Is the Universe hiding a secret? New James Webb findings suggest most early galaxies spun in the same direction
Everything in the cosmos is in motion: stars, planets, and galaxies all partake in a grand celestial dance. Some rotate clockwise, others counterclockwise. For decades, scientists assumed these spins would balance out. But fresh observations from the James Webb Space Telescope are challenging that assumption in surprising ways.
James Webb’s primary mission is to peer deeply into the cosmos and illuminate how the first galaxies formed after the Big Bang. Over nearly three years of operation, the telescope has delivered breathtaking images and a wave of discoveries—some thrilling, others perplexing. The latest result is particularly provocative, prompting researchers to rethink a cornerstone idea about the early Universe.
Most early galaxies appear to rotate in the same direction
A team from Kansas State University reports a striking pattern in the Monthly Notices of the Royal Astronomical Society: the majority of early galaxies seem to spin the same way.
“It’s almost obvious when you look at the data,” says Lior Shamir, a computer science professor and the study’s lead author.
Traditionally, astronomers expected near-equal numbers of clockwise and counterclockwise galaxies. Yet analysis of James Webb data shows that roughly two-thirds rotate clockwise. In other words, the early Universe might have had more order than previously thought, and this wasn’t anticipated.

Reality or perceptual bias?
What explains this pattern? The researchers propose two possibilities. One is that the Universe itself could have originated with a rotation. If that were true, we should see a telltale imprint in the cosmic microwave background radiation, but so far no such imprint has been detected. This idea touches some of the boldest theories in physics, including notions that our Universe might reside inside a colossal black hole. “If the Universe did begin spinning, our current models would be incomplete,” Shamir notes.
A second possibility is more conventional but still provocative: the observed dominance of clockwise spins could be an illusion. Since the Earth orbits the center of the Milky Way, our own motion might subtly bias how we perceive distant galaxies, especially in how we measure their brightness when they spin in different directions. Until now, astronomers treated this effect as negligible, but the latest results suggest it may deserve a second look.
If this bias plays a role, researchers might need to recalibrate deep-space distance measurements. That recalibration could ripple into other cosmological puzzles—such as why the Universe’s expansion rate appears to differ across observations or why some massive galaxies seem older than the Universe itself.
Whether this finding reflects a fundamental clue about cosmic beginnings or a perceptual illusion, one thing is clear: the James Webb Telescope continues to remind us that the Universe still harbors deep mysteries.
