Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

Astronomers have discovered a black hole in the early universe, ID830, growing thirteen times faster than physics allows, defying cosmic rules and challenging long-held theories of black hole ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

On Thursday, February 6, 2025, Professor Jamie Nagle captivated an audience of students, staff, faculty, and community members during the 125 th Distinguished Research Lecture hosted by CU Boulder’s ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science ...

The “horizon” he points to isn’t a doorway to the divine, other scientists say. Yet, modern physics has been trying to answer questions once left to religion.
