A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a kind of quantum instability that could trigger what's known as vacuum decay ...

Electrons can be "kicked across" solar materials at almost the fastest speed nature allows, scientists have discovered, ...

Dark matter is one of the biggest mysteries in science. Astronomers believe it makes up most of the matter in the universe, yet no one has ever directly seen it. It does not reflect, emit, or absorb ...

Most of us can relate to being worried about inflation: we are all concerned about the cost of living and what our political leaders are doing to address it. Sometimes, I have to remind myself that we ...

The surprising detection of light 200 times more powerful than previous observations from the nearby pulsar Vela indicates hidden physics around dead stars. When you purchase through links on our site ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process produces per unit of fuel, physicists often compare how much of a substance’s ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

Jarred Roberts receives funding from NASA. My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, ...
