Reconciling quantum mechanics with general relativity is a major challenge in theoretical physics and has been the subject of significant research efforts. However, it is difficult to quantify the exact amount of effort or allocate a specific fraction of time dedicated to this specific problem, especially in terms of a particular institution like CERN.
CERN (the European Organization for Nuclear Research) is primarily focused on high-energy particle physics and operates the Large Hadron Collider (LHC), which is used to conduct experiments in particle physics. While the LHC is not specifically designed to directly address the reconciliation of quantum mechanics and general relativity, it does provide valuable data that can contribute to our understanding of fundamental physics.
Efforts to reconcile quantum mechanics and general relativity have been pursued by various research institutions, universities, and individual physicists worldwide. These efforts involve theoretical investigations, mathematical modeling, and experimental tests. Theoretical physicists work on developing frameworks like quantum field theory, string theory, or loop quantum gravity, which aim to incorporate both quantum mechanics and general relativity into a unified theory.
It is important to note that reconciling these two fundamental theories is a complex and ongoing endeavor, with many different approaches being explored. It is not possible to accurately quantify the specific fraction of time or effort dedicated to this specific problem, as it varies among researchers, institutions, and even within the broader scientific community.
While CERN and other research institutions contribute to the broader understanding of fundamental physics, including the interplay between quantum mechanics and general relativity, it is difficult to attribute a specific fraction of their time solely to this specific endeavor. The pursuit of a unified theory that combines quantum mechanics and general relativity is a long-term and multifaceted goal that involves the collective efforts of physicists worldwide.
