IPI Talk - Tejinder Singh, Tata Institute of Fundamental Research, 8 Feb. 2025

Title: Do we live in a 6D space-time, and are the extra dimensions timelike?

Abstract:

The E8 x E8 octonionic theory of unification suggests that our universe is six dimensional and that the two extra dimensions are timelike. This in principle offers an explanation of the quantum nonlocality puzzle, also known as the EPR paradox. Quantum systems access all six dimensions whereas classical systems such as detectors experience only four dimensions. Therefore, correlated quantum events which are timelike separated in 6D can appear to be spacelike separated, and hence nonlocal, when projected to 4D. Our lack of awareness of the extra timelike dimensions creates the illusion of nonlocality whereas in reality the communication obeys special relativity and is local. In principle, this idea can be tested experimentally.

Meet Willow.

Willow is so fast that it seems to borrow processing power from parallel realities. Its work confirms the theory of the multiverse put forward by David Deutsch,” said Hartmut Neven, founder of Google Quantum AI.

IPI Poster presented at AAS 245

IPI member and researcher, Jose C. Gómez, presented a new Iposter at the prestigious AAS 245 Meeting. In this work, he continued exploring Structural Units (SU) with the aim of introducing their study to the scientific community. At the same time, Jose tried to explain them in an accessible way so that anyone with some knowledge of physics and mathematics can understand them.

The Iposter format allows for great versatility, so we invite you to navigate and interact with it through the various links included.

IPI lecture on 11th of Jan. 2025 - Clifford Ellgen on Particle Knots and Entropic Dynamics

IPI lecture - Clifford Ellgen, Ordinal ResearchInstitute, USA

Our next IPI Talk will be on Saturday, 11^th of Jan. at 16.00 London time. 

Title: Knot Physics: Particle Knots and Entropic Dynamics

Abstract:

Knot Physics is a geometric approach to quantum gravity. Many theories of quantum gravity attempt to make general relativity into a particle theory. By contrast, Knot Physics makes quantum field theory into a geometric theory. To accomplish this, we assume that spacetime is a branched manifold that is embedded in a higher dimensional space. The manifold can be knotted, and those knots are elementary particles. The branches of the spacetime manifold are under-constrained. Subject to constraints, branch behavior maximizes entropy. We show how entropy maximization produces all the forces with their corresponding gauge groups. In addition, there is a natural relationship between quantum and classical behavior that is mediated by entropy maximization.
