Most people take it for granted that we have yet to make contact with an extraterrestrial civilization. Trouble is, the numbers don’t add up. Our Galaxy is so old that every corner of it should have been visited many, many times over by now. No theory to date has satisfactorily explained away this Great Silence, so it’s time to think outside the box. Here are eleven of the weirdest solutions to the Fermi Paradox.
For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as a definite location and instead existing everywhere and nowhere at once. Only when a particle is measured does it suddenly…
Let me introduce The Machine- HP’s latest invention that could revolutionize the computing world. According to HP, The Machine is not a server, workstation, PC, device or phone but an amalgamation of all these things.
Forget close encounters of a third kind. Imagine galactic encounters with millions of planets in the Milky Way galaxy, each of them overflowing with complex life forms. A new study says it’s a possibility.
Consciousness is one of the most fascinating and elusive phenomena we humans face. Every single one of us experiences it but it remains surprisingly poorly understood. That said, psychology, neuroscience…
The belief in human exceptionalism, so strongly rooted in the Judeo-Christian view of the world, flies in the face of all evidence for the structural and behavioral continuity between animals and people.
Newly published research signifies the reinterpretation of cold dark matter, opening up the possibility that it could be regarded as a very cold quantum fluid governing the formation of the structure of the Universe.

Google hired the noted inventor and futurist to build artificial intelligence that can think like a human. His vision is a computer with a structure modeled on the human brain, giving it a capacity for abstract thought.
Astronomers have discovered two new super-Earths orbiting an ancient 11.5 billion year-old star a "mere" 13 light-years from here. One planet is in the habitable zone, prompting a researcher to wonder what kind of life could have evolved over such a long period.
This article brings together three findings and ideas relevant for the understanding of human consciousness: (I) Crick's and Koch's theory that the claustrum is a “conductor of consciousness” center crucial for subjective conscious experience. (II) Subjective reports of the consciousness-altering effects the plant Salvia divinorum, whose primary active ingredient is salvinorin A, a -opioid receptor agonist. (III) The high density of -opioid receptors in the claustrum. Fact III suggests that the consciousness-altering effects of salvinorin A are due to a κ-opioid receptor mediated inhibition of primarily the claustrum and, additionally, the deep layers of the cortex, mainly in prefrontal areas. Consistent with Crick & Koch’s theory that the claustrum plays a key role in consciousness, our analysis of the subjective effects of Salvia divinorum finds that salvia disrupts certain facets of consciousness much more than the largely-serotonergic hallucinogen LSD. Based on this data and on the relevant literature, we suggest that the claustrum does indeed serve as a conductor for certain aspects of higher-order integration of brain activity, while integration of auditory and visual signals mostly relies on coordination by other areas including parietal cortex and the pulvinar.
