Wandering Space Rocks Help Solve Mysteries of Planet Formation
After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.
How (Relatively) Simple Symmetries Underlie Our Expanding Universe
Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.
The Quantum Theory That Peels Away the Mystery of Measurement
A recent test has confirmed the predictions of quantum trajectory theory.
How to Understand the Universe When You’re Stuck Inside of It
Lee Smolin’s radical idea to reimagine how we view the universe.
The Simple Idea Behind Einstein’s Greatest Discoveries
Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.
Philosophers Debate New ‘Sonic Black Hole’ Discovery
Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
When Magic Is Seen in Twisted Graphene, That’s a Moiré
What do moiré patterns seen in optics, art, photography and color printing have to do with superconducting layers of graphene?
How to Turn a Quantum Computer Into the Ultimate Randomness Generator
Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
A New Law to Describe Quantum Computing’s Rise?
Neven’s law states that quantum computers are improving at a “doubly exponential” rate. If it holds, quantum supremacy is around the corner.
