New Solution To The Fermi Paradox Suggests The Great Filter Is Nearly Upon Us
Posted by Dan Breeden in categories: alien life, existential risks
How optimistic.
First, a little background. With 200 billion trillion (ish) stars in the universe and 13.7 billion years that have elapsed since it all began, you might be wondering where all the alien civilizations are at. This is the basic question behind the Fermi paradox, the tension between our suspicions of the potential for life in the universe (given planets found in habitable zones, etc) and the fact that we have only found one planet with an intelligent (ish) species inhabiting it.
One solution, or at least a way of thinking about the problem, is known as the Great Filter. Proposed by Robin Hanson of the Future of Humanity Institute at Oxford University, the argument goes that given the lack of observed technologically advanced alien civilizations, there must be a great barrier to the development of life or civilization that prevents them from getting to a stage where they are making big, detectable impacts on their environment that we can witness from Earth.

AI Could Explain Why We’re Not Meeting Any Aliens, Wild Study Proposes
Posted by Zola Balazs Bekasi in categories: alien life, existential risks, finance, media & arts, robotics/AI, transportation
Artificial Intelligence is making its presence felt in thousands of different ways. It helps scientists make sense of vast troves of data; it helps detect financial fraud; it drives our cars; it feeds us music suggestions; its chatbots drive us crazy. And it’s only getting started.
Are we capable of understanding how quickly AI will continue to develop? And if the answer is no, does that constitute the Great Filter?
The Fermi Paradox is the discrepancy between the apparent high likelihood of advanced civilizations existing and the total lack of evidence that they do exist. Many solutions have been proposed for why the discrepancy exists. One of the ideas is the ‘Great Filter.’

South Korea launches second military spy satellite
Posted by Saúl Morales Rodriguéz in categories: existential risks, military, satellites
The Koreas each launched their first spy satellites last year — North Korea in November and South Korea in December — amid heightened animosities. They said their satellites would boost their abilities to monitor each other and enhance their own missile attack capabilities.
South Korea’s second spy satellite was launched from the Kennedy Space Center in Florida on Sunday evening local time, which was Monday morning in Seoul.
South Korea’s Defense Ministry said it confirmed the satellite entered orbit and communicated with an overseas ground station after separation from a rocket.
