A new study using data from NASA's James Webb Space Telescope on 263 galaxies has brought forward new evidence for a surprising theory.
The theory suggests that our universe could be inside a black hole that formed in a much larger universe, according to Digi24.
Researchers from Kansas State University have discovered that most galaxies in our universe rotate in the same direction.
This challenges the idea that our universe is isotropic, meaning there should be an equal number of galaxies rotating in both directions.
Lior Shamir, an associate professor of computer science, explained that there are two main possible reasons for this.
One explanation is that the universe was born in rotation. This fits with the theory of black hole cosmology, which suggests that our universe exists inside a black hole in a larger universe.
According to this theory, the Milky Way and all other galaxies would be inside a black hole formed in a much bigger universe.
This idea goes against several widely accepted theories in cosmology, such as the Big Bang theory, which claims that the Big Bang marked the start of our universe.
Though the new findings are intriguing, they don't definitively prove that the universe is inside a black hole.
More evidence is needed to fully understand the implications of this model. Another possible explanation for galaxies rotating in the same direction is that the Milky Way's rotation might distort the data.
If this is the case, scientists would need to adjust their methods for measuring distances in the universe.
Adjusting these measurements could also explain other mysteries in cosmology, like why the expansion rates of the universe and large galaxies don't quite match up with expectations.
The study was published in Monthly Notices of the Royal Astronomical Society.
While the theory is still far from being proven, it opens up fascinating new possibilities for understanding our universe and its origins.
