"Biological Intelligence is a Fleeting Phase in the Evolution of the Universe" (Holiday Weekend Feature)
During an epoch of dramatic climate change 200,000 years ago, Homo sapiens (modern humans) evolved in Africa. Several leading scientists are asking: Is the human species entering a new evolutionary, post-biological inflection point? Paul Davies, a British-born theoretical physicist, cosmologist, astrobiologist and Director of the Beyond Center for Fundamental Concepts in Science and Co-Director of the Cosmology Initiative at Arizona State University, says that any aliens exploring the universe will be AI-empowered machines. Not only are machines better able to endure extended exposure to the conditions of space, but they have the potential to develop intelligence far beyond the capacity of the human brain.

"Detection of Laser Light May Signal Presence of Alien Technological Civilizations" (Today's Most Popular)
"Detection of Laser Light May Signal Presence of Alien Technological Civilizations" (Today's Most Popular)
Concentrated laser light in the universe may singal the presence of a technological civilizations that might be living on distant planets. “Think about humanity 300 hundred years from now,” said Geoffrey Marcy this past August. Marcy is currently Professor of Astronomy at the University of California, Berkeley, famous for discovering 70 out of the first 100 exo planets. “Suppose we set up a colony on another planet … the most likely way we will communicate with (humans on those planets) is with radio signals or light beams.” Marcy believes that there may be other civilizations in the universe that are years ahead of human society and might currently be communicating with radio signals in a network he calls a “galactic Internet.”

"How Did Life Begin on Earth?" --A New Theory Embraces the Cosmic through Geological, Chemical, and Biological Stages
"How Did Life Begin on Earth?" --A New Theory Embraces the Cosmic through Geological, Chemical, and Biological Stages
“When the Earth formed some 4.5 billion years ago, it was a sterile planet inhospitable to living organisms,” said Sankar Chatterjee, Horn Professor of Geosciences and curator of paleontology at the Museum of Texas Tech University. “It was a seething cauldron of erupting volcanoes, raining meteors and hot, noxious gasses. One billion years later, it was a placid, watery planet teeming with microbial life – the ancestors to all living things.” “For may years, the debate on the origins of life centered on the chemical evolution of living cells from organic molecules by natural processes. Chatterjee said life began in four steps of increasing complexity – cosmic, geological, chemical and biological. By studying three sites containing the world’s oldest fossils, he believes he knows how the first single-celled organisms formed in hydrothermal crater basins.
