Observations don’t match the predictions of the standard model—and it’s not just a fluke.

The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified picture of the Universe. GENEVA, SWITZERLAND ...

For measuring curvature of 3D (hyper) surface we need solid angles instead of plane angles. General relativity (GR), which explains events on the greatest cosmological scale, and quantum mechanics (QM ...

The properties of faint dwarf galaxies around the Milky Way can reveal a lot about the conditions of the early universe, the ...

Relax, it’s only happening in theoretical physics—at least for now.

Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new ...

Dwarf galaxies that orbit the Milky Way and the Andromeda galaxies defy the accepted model of galaxy formation, and recent attempts to wedge them into the model are flawed, reports an international ...

For just one-tenth of a second in May 2019, the universe delivered a signal that did not fit the usual script. LIGO and Virgo ...
