Organized Complexity: is Big History a Big Computation?
Jean-Paul Delahaye, Clement Vidal
The concept of "logical depth" introduced by Charles H. Bennett (1988) seems to capture, at least partially, the notion of organized complexity, so central in big history. More pre…
Pulsar Positioning System: A quest for evidence of extraterrestrial engineering
Clement Vidal
Pulsars have at least two impressive applications. First, they can be used as highly accurate clocks, comparable in stability to atomic clocks; secondly, a small subset of pulsars,…
Black Holes: Attractors for Intelligence?
Clement Vidal
The Search for Extra-Terrestrial Intelligence (SETI) has so far been unsuccessful and needs additional methods. We introduce a two-dimensional metric for civilization development,…
The Future of Scientific Simulations: from Artificial Life to Artificial Cosmogenesis
Clement Vidal
This philosophical paper explores the relation between modern scientific simulations and the future of the universe. We argue that a simulation of an entire universe will result fr…
Computational and Biological Analogies for Understanding Fine-Tuned Parameters in Physics
Clement Vidal
In this philosophical paper, we explore computational and biological analogies to address the fine-tuning problem in cosmology. We first clarify what it means for physical constant…
Prime Focus Spectrograph (PFS) for the Subaru Telescope: Overview, recent progress, and future perspectives
Naoyuki Tamura, Naruhisa Takato, Atsushi Shimono +97
PFS (Prime Focus Spectrograph), a next generation facility instrument on the 8.2-meter Subaru Telescope, is a very wide-field, massively multiplexed, optical and near-infrared spec…
