Is Dark Energy Unnecessary? Mathematicians Challenge Standard Cosmological Model of Universe

This artist’s impression shows the evolution of the Universe beginning with the Big Bang on the left followed by the appearance of the Cosmic Microwave Background.

May 28, 2026 by News Staff

Mathematicians from University College London and the University of California, Davis, have published a mathematical proof that the Universe’s accelerating expansion can be explained without dark energy, dealing a serious blow to the Lambda-cold dark matter model — the standard cosmological model that has stood for nearly 30 years. Alexander et al. provide a mathematical proof that instabilities inherent in the Einstein-Euler equations imply...

Participants with intracranial electrodes listened to two competing, spatially separated conversations. Their neural signals were recorded and fed into a real-time processing system. The system uses a linear regression model to reconstruct the temporal envelope of the attended speech from low-frequency (LF) and high-gamma (HF) neural features. The reconstructed envelope is then compared to the envelopes of the two conversations to determine the listener’s focus, which in turn drives the selective amplification of the attended speaker.
