And that's why light changes path under the influence of gravity.
This totally disproves the theory of general relativity, based on the assumption that spacetime is curved, which has never been proven experimentally.
Thoughts?

>> No.15196639

Do you agree with the fact that proving photons have mass would disprove every part of general relativity theory that doesn't simply work as a model by mathematical coincidence?

>> No.15196644

If photons have no mass thus no energy according to Einstein, how is it possible to realize devices like optical tweezers and to push objects (solar sails) by using photons?

>> No.15196692

Also it is commonly believed in physics that the speed of light slows down if light passes through a medium, but this has no explaination except the interaction of the photon's mass with matter!
The wave-particle duality doesn't actually exist, it is an error of interpretation based on the interaction of electric fields generated by the photon itself (and other particles)!

15196745

the official explaination is literally circular reasoning based on two assumptions:

1) c is the speed of light because photon mass is 0 and nothing can go faster than light
2) thus the mass of the photon is 0

I can imagine a perfectly reasonable explaination to why the Sun is able to bend light, without spacetime bullshit:
Because, photons have mass and as every object whose mass is not zero (even if really small), they are gravitationally shifted by the Sun's huge mass and gravity field.

>> No.15196787

>>15196773
>i think it might have to do with the mass of the medium that light travels through
ALSO A POSSIBILITY!
what if photons are bent by passing near the Sun due to refraction by hot hydrogen or plasma?
Did anyone think of this? It would be 10000 times more reasonable than the spacetime theory.

You are mixing things up here.
There are two states of basic substance, energy (photons) and matter (particles), both are interchangeable, but both are on different status. And this only applies on EM forces, since other fields have different kinds of matter/energy configurations.
The process of how energy become particles isn't well known, but of course is related with some sort of thresholds.
But then again, particles can change their speed, because they have mass, once you don't have mass your speed will be always c. And this have been constantly observed on photons (don't get confused with some experiments dealing with interference... that's another issue)
