Nowadays, we have an outstanding grasp of gauge theories on both experimental and theoretical fronts. Meanwhile, our understanding of gravitational physics has advanced greatly, but many mysteries remain in part due to its highly non-linear nature and non-renormalizable interactions. In this talk, I will show how to use our insights on gauge theories to advance our comprehension of gravity. This will be pursued via the double copy, also known by the slogan: gravity=(Yang-Mills)^2. The double copy gives us a technique to simplify gravitational calculations (like those for gravitational waves), but also a deep insight into the structure of gravity. I will show how this idea is applicable beyond its original incarnation and will focus on three interconnected examples: exact classical solutions (such as black holes), 3-dimensional spacetimes, and massive theories.  Last, I will comment on how these examples can teach us about physics in curved spacetimes.
