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.

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

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 ...

Steam Next Fest spotlights seven indie demos; highlights include Paperhead, built over 9 years by one developer, plus Replaced and Wind Rose.

We backed the Iran nuclear deal not out of trust in Tehran but trust in physics. A decade later, Iran’s program is stronger, and the cost of abandoning diplomacy is clear.

U of A alumnus Alex O'Brien now operates a multi-ton-per-year production facility, running pilot programs with the enhanced nickel superalloys he spent his Ph.D. developing.

When private companies develop and sell solar geoengineering technologies, they draw a proprietary curtain over a planetary matter. If countries want to pursue the public good, international ...

Historically, cosmological models rely on "free parameters"—arbitrary, human-tuned variables inserted into the math to force the formulas to match reality. Kulkarni's updated simulation completely ...

Each year, after the CBSE Physics board examination, a familiar remark echoes through classrooms and staff rooms: “The numericals were not difficult, but they were confusing.” This confusion is not ...
