The Astrophysics Discovery That Could Change Cosmology

Reading some physics papers can cause a certain kind of vertigo because the authors are cautious and measured in their language, hedging every claim, but the implications lurking beneath the surface are nearly too big to handle calmly. In early 2025, a study based on observations from the James Webb Space Telescope gave several researchers that exact feeling. The discovery itself seems almost straightforward: the majority of the deep-field galaxies that JWST has seen seem to be rotating in the same direction. Approximately two-thirds rotate in a clockwise direction. The others move in an anticlockwise direction. The split ought to be 50/50 in a truly random universe. It isn’t.

Since the summer of 2022, the James Webb Space Telescope has been aimed at the universe, gathering light from galaxies that formed during the early stages of the universe with its $10 billion worth of mirrors and sensors. This coordinated rotation pattern was discovered through observations of 263 galaxies collected by the James Webb Space Telescope Advanced Deep Extragalactic Survey, or JADES survey. The team leader for the study, Lior Shamir, an associate professor of computer science at the Carl R. Ice College of Engineering, outlined the two most likely explanations. Either the universe was rotating from birth, or the formation of galaxies produces a directional bias that is not taken into account by existing models. Both choices are uncomfortable. Both call for a fundamental rethinking.

Black hole cosmology, also known as Schwarzschild cosmology, is a theory that suggests our observable universe is the interior of a black hole that exists within a larger parent universe. This theory is connected to the more radical of the two explanations. The concept is not novel. It was first proposed by mathematician I. J. Good and theoretical physicist Raj Kumar Pathria. For decades, it has remained on the periphery of mainstream physics, rarely accepted but sometimes acknowledged. The reasoning goes that if the universe originated inside a rotating black hole, it would naturally be a rotating universe. This, according to Shamir, is the most straightforward explanation for what the telescope saw. the most straightforward explanation. In a sentence about the universe being trapped inside a black hole, that phrase is doing a lot of work.

It’s important to consider how we got to the point where people are asking these kinds of questions with a renewed sense of urgency. The tale of modern cosmology is essentially one of improving instruments and reality defying expectations. The relationship between the brightness and periods of Cepheid variable stars was mapped by Henrietta Swan Leavitt in 1912. This discovery eventually made it possible for astronomers to measure distances across the universe with some degree of accuracy. Using that foundation, Edwin Hubble and his colleague Milton Humason confirmed in 1929 that galaxies were moving faster the farther they were from us. The cosmos was growing. That was peculiar enough on its own.

Then something different appeared in the late 1990s. It was discovered by two groups researching far-off supernovae that the universe was accelerating rather than merely expanding. Over time, something was pushing it outward more quickly, but no one was sure what. It was given the name “dark energy” by scientists, which is actually a catch-all for a knowledge gap.

That gap is huge: the exact nature of dark energy, which is thought to make up between 68 and 70 percent of everything in the observable universe, is still unknown. In 2024, the DESI experiment and related research revealed that this dark energy might be evolving, weakening over time instead of staying constant. If verified, that would cause significant disruptions to the conventional cosmological model. Separately, data released in early 2026 raised questions about the reliability of supernovae, which are the very instruments used to measure the accelerating expansion. It’s possible that for decades, scientists have been using a slightly bent ruler to measure the universe.

Even from a distance, it can be a little confusing to watch the accumulation of these findings. The James Webb telescope was designed to provide answers to questions about the early universe, and it has succeeded in doing so by discovering galaxies that formed earlier than the standard model predicted, necessitating revisions and sparking ongoing discussions. Along the way, however, it has also generated data that poses more complex and novel questions. a universe with a preferred direction of rotation. galaxies that shouldn’t have existed in the early universe. possibly waning dark energy. With sufficient modification, each finding on its own could be explained away or incorporated into preexisting frameworks. When combined, they create something more difficult to ignore.

It’s still unclear if the galaxy rotation asymmetry discovered in the JADES data will withstand thorough examination; before anyone can declare with certainty that the pattern is genuine and not an artifact, larger samples, independent verification, and alternative statistical interpretations will all be used. This is how science intentionally operates, and for good reason. However, the fact that a dataset supporting black hole cosmology is now being published in peer-reviewed studies and seriously discussed instead of being pushed to the periphery speaks volumes about the state of the field. There is nothing wrong with the standard model of cosmology. However, it has flaws that are getting harder to ignore with a $10 billion telescope.
