I just recently watched a video where they were explaining the double slit experiment. I understand that the interference pattern would be observed if you send photons or electrons one after the other. The conclusion that the author seems to make is that it is as though the particle/packet of energy travels through both the slits after somehow splitting into two. Has anyone done an experiment whe…

Quantum theory says a vacuum isn’t truly empty, but proving it directly has remained out of reach. A new experiment using immensely powerful lasers could finally expose its hidden structure – and perhaps offer clues to dark matter

This technical treatise establishes the unified mathematical extension of the Primary Logical Infrastructure (PLI) framework (Sottosanti, 2026). By mapping the continuous spacetime manifold onto a discrete, graph-theoretical matrix (G_p), the analytical and physical breakdowns of orthodox continuous physics are systematically regularized. First, bridging the author's foundational work on syntacti…

Early quantum mechanics can, in a precise sense, be read as a theory of time. A Lorentz transformation turns spatially homogeneous proper periodicity into a spacetime phase wave; de Broglie’s relation between rest energy and proper frequency then yields λ=h/p, while global phase consistency leads to the quantization of closed structures. This derivation motivates the concept of event latency: the…

MIT researchers find that recoil and neutrinos’ fermionic nature prevent the quantum amplification needed to produce a directional neutrino laser beam. A proposed technology for generating laser-like beams of neutrinos has been ruled out by MIT researchers, who found that two fundamental quantum effects prevent the concept from working. The findings close off a theoretically […]

I am recently studying bosonization. In "the yellow book" by Philippe Di Francesco, Pierre Mathieu, and David Sénéchal, they calculated the partition function of a compactified boson using the path integral method. For each winding configuration $\phi(z+1,\bar z+1)=\phi(z,\bar z)+2\pi nR$ and $\phi(z+\tau,\bar z+\bar\tau)=\phi(z,\bar z)+2\pi wR$ (where we identified the torus as $\mathbb{T}^2\con…

What quantum physics(randomness) tells about our reality? everything is random, there is no cause-effect world?

A Programmer’s Guide to Building the Right Oracle Most quantum speedup claims depend on an oracle that exists only on paper. This course teaches the craft of building practical quantum circuits from scratch. Choose the problem, build the oracle 1. A different computer - CPU, GPU, QPU: three devices, three workloads - the QPU’s job: fewer samples for an average - three questions: task randomness…

Scientists have observed a long-predicted effect of gravity on a falling quantum object for the first time. The experiment suggests that a key principle in Albert Einstein’s theory of gravity also applies to matter governed by the strange rules of quantum physics. The international study, which included Nobel Prize-winning physicist Professor Sir Roger Penrose, was […] The post Scientists See Ein…

Researchers have found a way to create a complete 3D image of a molecule’s wavefunction, one of quantum mechanics’ most fundamental yet elusive features.
