Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
Albert Einstein, Boris Podolsky, Nathan Rosen
Overview
The 'EPR paradox' argued that quantum mechanics, if taken as complete, implies a spooky instantaneous link between distant particles. Einstein, Podolsky and Rosen used this to claim the theory must be incomplete — that hidden variables underlie its probabilities.
Framed the entanglement debate that became the foundation of quantum information science.
Key findings
Methods
A purely theoretical gedanken-experiment using a two-particle wavefunction with correlated positions and momenta, combined with a philosophical criterion for when a physical quantity counts as objectively real.

On the Einstein Podolsky Rosen Paradox
Bell turned the EPR debate from philosophy into experiment. He proved that any theory based on local hidden variables must obey an inequality that quantum mechanics violates — making the question of non-locality empirically decidable.

Observation of Gravitational Waves from a Binary Black Hole Merger
The first direct detection of gravitational waves, a century after Einstein predicted them. On 14 September 2015 the two LIGO detectors recorded the spacetime ripple (event GW150914) from two black holes spiralling together and merging over a billion light-years away.

Broken Symmetries and the Masses of Gauge Bosons
Higgs showed how gauge bosons — the carriers of fundamental forces — can acquire mass through spontaneous symmetry breaking without spoiling the underlying gauge symmetry. The mechanism predicts a new scalar field and its associated particle.
