Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

It’s a powerful technique, but small uncertainties at each step can add up, something critics argue may be behind the Hubble ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

The image of this quasar is split into four by a massive galaxy acting as a gravitational lens. By analyzing slight delays in the light from these lensed quasars, astronomers arrived a new estimate of ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

Lake Shore Cryotronics’ M81-SSM offers DC, AC and lock-in source and measurement. Synchronous modularity The M81-SSM controller shown with two source modules (left); two measure modules (right); all ...
