Our best model of the cosmos has a glaring mathematical problem, but we may have found an answer.

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians ...

How exactly did the universe start and how did these processes determine its formation and evolution? This is what a study published in Physical Review Research hopes to address as a team of ...

The inflationary universe is a research area in cosmology focused on models in which the very early universe underwent a brief epoch of accelerated, quasi-exponential expansion driven by a high-energy ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

According to The Conversation, a new study published in Physical Review D challenges the common idea that the Big Bang was the start of everything. Instead, researchers suggest it might have been a ...

New cosmology studies suggest the universe may not be perfectly uniform, potentially challenging long-standing assumptions about space, expansion, and dark energy.

The most precise measurement yet of how fast the Universe is expanding shows we have a real and serious problem on our hands.
