Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests the missing ...
Possible interactions between dark matter and neutrinos may help explain a persistent mismatch in how cosmic structure evolved.
A new theoretical framework suggests dark matter’s elusive behavior may arise from the geometry of a hidden fifth dimension.

Mirror universe where time runs backwards could help explain dark matter, antimatter and neutrinos
The Big Bang may not mark the absolute beginning of everything. A controversial cosmological model instead treats it as a boundary, with our universe on one side and a time-reversed anti-universe on ...
Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei of a radioactive element ...
Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered ...
Atomic clocks have been around for nearly 80 years, but their successors—nuclear clocks—are ready to take the stage. Two independent studies, both uploaded as preprints, report reliable timekeeping ...
It is a basic fact in modern astrophysics that we don’t know what most of the universe is made of. The familiar objects around us that are made of matter and energy — people, planets, stars — account ...
Peering far into the distant, high-redshift universe, the James Webb telescope has discovered an abundance of small red galaxies known as the Little Red Dots. From their observations, astronomers ...
