When inflation burst onto the scene 25 years ago, it was bold and fresh and addressed the most pressing issues in cosmology. Although there is no doubt in my mind that inflation is the most ...

Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

This period, known as cosmological inflation, lasted for only a tiny fraction of a second, but provided the initial conditions that led to the uniformly expanding Universe we see around us today. As ...

A new theory published late last year is offering an explanation as to why our universe is expanding at an accelerating rate.

The multiverse theory, a mind-bending concept, proposes that our universe is not alone. Instead, it suggests a vast sea of universes, each with its own ...

The inflation idea tidily explains many puzzles in cosmology, such as the flatness problem, the homogeneity problem and the monopole problem, and it explains the origin of structure in the ...

Inflation is now a built-in piece of our standard story of cosmic evolution. But it’s still controversial. In 2014, researchers claimed to have seen ripples from inflation imprinted on the ...

including cosmological parameters like the expansion rate of the universe, to astronomical observations that will be possible within the next decade thanks to advanced scientific satellites. To detect ...

Our research interests focus on quantum field theory and theories beyond the Standard Models in particle physics and cosmology. The main applications of our work consider phenomena in the early ...
