Does our universe exist inside a black hole? Here's what the discovery says

When Lior Shamir, a scientist at Kansas State University, examined images from the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES), he saw something completely unexpected.
Most of the 263 galaxies he observed rotated in the same direction, with two-thirds rotating clockwise, Shamir reported in the Monthly Notices of the Royal Astronomical Society.
Why is this important? In a random universe, the rotation of galaxies should be equally divided in two directions.
The fact that this does not seem to be the case in our universe suggests that other forces, which we do not yet fully understand, may be at play.
"It is still not clear what causes this phenomenon, but there are two main possible explanations," Shamir said in a press release.
"One explanation is that the universe was born spinning. This explanation is consistent with theories such as black hole cosmology, which assumes that the entire universe is inside a black hole."
But if the universe really did start spinning, that means existing theories about the cosmos are incomplete.”
Another surprising aspect of the study was that this effect was clearly visible. "The study suggested that you don't need to be an astrophysicist to identify the phenomenon.
"The difference is so extreme that it can be observed and analyzed even with the naked eye," the study authors said.
"It doesn't take special skills or knowledge to see that the numbers are different."
"With the power of the James Webb Space Telescope, anyone can see this," Shamir added in the statement.
Although the theory that the Universe is inside a black hole is intriguing, there may also be a simpler explanation for these unexpected observations: some previous measurements about our universe may be inaccurate, particularly the speed at which our galaxy, the Milky Way, rotates.
Since Earth orbits the center of the Milky Way, researchers expect the Doppler shift effect to affect their observations of the galaxy's velocity.
This effect occurs when an observer detects waves from a moving object. The most common example is the way the sound of a train whistle appears to change as the train speeds past an observer.
Light waves are also subject to the same effect and, in this case, can make light coming from galaxies that rotate in the opposite direction to Earth's rotation appear brighter.
If astronomers have miscalculated the impact of this effect, or simply got the Milky Way's rotational speed wrong (which is considered significantly slower compared to other galaxies), then they may need to reconsider some basic assumptions.
"If this is the case, then we will need to recalibrate our distance measurements for the deep universe," Shamir said.
"Recalibrating distance measurements could also explain several other unresolved questions in cosmology, such as variations in the expansion rates of the universe and the existence of large galaxies that, according to existing distance measurements, are expected to be older than the universe itself."
However, the conclusion is that both explanations for the uneven rotation of galaxies will force astrophysicists to reconsider some aspects of our Universe.
