The United Nations briefly considered the issue of extra-terrestrial intelligence at the 32nd session of the General Assembly in 1977. As a result, the Office of Outer Space Affairs was tasked to prepare a document on issues related to 'messages to extra-terrestrial civilizations', but this area has not been followed through in more recent times. This discussion paper describes the United Natio...

We utilize anthropic reasoning to demonstrate that we are typical observers of our reference class under a self-sampling assumption by investigating the definition of what a civilization is. With reference to the conflict between such reasoning and the observational lack of extra-terrestrial intelligent life, we conclude that a part of our theoretical understanding of the Universe will be at fa...

This research aims at building a preference-based player model of Civilization IV players. Our model incorporates attributes which are defined for AI players. We use a sequential minimal optimization (SMO) classifier to build the player model based on a training set with observations of a large number of games between six AI players. The model was validated on a test set of games between the sa...

Advanced civilizations must radiate heat while utilizing planetary energy sources. This waste heat can be a thermodynamic marker of Earth-like civilization. Here we model such planetary radiation and propose a strategy for detecting an alien unintentional thermodynamic electromagnetic biomarker. We show that astronomically observable infrared civilization biomarkers can be detected within an in...

IN HIS CLASSIC WORK Science and Civilization in China, Joseph Needham explored the historical reasons why China, for all its long civilization, never developed science as we understand it in the modern West, namely a quantitative, technologically driven science of the outer, physical world. In this paper I shall first outline some of the reasons why Western civilization has never developed a sc...

In the present study, the dignity of science and technology in modern civilizations is evaluated as the vital status of the ontological and of "Being" and "Not-Being" type, while emphasizing that the problem description in religious models of new civilization cannot be reduced to the acquisition of modern and strategic science and technologies; Accordingly, this article, while reviewing and cri...
