A new study suggests that the cosmic web could have formed without relying on inflation driven by a scalar field. Instead, it ...

For decades, scientists assumed that the expansion of the universe was powered by a new entity, known as the inflaton, but ...

According to new research, the earliest seeds of structures may have been laid down by gravitational waves sloshing around in ...

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 ...

What if its origin dated back not to the hot phase of the Big Bang, but to cosmic inflation, that period of rapid, exponential expansion? According to a study published in *Physical Review Letters ...

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.

Researchers from the University of Texas at Austin (UT Austin) have proposed a new model to explain the origin of dark matter. It suggests that dark matter originated during the infinitesimally ...

Cosmologists believe that our universe underwent a period of incredibly rapid expansion known as inflation. Powering this event was some mysterious substance in the universe, known as the ...

Primordial nucleosynthesis after embryonic inflation, the subject of Chapter 6, yields spatially varying abundances of elements, including heavy elements in all the densest cosmic regions. The theory ...
