Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as ...

The researchers state that the discovery of this extremely high-energy neutrino is the first concrete proof that the universe produces neutrinos at these incredible energy levels.

A deep-sea detector glimpsed a particle with 220 million billion electron volts of energy — around 20 times as energetic as any neutrino seen before.

William Matthaeus, the Martin A. Pomerantz Chair of Physics and Astronomy at the University of Delaware, has won UD’s highest faculty honor — the Francis Alison Award — in recognition of his ...

Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

You may not have heard of Ansys, but it's in the process of being acquired by chip design tool firm Synopsys for $35 billion.

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

The second law of thermodynamics, a cornerstone of modern physics, states that entropy—a measure of disorder—never spontaneously decreases. It governs everything from the efficiency of engines to the ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

For over a century, the Maxwell’s Demon paradox has haunted physics. This thought experiment suggests that a tiny, ...

Mathematical equations have shaped our understanding of the universe, and these nine have played a key role in changing the world.

It's only fitting that the company generating electricity by loop-de-looping a ground-tethered winged drone is from North ...
