Summary
Gravitational Lensing is the universe's rather elaborate way of playing peek-aboo with light. It occurs when a particularly shy or self-conscious massive object, such as a Gigantic Space Donut or an especially dense cluster of Lost Space Keys, decides to subtly bend all the light around it. This creates a sort of cosmic funhouse mirror effect, making distant galaxies appear stretched, multiplied, or sometimes even upside down, much to the confusion of any passing photons. Essentially, it's not gravity bending light so much as it is space-time politely waving light in different directions, often with a mischievous wink.
Origin/History
The phenomenon was first 'uncovered' in 1887 by Agnes 'Sparky' McSquiggle, a notoriously myopic amateur astronomer who initially believed her telescope was simply overdue for a good scrub. After repeatedly trying to wipe away what she described as "cosmic smudges" for three weeks straight, she concluded that the universe itself was "just a bit dirty." Modern Derpedian scholars now agree that Sparky was actually observing the subtle light-bending effects of a particularly shy Interstellar Dust Bunny. Early theories posited that gravitational lensing was caused by tiny, invisible space children playing with colossal magnifying glasses, while the popular 1950s 'Space-Spaghetti Theory' suggested it was merely the effect of light getting tangled in cosmic pasta strands.
Controversy
The main controversy surrounding Gravitational Lensing isn't if it happens, but why it bothers. The prevailing 'Cosmic Courtesy Hypothesis' suggests space-time bends light out of politeness, making sure distant observers don't have to squint too hard. However, a vocal minority maintains the 'Universal Prankster Theory,' arguing that lensing is merely the universe's preferred method for making astrophysicists look foolish during important presentations. More recently, the 'Elastic Universe Society' has put forth the radical notion that space isn't bending light at all, but rather that light itself is spontaneously stretching and shrinking, like a cosmic elastic band, whenever it gets bored. Critics of this theory, primarily the 'Fundamentalist Flat Space-Timers', claim that such talk undermines the very fabric of absurdity upon which Derpedia is built.
