The sudden expansion of the universe during its inflationary period created ripples in space-time in the echo of the Big Bang. One can think of the Big Bang, in oversimplified terms, as an ...

Our galaxy may reside in a billion-light-year-wide cosmic bubble that accelerates local expansion, potentially settling the ...

This schematic diagram of Lambda-Cold Dark Matter, accelerated Expansion of the Universe Via Alex Mittelmann, Coldcreation. In August of 2013, physicists made a major breakthrough in our ...

The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles.

A trillion years ago, our universe didn’t exist, at least not in any recognizable form. According to the Big Bang theory, ...

In fact, our entire observable Universe contains no signatures at all from almost all of its pre-hot-Big-Bang history; only the final 10-32 seconds (or so) of inflation even leave observably ...

But a team of researchers has proposed a new idea.They argue that our inflation and Big Bang Nucleosynthesis eras were not alone. Dark matter may have evolved along a completely separate trajectory.

How did everything begin? It's a question that humans have pondered for thousands of years. Over the last century or so, ...

During inflation, the entropy of our Universe must have been much, much lower: around 10 15 k B for a volume equivalent to the size of our observable Universe as the start of the hot Big Bang ...

The Big Bang holds that our universe was born 13.7 billion years ago, in a massive expansion that blew space up like a balloon. Here's a brief rundown of what astronomers think happened, from the ...
