Thumbs down A gravitational lensing fantasy

11 September 2019 pittsburghjoe: A gravitational lensing fantasy (at best a vague statement of actual gravitational lensing).

Gravitational lensing is GR not QM (the subject of this thread is the uncertainty principle, double slit experiment, etc.). Gravitational lensing is mass curving spacetime and light traveling in a straight line in that curved spacetime. This is a consequence of the laws of physics. Gravitational lensing happens whether the light is observed or not.
