Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

A former Harvard physics professor argues that established cosmological theory places Heaven beyond the observable universe, ...

In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

Astroparticle physics and particle cosmology represent converging disciplines that strive to understand the universe from its largest structures down to its most fundamental constituents. In this ...

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Michael Boylan-Kolchin and others show “early dark energy” might help solve the Hubble Tension and explain why there are more early galaxies than expected. A panel of physicists and astronomers ...
