Is there a common chemical model for life in the universe?
A review of organic chemistry suggests that life, a chemical system capable of Darwinian evolution, may exist in a wide range of environments. These include non-aqueous solvent systems at low temperatures, or even supercritical dihydrogen-helium mixtures. The only absolute requirements may be a thermodynamic disequilibrium and temperatures consistent with chemical bonding. A solvent system, ava...
متن کاملHow much sweetness is there in the universe?
We continue investigations of forcing notions with strong ccc properties introducing new methods of building sweet forcing notions. We also show that quotients of topologically sweet forcing notions over Cohen reals are topologically sweet while the quotients over random reals do not have to be such. One of the main ingredients of the construction of the model for all projective sets of reals h...
متن کاملKnowing Afghanistan: Can there be an end to the saga?
War on terrorism, as the motto which formed the cornerstone of global policies of former neo-conservative administration of the United States, is increasingly becoming ineffective in Afghanistan with the dreaded consequence of spilling over into Pakistan. This inevitable consequence of War on Terrorism in Afghanistan has brought the West face to face with the ‘nest of terrorism’ that CIA...
متن کاملIs There an Alternative to the Block Universe View?
This paper pursues two aims. First, to show that the block universe view, regarding the universe as a timelessly existing four-dimensional world, is the only one that is consistent with special relativity. Second, to argue that special relativity alone can resolve the debate on whether the world is three-dimensional or four-dimensional. The argument advanced in the paper is that if the world we...
متن کاملWhere There is Life There is Mind: In Support of a Strong Life-Mind Continuity Thesis
This paper considers questions about continuity and discontinuity between life and mind. It begins by examining such questions from the perspective of the free energy principle (FEP). The FEP is becoming increasingly influential in neuroscience and cognitive science. It says that organisms act to maintain themselves in their expected biological and cognitive states, and that they can do so only...
