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 ...

NASA's Artemis II mission faces a delay as engineers discovered an issue with helium flow in the rocket's propulsion stage. This fault necessitates rolling the rocket back to the Vehicle Assembly ...

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 ...

In 1996 Uros Seljak was a postdoc at Harvard, contemplating ways to extract information from the cosmic microwave background (CMB). The distribution of anisotropies, slight temperature differences, in ...

For decades, scientists have relied on a popular idea referred to as cosmic inflation to explain how the universe began and why it looks the way it does today. This theory suggests the universe ...

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...

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 ...

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.

If the universe is 13.8 billion years old, why is the observable universe 46 billion light-years across? This video explains the mind-bending science behind the accelerated expansion of space and why ...
