The cosmological constant might not be constant, and neither is baby talk

By: Nathaniel Tok SFU physics study questions cosmological constant SFU physicist Levon Pogosian has shown that dark energy might not be considered the cosmological constant through an international study on dark energy that he co-led. Dark energy is the energy of empty space that makes up most of the universe. The study, published in Nature Astronomy, documents data collected by the researchers as they studied dark energy density over time. Before this study, it was believed that dark energy did not change. However, the study’s results suggest that dark energy density might have increased over time. This finding runs contrary…
