If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts ...

Quantum entanglement and being a twin inspires Marina Kappos's interest in frequency, resonance, and connections.

Staring up at the night sky, you might see thousands of stars sprinkled above the horizon. It feels as though you can see so ...

From unifying quantum physics and gravity to working out what is dark matter, the universe has some deep questions that ...

What exists at the core of a black hole? A research team led by Enrico Rinaldi, a physicist at the University of Michigan, ...

The image of the tiny flapping butterfly has come to stand for the outsized impact of small actions, or even the inherent unpredictability of life itself. But what was Lorenz – who is now remembered ...

The role of electrons and their negative charge in electric current is well established. Electrons also exhibit other ...

A new way to measure the temperatures of objects by studying the effect of their black-body radiation on Rydberg atoms has ...

Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...

Researchers are exploring multi-level atomic interactions to enhance quantum entanglement. Using metastable states in strontium, they demonstrate how photon exchange can sustain correlations, offering ...

Some 40 years earlier in 1842 the Austrian physicist Christian Doppler had discovered what is now called the Doppler effect. This is the theory that sound waves will change in pitch when there is a ...
