A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further mathematical scrutiny is warranted. reading time 5 minutes Following the Big Bang, ...

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 ...

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 ...

How exactly did the universe start and how did these processes determine its formation and evolution? This is what a study published in Physical Review Research hopes to address as a team of ...

Black holes are eaters of all things, even radiation. A new study published in Physical Review Letters suggests that black ...

According to the model, dark matter may have started as particles that were hot, light, massless, and fast. As the universe ...

Two fresh ideas are giving scientists new ways to think about how the universe’s hidden mass came to be. Together, they paint a richer picture of dark matter’s origins and how we might still discover ...

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and that black holes appeared later. But some have proposed that it went the other ...
