Proved by reality, that's why they propose to reduce or even undo human emissions.
Metabolic byproducts, chemical gradients, and behavioral patterns automatically transmit information. Physical proximity creates mandatory information channels.
Environmental sharing makes communication inevitable, not optional.

This paper proposes a new approach to understanding gravity by connecting it to concepts from statistical mechanics and information theory. Here's a breakdown of the key ideas:
The author, Ginestra Bianconi, develops a theory where:
1. Spacetime geometry is treated as a quantum object, specifically as an "effective density matrix" 2. Matter fields are described topologically using what's called a "Dirac-Kähler formalism" 3. The interaction between matter and geometry is captured through a mathematical concept called "quantum relative entropy"
The theory introduces a "G-field" that serves as a link between matter and geometry. When this mathematical framework is developed, it produces modified Einstein equations that:
- Reduce to standard Einstein equations in certain conditions - Generate a small positive cosmological constant (potentially explaining dark energy) - Result in second-order equations that might avoid certain mathematical problems
The potential impacts of this work include:
- Providing new insights into quantum gravity (combining quantum mechanics and general relativity) - Offering a possible explanation for dark matter through the properties of the G-field - Creating a mathematical framework that connects geometry, information theory, and quantum mechanics
The paper builds on the author's previous work but extends it to a fully continuous, Lorentz-invariant theory that can describe real physics in four-dimensional spacetime.
Do we need Frank Herbert’s spice to progress?
Instead the wealth accumulates in places unreachable for 99% of us.

Won't raising support cost at some point suggest it's cheaper having two swappable live systems than the alternative?
