detection of oxygen in a similarly early galaxy, oxygen that could not possibly be there only a few hundred million years after the Big Bang. Not enough time had passed for the number of star generations needed to produce it.
You can read the peer-reviewed paper here. While the Big Bang theory is hardly dead, the data from Webb continues to suggest it either needs a major rethinking, or there is something fundamentally wrong with it.
