Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

In case dark matter didn't seem mysterious enough, a new study proposes that it could have arisen before the Big Bang. Conventional thinking goes that the Big Bang was the beginning of everything – ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

The cosmos is riddled with evidence that the universe began with an unfathomably rapid expansion — even faster than in traditional Big Bang theories — but scientists don’t know why it happened. A ...

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 ...

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 ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

galaxies — should be bigger than recently reported, according to a new (WMAP) concluded that space is flat, or Euclidian, instead of being curved, said Dr. Richard Lieu, a professor of physics at UAH.

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

We live in a golden age for learning about the universe. Our most powerful telescopes have revealed that the cosmos is surprisingly simple on the largest visible scales. Likewise, our most powerful ...
