Alternative gravity theory offers possible explanation for dark energy changing over time
For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is thought to have behaved in the same way at every epoch.
