When two black holes merge, they emit gravitational waves that race through space and time at the speed of light. When these reach Earth, large detectors in the United States (LIGO), Italy (Virgo) and Japan (KAGRA) can detect ...
By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists from Friedrich-Alexander-Universität Erlangen-Nürnberg ...
To sit under the vast expanse of stars is to imagine swimming across shining, stellar rivers, creeks and tributaries. But to sit here also is to feel that lump in your throat and skip in your heart, realizing everything you ...
Recently-published research from an international team of physicists reveals how the three-dimensional shape of rigid microscopic filaments determines their dynamics when suspended in water, and how control of that shape ...
Physicists believe most of the matter in the universe is made up of an invisible substance that we only know about by its indirect effects on the stars and galaxies we can see.
Quantum theory, which was formulated in the first three decades of the twentieth century, describes a wide array of phenomena at the molecular, atomic and subatomic scales. Among its many technological applications, three ...
Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity come in tiny, quantized packets ...
For millennia, humans have been fascinated by the mysteries of the cosmos.
When it comes to studying particles in motion, experimentalists have followed a 100-year-old theory that claims the microscopic motion of a particle is determined by random collisions with molecules of the surrounding medium, ...
What exactly is light—and what is it made of? It's an age-old question that dates back to antiquity, and one of the most important investigations undertaken by scientists looking to understand the nature of reality.
