Original Coverage: Dark Matter Could Be Evolving, And The Implications Are Profound
Researchers have proposed a new way to look at dark matter in the Universe. The new model would allow for the Hubble tension to be covered while still matching the dark matter observations we have. Neutrinos have mass and don’t interact strongly with light, they are a form of hot dark matter. And cold dark matter particles undergo a similar oscillatory effect. The authors find that the best fit to observational data is a Universe where about 15 percent of the cold. dark matter is oscillatory and the remaining 85% is standard dark. matter. They note that this work presents a toy model and that it does not pin down specific constraints for dark matter particle size.

New Evidence Reveals Dark Matter Might Be Evolving — And The Impact Is Far-Reaching
A new study challenges one of the most fundamental assumptions in cosmology: that dark matter remains constant over time. The new theory posits that around 15% of the dark matter could have an oscillatory behavior in its equation of state. This idea draws inspiration from neutrinos, which undergo mass oscillations despite being weakly interacting particles. If cold dark matter particles share similar oscillatory properties, it could have profound implications for the formation and evolution of cosmic structures. The authors of the study emphasize that their model remains a “toy” or broad conceptual framework, not yet providing precise constraints on the nature or identity of these oscillatory dark Matter particles. Future observations, especially from large-scale surveys like DESI (Dark Energy Spectroscopic Instrument), will be crucial in testing these predictions.

New DESI Results Strengthen Hints That Dark Energy May Evolve
Discovery of the universe’s dark matter is the result of a series of events. The data was collected using a technique known as gravitational lensing. It is the first time the data has been combined with other data to reveal the full extent of the dark matter universe. The results are expected to be published in the next few months, with more data expected to come in the future.
