Evidence is growing that dark energy's influence on the expansion rate of the universe has been changing over time. A range of space and ground-based observatories are coming online to measure the expansion rate across the universe's history, but a supercomputer has crunched the data and found similar results. Researchers compared two large-scale simulations of the universe, one with constant dark energy and one where it varies, and that better matched the observations.
