A series of viral social media posts drew attention to an old cosmological theory-that our universe began from a collision between two separated universes-as a brand new scientific ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, ...

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 ‘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.

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 ...

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 ...
