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 ...

Gravitational wave cosmology has emerged as a transformative approach to probing the early universe, supplementing traditional electromagnetic observations with ripples in spacetime generated by ...

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 ...
