Quantum cosmology seeks to apply quantum principles to the Universe as a whole, treating spacetime geometry and matter fields within a unified quantum framework. Central to this endeavour is the ...

Physicist Sean Carroll explores some of the deepest mysteries in quantum mechanics: the famous double-slit experiment, wave ...

Gravitational wave cosmology exploits the ripples in spacetime emitted by compact binaries as “standard sirens” to map the expansion history of the Universe and to probe the fundamental nature of ...

The first direct detection of gravitational waves was made by LIGO observatory in 2015. These waves were produced by the collision of two black holes, and therefore allow us to probe one of the most ...
