A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. The discrepancy is tiny, but for one of nature’s most…

Einstein’s “spooky action” just survived one of physics’ most extreme tests

https://www.sciencedaily.com/releases/2026/09/260919031023.htm

Physicists have detected strong evidence that heavy, fleeting Z bosons can become quantum entangled during Higgs boson decays at CERN’s Large Hadron Collider. The result shows that Einstein’s “spooky action at a distance” survives even under some of the…

Scientists are about to test Einstein’s gravity with exotic matter

https://www.sciencedaily.com/releases/2026/09/260918024808.htm

Scientists have found a new way to create a controlled beam of muonium, an exotic atom containing a heavier cousin of the electron. The advance could allow researchers to test for the first time whether gravity acts on second-generation particles exactly…

A $100 detector can see invisible particles raining down from space

https://www.sciencedaily.com/releases/2026/09/260917003725.htm

A pocket-sized, roughly $100 detector can reveal the invisible stream of cosmic particles constantly passing through Earth and even through our bodies. What began as a student physics project is now being used in major experiments, balloon missions, and…

Physicists can’t agree on how the Universe works

https://www.sciencedaily.com/releases/2026/09/260912220041.htm

A massive worldwide survey of physicists has revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum…

Scientists are building a microscope powered by a quantum computer

https://www.sciencedaily.com/releases/2026/09/260912220038.htm

Scientists are combining an electron microscope with a quantum computer to squeeze far more information from each electron. The approach could reveal faint details with fewer electrons, helping protect fragile samples that conventional microscopy can…

CERN finds gluons behaving strangely deep inside atomic nuclei

https://www.sciencedaily.com/releases/2026/09/260911214303.htm

Published: September 12, 2026 11:04

Physicists at CERN have found a new way to peer deep inside atomic nuclei and distinguish between two competing explanations for how gluons behave. Using the ALICE experiment at the Large Hadron Collider, researchers measured particle production at…

Tiny sound waves could help solve a major quantum computing problem

https://www.sciencedaily.com/releases/2026/09/260911214245.htm

Researchers at Harvard have demonstrated a way to protect quantum information using microscopic sound waves. By continuously surrounding a diamond-based qubit with mechanical vibrations, they extended its coherence time by roughly threefold. The same…

Physicists just found a tiny glitch in time itself

https://www.sciencedaily.com/releases/2026/09/260910225251.htm

Published: September 11, 2026 01:18

Unconventional quantum theories may imply that time itself has a tiny fundamental uncertainty, placing an ultimate limit on how precisely any clock could measure it. The effect is far beyond current detection, but it could reveal a hidden connection…

Scientists observe Einstein’s gravity in the quantum world for the first time

https://www.sciencedaily.com/releases/2026/09/260907201552.htm

Published: September 8, 2026 08:09

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s quantum wave so that one part was held in place while the…

A mysterious signal around Earth could be dark matter

https://www.sciencedaily.com/releases/2026/09/260904000328.htm

Published: September 5, 2026 20:58

Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark photon…
