By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Cosmic inflation solves these problems at a stroke. In its earliest instants, the universe expanded faster than light ( light’s speed limit only applies to things within the universe).

This fascinating hypothesis also challenges various theories such as string theory and cosmic inflation. Turok's theory states that the universe before the Big Bang might be a mirror image of our ...

First, cosmic inflation must be proved. This theory describes the universe’s superluminal expansion that occurred less than a second after the Big Bang. Second, the existence of fuzzy axions — a ...

The early universe ... inflation took the quantum foam of space-time and expanded it to larger scales, laying down the gravitational seeds that would someday grow up to be stars, galaxies and the ...

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.

Inflation, in the context of the big bang theory, refers to the episode of exponential expansion of the very early universe indicated by particle ... initial conditions for a specific scenario of how ...

This bold concept could address dark matter mysteries and explain cosmic symmetry gaps. In Turok’s hypothesis, right-handed neutrinos—unobserved in our universe—could exist in the mirror ...

A powerful combination of data from two very different astronomical surveys has allowed researchers to build a "cosmic CT scan" of the universe's evolution. These snapshots reveal that, as forces like ...

The early universe experienced a phase of rapid expansion, known as inflation. For decades ... because that's exactly what we observe in the cosmic microwave background, the leftover light ...
