Quantum Mechanics Shatters Classical Physics and Local Realism
Laboratory experiments in quantum physics demonstrate that the natural world operates outside the boundaries of classical locality and realism. Local physics assumes that no signal or influence can travel faster than the speed of light, yet quantum mechanics forces scientists to abandon the long-held image of the universe as a collection of independent, isolated pieces.
Realism fares no better under rigorous testing. Physics cannot assume that the properties of an object exist in a fixed, predetermined state before someone actually measures them. While these concepts sound abstract, they form the precise mathematical foundation behind everyday technology, including the transistors inside smartphones and lasers.
Mapping the Limits of Calculation in Barcelona
Theoretical physicist Gemma de les Coves investigates the fundamental limits of calculation, description, and comprehension at Universitat Pompeu Fabra in Barcelona. Working as an ICREA research professor, she examines how quantum mechanics challenges classical logic and forces a complete revision of how humans understand the physical universe.
Born in Barcelona in 1984, de les Coves approaches her research by looking at the intersections of logic, paradox, and self-reference. Rather than treating quantum phenomena as impenetrable mysteries, she studies the strict mathematical rules that govern microscopic reality and why macroscopic intuition fails when applied to electrons and black holes.

Two Radically Incompatible Interpretations
Modern physics offers two main frameworks for interpreting quantum strangeness, though neither provides a complete, comfortable picture for researchers. The first interpretation posits that superpositions are entirely real, meaning the universe constantly branches into separate, inaccessible universes for every possible outcome in a vast multiversal structure.
The second interpretation maintains that a single universe exists, but objects possess no objective properties of their own. Instead, everything remains strictly relational, with an object’s physical state depending entirely upon its interaction or observation by another system.
De Les Coves Examines Self-Reference and Logical Paradoxes
Beyond quantum mechanics, de les Coves focuses her academic inquiry on the paradoxes of self-reference and logical negation. Self-referential statements—such as declaring a sentence false within its own framework—create unresolvable loops that destabilize traditional logic and lead directly to undecidability problems in mathematics and computation.
These logical paradoxes extend into physical theory when examining concepts like causality and time travel. Researchers investigate whether physical reality actively forbids contradictions, making logical coherence not just a rule for human thought, but an absolute structural restriction on what can physically exist in the universe.
Reconnecting Exact Science with the Humanities
Reflecting on her career path, de les Coves notes an initial obsession with universal physical laws that led her to dismiss literature as too provincial. Over time, she recognized that scientific frameworks often overlook the immediate, singular reality of human existence within a specific time and place.
Today, she advocates for a closer dialogue between the exact sciences and the humanities. While scientists rely on human values and perspective to guide their inquiries, humanists benefit from understanding that physics is not a cold, arrogant discipline, but an active exploration into the true nature of time, matter, and the cosmos.
