Observations of the thermal energy in a baby galaxy cluster 12.4 billion light years away suggest much more energetic early cluster growth than current theories assume ...

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

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

Right now, it looks like cosmology is at a tipping point. Will the James Webb telescope resolve the issue by revealing new physics? When you purchase through links on our site, we may earn an ...

Scientists from the University of Sheffield suggest that dark matter and neutrinos may interact, challenging existing ...

The clearest pictures yet of the newborn cosmos strengthen the prevailing model of the universe but deepen a mystery about its expansion rate. Measurements of this rate, known as the Hubble constant, ...
