When you look into the vastness of space, there’s a puzzling pattern in how galaxies spin. Most of them seem to rotate in the same direction, which raises a big question. According to current science, galaxies should be spinning every which way. So why are we seeing this unusual trend?
Astronomer Lior Shamir from Kansas State University has two ideas about what’s happening. First, maybe the entire Universe started out with a spin. This theory ties in with concepts like black hole cosmology, suggesting that our Universe might be inside a black hole. If true, this could mean our current theories about the cosmos are missing crucial pieces.
The second possibility is far less exciting: it could just be an optical illusion caused by the way our Milky Way spins. This means what we see could be distorted, making it seem like more galaxies are turning one way over the other.
Despite looking chaotic at first, the Universe isn’t completely random. There are vast networks of dark matter creating a gravitational web that connects galaxies. Scientists thought that galaxies’ spins would be scattered, but Shamir’s previous work shows a surprising order.
In his latest study, he explored the spins of 263 galaxies whose light has traveled billions of years to reach us, using data from the James Webb Space Telescope’s Advanced Deep Extragalactic Survey (JADES). He found that out of these galaxies, only 105 rotate counterclockwise while 158 rotate clockwise. This clear imbalance suggests something deeper is at play.
Shamir explains that the differences in spin are noticeable even without complex calculations. The power of the James Webb Space Telescope allows anyone to see this intriguing pattern.
This leads us to a more curious perspective—what if we really do live inside a black hole? It sounds strange, but other explanations for the spin imbalance could offer some clarity. For instance, our own galaxy’s rotation might skew the appearance of those spins, making certain galaxies look like they spin differently than they actually do.
If this theory holds water, it could help solve other cosmic mysteries like the Universe’s expansion rate. Shamir notes that recalibrating our distance measurements might align more closely with our understanding of cosmic events. His findings contribute to a growing conversation in the scientific community about how we understand the Universe.
