How does a photon/wave know to go around the sun rather than straight through it's gravity well?
-------------------------------------------------------
answers:
drake say: How does a photon curving around the sun prove there’s a gravity well there? Doesn’t it just prove there is gravity? Before Einstein proved curved space, if this phenomena were detected, wouldn’t anyone just assume it’s normal? How could they infer its warped space? Wouldn’t it take the field equations?

goring say: If a photon has no mass or volume it can never never go down a gravity well.
Gravity is caused by the compression of space at the edge of the gravity boundary of the universe.
Space has been very misconstrued.Space during the creation of universe was structured a a particular type of massive fluid.
Hence space exist as a structure as was indicated in the Biblical record of Creation.

CarolOklaNola say: Photons don't make conscious decisions. They are NOT sentient. The photon's trajectory may be changed by a star's gravity, but it also may go into the gravity well. It gets absorbed by the Sun or star.
Photons definitely DO exist, but they can be absorbed and destroyed.

Jeffrey K say: The photon does go thru the Sun's gravity well. It follows a geodesic in the curved spacetime.

Stuart say: What has this to do with string theory? There isn't a single string theory, but rather a family of them. String theory proponents believe that QFT is the low energy limit of a more general string theory, just as Newtonian Gravity is a low energy approximation of General Relativity. So far all of the string theories offer appealing mathematical elegance, but they don't actually make any predictions that could be falsified. As such the jury is well and truly out on whether they offer any better answers than QFT does, which is at least consistent with General Relativity.
Bottom line: light is certainly a wave and it has particle-like interactions with matter, but those may simply be features of the underlying waves

say: the photon was going through airport security , the TSA agent asked him if he had any luggage . the photon said " no , i'm traveling light " .
-
say: know? Waves spread out and so do photons, the gravity of a star is far too weak to stop it.
