Project SETI: Machine Recognition of Squiggles in SETI Signal Data

The singular question, are we alone?, has boggled scientists for centuries. The SETI Institute operates the Allen Telescope Array (ATA) to observe star systems for radio signals which may provide evidence of extraterrestrial intelligence. Signal events that maintain an intensity above an empirically-set threshold across all frequencies are converted into spectrogram images through a sliding-win...

Nepal’s West Seti Project Imbroglio: The Supreme Court Speaks

The history of Indo-Nepal water resource cooperation is a litany of dashed hopes, shelved projects, treaties lacking implementation, and mutual recrimination. The small-neighbor versus big-brother syndrome that pervades relations in every sphere invariably arouses suspicion of unequal benefits. In this context the West Seti Hydroelectric Project in far western Nepal, the biggest energy generati...

Extragalactic Seti and the Uws/atnf/serendip Project

SETI is generally confined to Galactic targets, especially nearby solar-type stars, because the enormous distance to other galaxies increases the power required for a transmitter by ~8 orders of magnitude compared to nearby stars. Here I show that the required power for intergalactic SETI is physically attainable, and furthermore other factors increase the probability of detection, so that it i...

SETI, Evolution and Human History Merged into a Mathematical Model

In this paper we propose a new mathematical model capable of merging Darwinian Evolution, Human History and SETI into a single mathematical scheme: (1) Darwinian Evolution over the last 3.5 billion years is defined as one particular realization of a certain stochastic process called Geometric Brownian Motion (GBM). This GBM yields the fluctuations in time of the number of species living on Eart...
