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 ...
Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...
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 ...
Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...

The most energy efficient reactions in physics, according to scientists
Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...
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, ...
