Universe’s expansion might be slowing down, not speeding up
Hey, Space Placers! Researchers used Type Ia supernovas , similar to SN1994d (pictured above in its host galaxy NGC4526), to help establish that the universe’s expansion may actually have started to slow. For decades, scientists have believed the universe’s expansion was accelerating. The new research upends that paradigm. Image via NASA/ ESA/ RAS ( CC BY 4.0 ). The latest research and related paper. As more data comes in from on going surveys and research we may be closing in on an answer. Sky Guy in VA
