Might the universe we can observe be just half the tale, with a mirror universe moving in reverse through time filling out the narrative? A new and intriguing idea from scientists at the Perimeter ...

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 ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

Neil Turok does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

For a fraction of a second after the big bang occurred 13.8 billion years ago, most physicists believe, the newborn universe dramatically ballooned in size, jumping from being smaller than a proton to ...

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 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 ...

The new model is called WIFI, which stands for dark matter production during Warm Inflation via Freeze-In. According to a new model, dark matter particles (black dots) began forming as the universe ...

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 ...

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.

For a fraction of a second after the big bang occurred 13.8 billion years ago, most physicists believe, the newborn universe dramatically ballooned in size, jumping from being smaller than a proton to ...
