According to a new study published as an Editor’s Suggestion in Physical Review D, researchers from The University of Tokyo ...

Researchers have shown that a discrepancy in a key cosmic measurement in the early universe originates from a subtle ...

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

The mysteries surrounding the origins of the universe have long intrigued scientists and philosophers alike. New research, published in the Living Reviews in Relativity, introduces an innovative ...

A team of scientists proposes a new model of cosmic inflation that reveals how gravity and quantum mechanics may be sufficient to explain how the structure of the cosmos came into being. A team of ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

According to a new theory, our universe developed from a “pre-inflationary multiverse” made of particles in quantum superposition.

The James Webb Space Telescope, launched in 2022, has discovered something that may shatter current theories about the universe's early development. The new result does not affect the big bang theory, ...
