A discrepancy between mathematics and physics has plagued astrophysicists’ understanding of how supermassive black holes merge, but dark matter may have the answer.
Grasping the precise energy landscapes of quantum particles can significantly enhance the accuracy of computer simulations for material sciences. These simulations are instrumental in developing advanced materials for applications in physics, chemistry, and sustainable technologies. The research tackles longstanding questions from the 1980s, paving the way for breakthroughs across various scientific disciplines.
An international group of physicists, led by researchers at Trinity College Dublin, has developed new theorems in quantum mechanics that explain the “energy landscapes” of quantum particle collections. Their work resolves decades-old questions, paving the way for more accurate computer simulations of materials. This advancement could significantly aid scientists in designing materials poised to revolutionize green technologies.
The new theorems have just been published in the prominent journal Physical Review Letters. The results describe how the energy of systems of particles (such as atoms, molecules, and more exotic matter) changes when their magnetism and particle count change. Solving an open problem important to the simulation of matter using computers, this extends a series of landmark works commencing from the early 1980s.
Researchers at California State Polytechnic University (CalPoly), Pomona are carrying out a series of quantum physics experiments expected to provide strong scientific evidence that we live in a computer simulated virtual reality.
Devised by former NASA physicist Thomas Campbell, the five experiments are variations of the double-slit and delayed-choice quantum eraser experiments, which explore the conditions under which quantum objects ‘collapse’ from a probabilistic wavefunction to a defined particle. In line with the Copenhagen Interpretation of quantum mechanics, Campbell attributes a fundamental role to measurement, but extends it to human observers. In his view, quantum mechanics shows that the physical world is a virtual reality simulation that is computed for our consciousness on demand. In essence, what you do not see does not exist.
Campbell’s quantum experiments have been designed to reveal the interactive mechanism by which nature probabilistically generates our experience of the physical world. Herein, Campbell asserts that, like a videogame, the universe is generated as needed for the player and does not exist independent of observation.
While multiple quantum experiments have pointed to the probabilistic and informational nature of reality, Campbell’s experiments are the first to investigate the connection between consciousness and simulation theory. These experiments are based on Campbell’s paper ‘On Testing the Simulation Theory’ originally published in the International Journal of Quantum Foundations in 2017.
Paradigm-shifting consequences
Importantly, Campbell’s version of the simulation hypothesis differs from the ‘ancestor simulation’ thought experiment popularized by philosopher Dr. Nick Bostrom. “Contrary to what Bostrom postulates, the idea here is that consciousness is not a product of the simulation — it is fundamental to reality,” Campbell explains. “If all five experiments work as expected, this will challenge the conventional understanding of reality and uncover profound connections between consciousness and the cosmos.” The first experiment is currently being carried out by two independent teams of researchers — One at California State Polytechnic University (Pomona) headed by Dr. Farbod Khoshnoud, and the other at a top-tier Canadian university that has chosen to participate anonymously at this time.

Campbell will be joined by Donald Hoffman, Rizwan Virk, Stephan A. Schwartz and others for the Doorway to the Future Event in Huntsville, Alabama this September.
As public trust in science continues to wane, it is essential for scientists to demonstrate what science is — and what it is not — to everyone.
