Sagittarius A-Star replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.I think this is called spontaneous symmetry breaking. -
Sagittarius A-Star replied to the thread Space Stuff and Launch Info.The Fench/German/Japanese rover Idefix will explore the surface of Phobos before the MMX spacecraft lands. -
Sagittarius A-Star replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.Yes, but the initial condition of the system is not symmetric, because one side is up before the coin is thrown. There exists a... -
Sagittarius A-Star replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.Please consider a 1 photon double-slit experiment, which is symmetric regarding left/right. If a photon is detected on the left side of... -

Goethe (actually not Goethe, that’s a loose paraphrase from an English language translation) has a good point but you’ve misunderstood... -
Sagittarius A-Star replied to the thread Undergrad Problem in understanding how upwards acceleration works (General Relativity).No. Both, plus calculating to solve problems, are needed for successful lerning. -

This involves analytic continuation of the time coordinate, which the OP rules out, so it's not what's being asked about in this thread... -
