A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

We'll cut right to the chase: This video of Stanford Professor Andrei Linde finding out about yesterday's big discovery of "smoking gun" evidence of cosmic inflation (the "first tremors of the big ...

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 ...

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 ...

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American A brouhaha has erupted over the theory of ...

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.

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 ...

Update 12:05 p.m. — The team at the Harvard-Smithsonian Center for Astrophysics has announced they've found "The First Direct Evidence of Cosmic Inflation." The scientists say that after three years ...

Satellites come in all shapes and sizes, but there aren’t any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about how ...
