The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

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

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

Physicists theorize our universe may have collided with another in the past, creating the Big Bang. Level two of the ...

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

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a ...

For two decades, scientists believed the cosmological constant, known as λ (lambda), was positive. That meant the Universe would keep expanding indefinitely.

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 ...

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

If these knots had a slight bias toward matter over antimatter, their unraveling could help explain the matter-antimatter ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...
