The early universe experienced a phase of rapid expansion, known as inflation. For decades, cosmologists assumed that this expansion was powered by a new entity in the universe, known as the inflaton.

SPHEREx, a new space telescope, will map galaxies, study cosmic inflation, and explore the ingredients for life. Its infrared ...

His 1981 paper heralded the virtues of inflation — an explanation for the smoothness, flatness and longevity of the Universe as well as the heat of the Big Bang — but it also challenged his ...

How it came to be that way depends on physics we barely understand, of inflationary quantum fields overcoming a remarkably ...

This initial period of rapid inflation set the stage for the vast and still-growing cosmos we observe today. Although astronomers cannot directly witness the universe's formation, much of what we ...

While parallel universes are a staple of science fiction, there are some real scientific theories to support them. But if parallel universes do exist, could we ever travel to them? It certainly wouldn ...

Hotel room bookings picked up at the end of the year, and experts think hotel stays in Orlando will increase in 2025.

Inflation occurs so rapidly that the universe is in a supercooled expansion, where the temperature drops by a factor of roughly 100,000. This low temperature persists through the inflationary stage.
