Why modern physics is stuck and how thought experiments might finally break the deadlock
In short: For a century, physics has relied on two conflicting pillars: quantum mechanics and general relativity. While scientists chase decimal points, Vlatko Vedral argues we need a radical shift. By using innovative thought experiments to probe the interface between these theories, we may finally unlock a deeper, unified understanding of our reality.
For the past hundred years, the landscape of physics has been dominated by quantum mechanics and general relativity. Despite their individual successes, these two frameworks remain fundamentally at odds. Vlatko Vedral, a Professor of Quantum Information Science at the University of Oxford, suggests that the field has become stagnant, with many researchers merely refining existing data rather than seeking the profound, underlying explanations that define the nature of the universe.
The core of the problem lies in the stubborn classical nature of general relativity, which has resisted all attempts at quantization. Vedral’s work, detailed in his 2025 book Portals to a New Reality, focuses on using thought experiments to bridge this divide. These experiments aim to challenge our current grasp of space and time. By testing how quantum principles might alter the equivalence principle—a cornerstone of general relativity—physicists hope to see if one theory must be modified to accommodate the other.
Vedral’s approach is rooted in his extensive background in quantum information theory, entanglement, and thermodynamics, fields in which he has authored over 500 papers. His contributions were recognized in 2007 with the Royal Society Wolfson Research Merit Award. By pushing the boundaries of how we critique our best theories, Vedral believes we are on the brink of a new revolution. This shift is not just about technical adjustments; it is about fundamentally transforming our conceptual map of reality on both the smallest and largest scales.
Ultimately, the goal is to resolve the tension between the quantum and the classical worlds. Whether through exploring quantum computing or the mechanics of gravity, the objective remains the same: to move beyond the current impasse. As Vedral presented in his November 2025 lecture at the Royal Institution, the path forward requires us to rethink the very foundations of physics, potentially leading to a reality that looks very different from the one we currently describe.
