What role do the Einstein field equations play in simulating extreme spacetime lensing?
They explain how light is emitted by black holes during lensing events.
They describe how matter and energy curve spacetime, determining how light paths bend around massive objects.
They provide a quantum mechanical description of light particles near massive objects.

What is the primary reason gravitational lensing is more complex near extreme spacetimes like black holes compared to less massive objects?
Because black holes emit strong light that interferes with the lensing effect.
Because gravitational lensing only occurs in the presence of electromagnetic forces, which are stronger near black holes.
Because the intense curvature of spacetime near black holes causes light to follow highly curved and multiple paths, creating complex lensing patterns.
