A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

But new studies suggest that one of his most famous ideas, the cosmological constant, may not be fixed after all. If true, it ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

University of Wyoming President Ed Seidel will deliver the Department of Physics and Astronomy’s fall 2025 Rebka-Hafele-Einstein Distinguished Lecture Friday, Nov. 7.

“It has been suggested that the universe could be simulated,” said Dr. Faizal in a statement. “If such a simulation were ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

Albert Einstein, the man who reshaped our understanding of the universe, had a surprising piece of advice for parents. He ...
