May 31, 2024 · Time Crystals. Time crystals are a phase of matter proposed theoretically by Nobel laureate Frank Wilczek in 2012 and subsequently created in the lab in 2016. In a conventional crystal like salt or quartz, atoms are arranged in a repeating pattern in space. Time crystals however exhibit a repeating pattern in time.

21 hours ago · The question whether information is truly lost in black holes (the black hole information paradox) has divided the theoretical physics community. In quantum mechanics, loss of information corresponds to the violation of a property called unitarity , and it has been argued that loss of unitarity would also imply violation of conservation of ...
21 hours ago · It is hard to determine an exact upper bound on the collective average mass of the three neutrinos. For example, if the average neutrino mass were over 50 eV/c 2 (less than 10 −5 of the mass of an electron), the universe would collapse. CMB data and other methods indicate that their average mass probably does not exceed 0.3 eV/c 2. Thus ...
