The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period ...

If evidence confirming the gravitational-bounce model is measurable, the impact could change cosmology forever. Following the ...

Scientists have developed a groundbreaking tool called Effort.jl that lets them simulate the structure of the universe using ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark ... The researchers propose a model in which collapsing massive stars produce black holes that convert ordinary ...

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

Using the James Webb Space Telescope, astronomers have captured the clearest picture yet of how galaxies formed in the early universe.

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from ...
