Let’s say you have a baby. Maybe you really do, maybe you don’t. But Dan Scolnic, a cosmologist at the University of Chicago, does have one, and perhaps that's why a hypothetical baby helps him ...

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and that black holes appeared later. But some have proposed that it went the other ...

For centuries, cartographers have sought to map Earth’s land masses and seas to better understand the world and their place in it. Now, astrophysicists have taken a major step toward doing the same ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say. When you ...

Since 1991, UChicago’s Kavli Institute for Cosmological Physics has connected students from Chicago Public Schools with world ...

Machine learning helps extract more information from galaxy surveys. Simulations of the universe train AI to identify cosmological patterns. AI can separate cosmological information from distracting ...

A six-year-old controversial theory that told of a time before the Big Bang is undergoing a resurgence, only to be lampooned again by its original critics. The theory of ekpyrotic cosmology was first ...

Not that long ago, most serious scientists considered cosmology a branch of philosophy. But in recent decades, observations by the Hubble Space Telescope and probes of the microwave radiation left ...

Thomas Kitching receives funding from the Royal Society, and the Science & Technology Facilities Council. Science is advancing rapidly. We are eradicating diseases, venturing further into space and ...

The Hubble tension just got tenser — with new measurements revealing that the universe is expanding faster than our current understanding of physics can explain. Over the past decade, cosmology has ...
