New observations from the Dark Energy Spectroscopic Instrument are challenging the standard Lambda-CDM model of cosmology. A recent, still-unpublished hypothesis suggests that space itself may behave like a slightly viscous or “sticky” fluid, subtly affecting how the universe expands. By introducing a ghostly resistance to cosmic growth, the model could reconcile …​New observations from the Dark Energy Spectroscopic Instrument are challenging the standard Lambda-CDM model of cosmology.
