Dark energy may have once been ‘springier’ than it is today − DESI cosmologists explain what their collaboration’s new measurement says about the universe’s history
Dark energy may have once been ‘springier’ than it is today − DESI cosmologists explain what their collaboration’s new measurement says about the universe’s history Dark energy measurements from the DESI collaboration suggest that the universe was expanding slightly faster a few billion years ago than it is today, implying that dark energy’s “springiness” was […]

NASA Aims to Fly First Quantum Sensor for Gravity Measurements
NASA Aims to Fly First Quantum Sensor for Gravity Measurements NASA is developing the first space-based quantum sensor for measuring gravity, which will enable groundbreaking observations of Earth’s gravitational field and beyond. The Quantum Gravity Gradiometer Pathfinder (QGGPf) instrument will use two clouds of ultra-cold rubidium atoms as test masses to measure differences in gravitational […]
