A lot of stuff in cosmology about the curvature of the universe, dark energy, expansion. Some of the quarks were not observed until after. Observation with high beam neutrinos. Controllable quantum systems were barely imagined in 84, and now they are "common" and we might even be able to scale them to sizes necessary for quantum computing in the next decade.
