How did the universe begin? A compact NASA space telescope that uses less power than a refrigerator is poised to chip away at that very large question. Called SPHEREx, and set for launch on a SpaceX ...

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 ...

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 ...

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 ...

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 ...
