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

Measurements in physics are funny things. You’d hope that attempts to quantify some of the fundamental properties of the Universe would follow a simple pattern ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...

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 ...

There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and ...
