World's heaviest Schrödinger's cat made in quantum crystal visible to the naked eyePhysicists have placed part of a sapphire crystal into a quantum superposition, making it the heaviest object to show quantum effects, in a new take on Erwin Schrödinger's famous cat experiment.

Does reality exist when we're not looking?In quantum physics, particles exist in many states at once until you measure them. Can reality really work that way?
-
Do quantum universes really exist?In some interpretations of quantum mechanics, such as the Many-Worlds interpretation or the Pilot Wave Theory, parallel universes may form every time a subatomic particle goes through any interaction.
