These Physicists Claim They Can Send Messages To The Past

When you try to combine quantum physics with Einstein’s theories, you quickly run into some pretty serious problems. The biggest is that causality – the order in which events occur – becomes uncertain as the rest of quantum physics. A group of physicists have leveraged that uncertainty, and are now claiming that they can send messages to the past using quantum mechanics. It’s not as crazy as it sounds. Let’s take a look.

Philosophy Talks 26: Emergence in Process — Prof. Mark H. Bickhard
Date of the talk: 13th November 2024
Abstract:
Emergence can (potentially) integrate across otherwise dual metaphysics of basic substances or atoms on one hand and higher ‘level’ phenomena, including mental phenomena, on the other. But there are strong arguments against the possibility of emergence, such as from Jaegwon Kim. I will argue that such arguments against emergence assume a metaphysics of ‘atoms’ (particles); that that metaphysics is false; that an alternative is a metaphysics of process; and that process metaphysics makes the possibility of emergence coherent and ubiquitous.
Panel on Representational Paradigms for Cognitive AI
There is a wide gap between current machine learning representations and the way in which our minds represent reality. Our mental representations are dynamic, coherent, unified (in the sense that we establish relationships between all our domains of knowledge, in the context of a global universe), and they are updated on the fly. In this panel, we bring some important thinkers and practitioners of cognitive science, robotics, AI and philosophy together to discuss representations for future generations of AI systems.
This is the first in a series of events on Cognitive Artificial Intelligence. The goal of Cognitive AI is to build and understand systems that can make sense of their environment, combine knowledge and perception, learn to act on domains they have not encountered before, make autonomous decisions and explain them, interact deeply with people and human society.
We are proud to welcome our panelists:
Mark Bickhard: Cognition and Truth Value.
Stephen grossberg: how each brain makes a mind: from brain resonances to conscious experiences.
Yulia Sandamirskaya: Memory, intentionality, and autonomy enabled by neuronal attractor dynamics.
The Learnable Universe
Treating AI as a philosophical project by Joscha Bach.
Why do we find ourselves in a universe that has learnable properties? How is it possible for a symbol to mean something? What is the relationship between observation, perception and knowledge? What is agency? What constitutes a self model?
When we approach Artificial Intelligence as a philosophical project, we gain a fascinating and useful perspective on age-old questions of philosophy.
This short presentation will touch on some of these questions and aims to open up a broader space for discussion.
Our speaker, Joscha Bach, PhD, is a cognitive scientist and AI researcher specializing in computational models of cognition and neuro-symbolic AI.
He has taught and worked in AI research at Humboldt University of Berlin, the Institute for Cognitive Science in Osnabrück, the MIT Media Lab, the Harvard Program for Evolutionary Dynamics.
Hume, Rovelli, and why the quantum world contains no objects
Quantum Mechanics is arguably one of the most successful theories in the history of science, for its predictions are confirmed by countless experiments, making it a cornerstone of contemporary physics. However, a century after its inception, the theory still challenges our classical worldview, offering a counterintuitive description of nature at microscopic scales. Contrary to classical mechanics, where objects are individually distinguishable and possess well-defined attributes at all times, QM speaks about indistinguishable systems with indeterminate properties, superposed states, and non-local interactions. Unsurprisingly, then, questions concerning its ontology, i.e., what fundamentally exists, are still vividly discussed to this day.
Despite its empirical success, however, physicists and philosophers alike enquire whether QM should be considered a true description of the natural world, because this theory is affected by conceptual conundrums and formal difficulties (e.g., the measurement problem). To address such issues, new quantum interpretations emerged from the 1950s. Among the many existing alternatives, here we consider a widely discussed framework that turns thirty this year, Carlo Rovelli’s Relational Quantum Mechanics (RQM).
RQM is motivated by Rovelli’s work in loop quantum gravity, where spacetime is not a substance existing per se, but rather it emerges from a dynamic network of relations, providing a relational perspective of it.
The universal theory of structure: a fundamental ontology for ontic structural realism
Universal nature of structure.
Ontic Structural Realism (OSR) holds that structure is ontologically fundamental, yet it lacks a precise metaphysical account of structure. Returning to the insight that originally motivated structural realism, I develop a new basis for OSR grounded in the metaphysical foundations of mathematics. This approach draws on the principles of ante rem structuralism and their formal axiomatizations to define Structure Theory (ST), the view that structures exist sui generis and constitute the subject matter of mathematics. ST compels OSR to confront its “collapse problem” of distinguishing physical from mathematical structure. I argue for embracing the collapse by adopting the Mathematical Universe Hypothesis (MUH), which identifies our physical universe as an ante rem structure.
