Human Version 2.0
Meet the scientific prophets who claim we are on the verge of creating a new type of human – a human v.2.0. It’s predicted that by 2029 computer intelligence will equal the power of the human brain, a point of convergence referred to as the Singularity. Some believe this will revolutionize humanity – we will be able to download our minds to computers extending our lives indefinitely. Others fear this will lead to oblivion by giving rise to destructive ultra intelligent machines.
Stellar-mass black holes form from the most massive stars when their lives end in supernova explosions. The Milky Way galaxy contains some100 billion stars. Roughly one out of every thousand stars that form is massive enough to become a black hole. Therefore, our galaxy must harbor some 100 million stellar-mass black holes. Most of these are invisible to us, and only about a dozen have been identified. The nearest one is some 1,600 lightyears from Earth. In the region of the Universe visible from Earth, there are perhaps 100 billion galaxies. Each one has about 100 million stellar-mass black holes. And somewhere out there, a new stellar-mass black hole is born in a supernova every second.
Supermassive black holes are a million to a billion times more massive than our Sun and are found in the centers of galaxies. Most galaxies, and maybe all of them, harbor such a black hole. So in our region of the Universe, there are some 100 billion supermassive black holes. The nearest one resides in the center of our Milky Way galaxy, 28 thousand lightyears away. The most distant we know of lives in a quasar galaxy billions of lightyears away.
From All Science, All the Time
Professor Steven Benner will tell geochemists gathering today (Thursday 29 Aug) at the annual Goldschmidt conference that an oxidized mineral form of the element molybdenum, which may have been crucial to the origin of life, could only have been available on the surface of Mars and not on Earth. "In addition", said Professor Benner "recent studies show that these conditions, suitable for the origin of life, may still exist on Mars. Read More
Where does Consciousness Exist?
Where sits the Consciousness? What is Consciousness? Recently it was found out that both hemispheres can be missing yet the children (though severely impaired) are still Conscious! Laughing without a Brain: "Got a Towel?" Case studies suggest that some forms of consciousness may not require an intact cerebrum. This video may answer that question.
