Einstein's Theory Has a Problem -- This Idea Solves It

TL;DR

A new paper proposes space is one-dimensional at short distances, potentially solving quantum gravity's infinity problem while maintaining valid probabilities (unitarity).

Key Points

• 1.Einstein's gravity resists quantization because standard math produces infinities. Decades of attempts since the 1930s have failed, spawning alternatives like string theory, loop quantum gravity, and causal dynamical triangulations.
• 2.The proposed solution: space is effectively one-dimensional at very short distances. Most quantum gravity approaches independently converge on this — strings and loops are 1D objects, and spectral dimension analysis shows spacetime behaves fractally near the Planck scale.
• 3.The new paper claims to fix the fatal flaw of earlier 1D-space models — broken unitarity. Previous attempts produced probabilities greater than one (mathematical nonsense); the authors now assert they can preserve unitarity, making quantum probabilities well-defined.
• 4.The theory scores 8/10 on the presenter's 'BS meter' because it is experimentally untestable. Observable quantum gravity effects are 40 orders of magnitude beyond current technology, raising the question of whether quantum gravity can ever be science rather than philosophy.
