Einstein's abandoned cosmological constant returns to explain the universe's accelerating expansion
Reported byScienceDaily ↗·Sourced by Goodlede
Physicists describe how Einstein's 1917 cosmological constant—which he abandoned as his 'greatest blunder'—became central to modern cosmology after 1998 observations revealed the universe's expansion is accelerating rather than slowing. The constant now underpins the current best cosmological model, though questions remain about whether even this successful picture may ultimately be incomplete.
