Despite soaring progress, scientists at AI’s largest gathering say key questions about how models work and how to measure ...
The Hubble tension is especially troubling because it involves two sets of measurements that offer conflicting views of the ...
New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...
Neutrinos are low-mass subatomic particles with zero electric charge that interact with matter only via the weak nuclear force and gravity. This makes neutrinos difficult to detect, despite the fact ...
From a particle smasher encircling the moon to an “impossible” laser, five scientists reveal the experiments they would run ...
Current physics is speeding toward a breaking point, as astronomers confirm that the Hubble tension in new data.

New cosmic lensing test sharpens the Hubble tension and hints at new physics
It’s a powerful technique, but small uncertainties at each step can add up, something critics argue may be behind the Hubble ...
The JGU team repeated the measurement but changed the beam energy and scattering angle, two variables that influence how the ...
A joint effort between two of the world’s largest neutrino experiments has brought scientists closer to understanding how the ...
A team of astronomers using a variety of ground and space-based telescopes including the W. M. Keck Observatory on Maunakea, ...
Scientists fear warming is driving a collapse in the ocean currents that shape climate far and wide. The ice-choked waters ...
