As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s not how it works. Hint: space-time is involved.

The speed of light is the fastest anything can travel. What happens to a photon from a galaxy 25 million light years away on its journey toward Earth?

Some of the earliest galaxies found with JWST are also the brightest. That’s a problem for our ideas about the universe.

Quantum information theory is the field behind quantum computing, but experts in this field are also applying their way of thinking to some big questions in quantum physics.

In trying to solve the ultimate problem, we may have inadvertently created a monster.

Quantum computing has huge promise from a technical perspective, but the practical benefits are less clear.

The pros and pitfalls of this type of thinking

The nature of dark energy remains one of the biggest puzzles in cosmology.

Pictures of black holes have a white outline around them when photographed, due to one of black holes’ unique and key features.

The discussions in the committee are always open, frank and sometimes emotional, but never hostile.
