High-energy & quantum cosmology
Vacuum Energy
The energy that fills empty space even in the absence of matter or radiation, arising from quantum fields in their lowest state. Vacuum energy is a leading candidate for the dark energy driving cosmic acceleration and is closely tied to the cosmological constant in Einstein's equations.
