In 1917 Einstein applied general relativity to a static universe, introducing the cosmological constant to address gravitational collapse. He resisted expanding universe views despite contemporary suggestions from astrophysicists Alexander Friedman and Georges Lemaître.
Great tits can recall the location of cached food hideaways after one or 24 hours, according to a Swedish study published in Behavioral Ecology and Sociobiology. This observational spatial learning ability may be more crucial for non-hoarders like great tits, as it helps them survive during harsh weather conditions.
Researchers propose that a 33 A.D. Old Jerusalem earthquake triggered neutron radiation, causing the Shroud's distinctive image and potentially leading to incorrect radiocarbon dating results. The theory is based on piezonuclear fission reactions and suggests that neutron emissions from earthquakes could have imprinted the image onto t...
