For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it ...

Oscillons are spatially localised, quasi-stable configurations that emerge within scalar field theories, exhibiting coherent oscillatory behaviour over extended periods. Despite lacking a topological ...

Fuzzy scalar field theory provides an alternative framework for realising field theories on noncommutative spaces, where the classical notion of a point is replaced by a quantised “fuzzy” structure.

The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our physical understanding. For decades, cosmologists have struggled with ...

Although dark matter and dark energy make up an estimated 95 percent of matter in the universe, scientists have never observed them directly. A new experiment underway at the University of Nottingham ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe ...

“As long as they live for long enough, they will always become large cosmological beasts,” says Ricardo Ferreira, a cosmologist at the University of Coimbra in Portugal. He’s not talking about actual ...

"If the model holds true, it could mark a new chapter in the way we think about the birth of the universe." A radical new theory regarding the origin of the universe suggests that gravitational waves, ...
