Understand

Pixelated dark energy is a string theory scenario with a quantum mechanically stable cosmological constant.

The number of pixels that make up the universe slowly increases, manifesting as a time-dependent source of dark energy.
DESI has recently reported evidence for dynamical dark energy that fits within this framework.
In light of this, we perform the first cosmological analysis of the pixelated model.
