  • Thought experiment, combining starships, planets, general relativity and quantum mechanics, sheds light on new property of time.
  • Physicists conducted a Gedanken experiment, examining what a clock would measure if it was influenced by a massive object in quantum superposition.
  • The conclusion is that the flow of time doesn’t always linearly go forward -- cause and effect can coexist both in the forward and backward direction.
  • This is one of the first experiments illustrating the quantum properties of time.
