We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These meth ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

The fragility and laws of quantum physics generally make the characterisation of quantum systems time-consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A ...
