- Physics
In a first, Galileo’s gravity experiment is re-created in space
A key principle of general relativity holds up in a new space-based test.
- Physics
Collision illuminates the mysterious makeup of neutron stars
Scientists size up neutron stars using gravitational waves and light.
- Quantum Physics
‘Arrow of time’ reversed in quantum experiment
In quantum systems, heat can flow “backward,” from cold to hot.
- Particle Physics
Excess antielectrons aren’t from nearby dead stars, study says
Pulsars might not be behind excess antimatter, gamma-ray observations suggest.
- Physics
Colliding black holes are reported for a fifth time
LIGO spots another merger, this time with less fanfare.
- Cosmology
Simulating the universe using Einstein’s theory of gravity may solve cosmic puzzles
Better simulating the dense parts of the universe could improve scientists’ view of how the universe evolves.
- Physics
Why the wiggle in a crowd’s walk can put a wobble in a bridge
New simulations can better predict when pedestrians cause a bridge to shimmy.
- Quantum Physics
Quantum computers take a step forward with a 50-qubit prototype
Race to build ever-more-powerful processors edges the technology closer to being able to best traditional machines.
- Quantum Physics
Quantum computing steps forward with 50-qubit prototype
Bit by qubit, scientists are edging closer to the realm where quantum computers will reign supreme.
- Physics
Photons are caught behaving like superconducting electrons
Light particles, or photons, swap energy like electrons in a superconductor.
- Quantum Physics
Light’s weird dual nature weathers trip to space and back
“Delayed-choice” experiment performed in space reaffirms the idea that light can behave like a wave or a particle.
- Astronomy
Neutron star collision showers the universe with a wealth of discoveries
A collision of neutron stars was spotted with gravitational waves for the first time. Telescopes captured gamma rays, visible light and more from the smashup.
