Quantum paradox points to shaky foundations of reality

Nearly 60 years ago, the Nobel prize–winning physicist Eugene Wigner captured one of the many oddities of quantum mechanics in a thought experiment. He imagined a friend of his, sealed in a lab, measuring a particle such as an atom while Wigner stood outside. Quantum mechanics famously allows particles to occupy many locations at once—a Read more about Quantum paradox points to shaky foundations of reality[…]

Experiment confirms 50-year-old theory describing how black holes could generate energy

In 1969, British physicist Roger Penrose suggested that energy could be generated by lowering an object into the black hole’s ergosphere—the outer layer of the black hole’s event horizon, where an object would have to move faster than the speed of light in order to remain still. Penrose predicted that the object would acquire a Read more about Experiment confirms 50-year-old theory describing how black holes could generate energy[…]
