A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields ...

The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...

After 25 years of planning, six years of data collection, and six more years of analysis, scientists have published a portion of the final results of the Dark Energy Survey (DES) - the largest, most ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

NASA’s Nancy Grace Roman Space Telescope will conduct a wide-area survey to study dark matter, dark energy, and the expansion of the universe across 11 billion light-years.

Dark matter doesn’t seem to interact with the matter we can see and touch, so scientists look for it in unusual places, like ...
