The normal diagram used to explain gravitational lensing shows a two-dimensional plane that is deflected by a heavy weight. This is a two dimensional description that requires an extra dimension to complete it. My question is does real three dimensional space require an extra dimension to explain gravitational lensing. I know that time is somehow involved but surely a spacial dimension would be required.

    I would recommend going through a traditional GR course, which should be clear. There are many other questions on phys.SE on gravitational lensing and so this seems to be redundant. – VaibhavK Feb 19 '24 at 12:36
  • Can you post an example of a diagram showing a " two dimensional plane that is deflected by a heavy weight"? – KDP Feb 19 '24 at 15:25
  • As soon as we learned from GR that a gravitational body can bend light paths, gravitational lensing automatically follows as a corollary. Where is the conceptual difficulty? – KDP Feb 19 '24 at 15:33
