Both of those are things that are not revolutionary, but rather logical extensions of what the established models already predict. The Higgs boson was a direct confirmation of what is literally called the "standard model" of particle physics, and gravitational waves follow fairly directly from orbital decay + conservation of energy. Actually detecting them is a fairly impressive feat of engineering, but scientifically it's "yep, the thing we figured was probably true turned out to be true".
