The discovery that stuck - 20 years of graphene
Briefly

In 2004, physicists reported isolating ultrathin films of carbon atoms using sticky tape, discovering their remarkable properties that would revolutionize condensed-matter physics.
The discovery of atomically thin films of graphite demonstrated that they can exist and be stable at room temperature, challenging existing physics theorems.
Experimental evidence showed that graphene layers, contrary to quantum fluctuation theories, could exist and conduct electricity exceptionally well, opposing initial mathematical assumptions.
The report by Novoselov et al. in Science was monumental, confirming that real-world behaviors do not always conform to theoretical predictions, particularly in two dimensions.
