Do you believe that lensing is from:
a) light being attracted to a planet's gravity.
b) light conforming to the shape of space which is distorted because of the planet's mass.
c) there is no such thing as lensing. it is an optical illusion.

The correct answer is B. From Einstein's theory of gravity, a mass distorts the space around it causing light that passes near it to travel in a different direction. So it acts like a lens that concentrates the light traveling passed it so you can see the farther object in a ring around the foreground object such as a planet or galaxy.

B. Light has no mass, so it is not subject to gravity. Gravity is a property of mass. Matter distorts the space around it, gives it a directional bias. The greater the mass, the stronger the bias. So the mass is not attracting the light but refracting it, just like a lens.

What people "believe" is irrelevant...gravitational lensing is fact. And B is the correct answer though Einsteinian wording always leaves me something to be desired.

B - it fits the results of scientific experimentation and what is actually seen through scientific observation.
