How Social Networks Shape Wealth Sharing and Societal Divides

This study investigates how social network structures affect collective decisions on wealth redistribution and polarization. Using a computational model and an online experiment, researchers explored the impact of wealth-based assortativity and visibility on voting, satisfaction, and fairness. Results indicate that most networks obscure inequality. Maximum assortativity (segregation by wealth) leads to the lowest redistribution and polarization. Conversely, high visibility of the rich results in the highest redistribution and polarization. Notably, segregation keeps the poor satisfied despite remaining poor, while observing the rich makes them dissatisfied even when better off. The findings suggest increasing visibility of excessive wealth can boost redistribution, but risks increased polarization.

A New Concept for 'Now' That Works with Einstein's Relativity

This paper introduces a new way to define 'co-presentness' (what we experience as the present moment) that respects the principles of relativity theory. The authors distinguish between 'simultaneity' (sharing the same time coordinate, which can vary with the observer) and 'co-presentness' (a fundamental, observer-independent reality). They propose that this ontological 'co-presentness' can be anchored using formal indeterminism, suggesting an extended, dynamic present. This concept is developed first in branching time and then in branching spacetime, where the extent of the dynamic present is determined by modal correlations.
