Some astronomers say James Webb images refute the big bang theory
Over the past few days, an article has circulated on the Internet claiming that images taken by the James Webb Telescope (JWST) have debunked the big bang theory.
JWST is able to see the early days of the universe. However, an article titled “The Big Bang Didn’t Happen” claims that the JWST images somehow “caused panic among cosmologists” because they contradict the Big Bang theory.
The author of the article, Eric Lerner, goes on to quote another astronomer, Allison Kirkpatrick of the University of Kansas:
“Right now I’m lying awake at 3am wondering if I did everything wrong.”
“A friend warned me about this article and now I can’t stop getting emails applauding me for my bravery in making the Big Bang wrong,” she tweeted.
Kirkpatrick talked about various new data showing that galaxies have disks much sooner than we expected. While this may require adjustments to galaxy formation theories, it by no means revises the Big Bang theory, which Kirkpatrick did not refer to.
In fact, Kirkpatrick suggests that the JWST images “support the Big Bang model because they show us that early galaxies were different from the galaxies we see today – they were much smaller.”
In one part of the paper, Lerner seems to suggest that stars have been discovered that are older than the Big Bang theory would allow, and that since the JWST can see the color of distant galaxies, the red color of distant galaxies means they contain very old stars.
“According to the Big Bang theory, the most distant galaxies in JWST images are seen as they were only 400-500 million years after the beginning of the universe,” Lerner wrote.
“However, some galaxies have already shown stellar populations that are over a billion years old. Since nothing could have come into being before the Big Bang, the existence of these galaxies demonstrates that there was no Big Bang.”
Bu as Brian Keating points out, “We first have to make sure the calibration between redshift and distance is done” because the expansion of the universe causes a redshift.
At best, the papers Lerner cites suggest that we may need to revisit our theories about galaxy formation in order to explain how stellar disks appeared so quickly.
According to NASA, a rogue, hyper-speed object, which is over
27,306 times the size of Earth, is hurtling so fast through our galaxy
that it might break free of the Milky Way.
Scientists say they have determined that the mysterious object was
cruising at a breakneck one million miles per hour when they spotted it
more than 400 light years from Earth. One light-year is equal to six
trillion miles.
Could this latest find be connected to the fake alien invasion that has long been in the pipeline?
The Mail Online reorts: While experts have not determined what the newfound celestial body is, they speculated it is a ‘brown dwarf,’ a star which is larger than a planet but lacks the mass to sustain long-term nuclear fusion in its core like Earth’s sun.
If the object confirmed as a brown dwarf, it would be first-ever to
be documented in a chaotic, hyper-speed orbit capable of breaking free
from our home galaxy.
A coalition of citizen-scientists with NASA’s ‘Backyard Worlds: Planet 9’ projectwere the first to spot the celestial body, the US space agency confirmed this week.
‘I can’t describe the level of excitement,’ German citizen-scientist Martin Kabatnik, a long-time member of NASA’s Backyard Worlds program, said in statement.
‘When I first saw how fast it was moving,’ the Nuremberg-based
researcher confessed, ‘I was convinced it must have been reported
already.’
Backyard Worlds citizen-scientists Martin Kabatnik, Thomas P. Bickle
and Dan Caselden were the first to spot this million mph object a few
years ago, earning the hyper-speed object the catalogued name CWISE
J124909.08+362116.0.
According to astronomer Dr Kyle Kremer,
who has collaborated with them on better understanding the object,
several astrophysics theories could explain how the object, CWISE J1249
for short, could have gotten to its incredible speed.
In one theory, CWISE J1249 rocketed out of a two star or binary star
system after its ‘white dwarf’ sister star died off — collapsing in an
explosive runaway nuclear fusion reaction called a supernova.
Another viable theory has it that CWISE J1249 originated inside a
tight cluster of starts called a ‘globular cluster’ where it was flung
free via the pull of a black hole.
‘When a star encounters a black hole binary,’ Dr Kremer said in a
NASA statement on the discovery, ‘the complex dynamics of this
three-body interaction can toss that star right out of the globular
cluster.’
Sławosz Uznański will be the second Pole in space and the first to fly to the International Space Station (ISS).
Uznański revealed that his mission to the ISS is planned for 2025 and will last about two weeks. He will launch from Cape Canaveral on a rocket provided by SpaceX. This journey not only represents a significant milestone for Uznański but also for Polish space exploration.
Last year, Uznański was officially selected for this mission, after which he commenced his training at the European Space Agency’s facility in Cologne, Germany. Initially planned for 2024, the mission faced delays, but new details have recently emerged on Uznański’s social media profiles.
During his two-week stay on the ISS, he will focus on Polish scientific projects and technology tests, including artificial intelligence applications in space and studies on the effects of microgravity on the human immune system.
The European Space Agency (ESA) and the Polish Space Agency (POLSA) received numerous project proposals for Uznański’s mission. Due to limited space, only seven were selected, highlighting the extensive interest and potential impact of this mission.
Uznański will travel to the ISS in SpaceX’s Crew Dragon capsule, a vehicle regularly used by NASA for transporting astronauts. The Crew Dragon will be mounted atop a Falcon 9 rocket, with the launch also set to take place at Cape Canaveral. While the exact launch date is yet to be confirmed, preparations are in full swing.
In a move to further his training, Uznański has relocated to Houston, Texas. Starting Monday, he will begin a new training phase at Axiom Space, a partner in the mission, followed by sessions at NASA and SpaceX facilities. This mission not only propels Uznański into space but also significantly advances Poland’s stature in the global aerospace sector.
