New observations suggest that the universe’s oldest galaxies are brighter than expected. Here's why this may be a big deal.

The study says that the gravitational distortions observed in distant galaxies exhibit subtle discrepancies with the ...

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

A multi-institutional team of physicists is proposing an experiment to test whether gravity behaves as a quantum entity when ...

The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology. Professor Albion Lawrence ...

Dark matter, a mysterious substance thought to make up most of the universe's mass, has puzzled scientists for nearly a ...

If another gravity theory is correct, "then the broader implications are enormous," astrophysicist Stacy McGaugh told ...

Why is the expansion of our universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...
