Answer

The current consensus among cosmologists for the increasing rate of expansion of the Universe is primarily attributed to dark energy. Dark energy is a mysterious form of energy that makes up approximately 68% of the Universe and is believed to be responsible for the observed acceleration in its expansion. This phenomenon was first discovered through observations of distant supernovae and has since been supported by various cosmological data.
