There are few parallels in human endeavor than the very deep and profound argumentative disagreement between Neils Bohr and Albert Einstein on the very nature of Quantum Mechanics. While Bohr was in the Copenhagen Interpretation gang, Einstein was looking for the hidden variables. Einstein wrote a paper with Podolsky and Rosen enunciating the EPR paradox. It was a thought experiment. This is how it is described in wikipedia: The EPR paradox draws on a phenomenon predicted by quantum mechanics, known as quantum entanglement, to show that measurements performed on spatially separated parts of a quantum system can apparently have an instantaneous influence on one another. This effect is now known as "nonlocal behavior" (or colloquially as "quantum weirdness" or "spooky action at a distance"). Read more

I haven't been on one recently, but I am assuming that a space flight is a tough experience! Heck, the microbes - those with small robes.. naah... the small guys who only show up under a microscope - have it really tough out there!! So tough they become tougher.... and meaner!! They kill stuff faster and become worse in small quantities! Scientists found Salmonella did kill more mice than their earth resident counterpart for the duration of the journey! So, caveat - if you do go up to space - don't sit next to a salmonella. He may not be the best of friends... 😉 Read more

A new study says that multiple universes exist, as has been postulated by the "Many Worlds theory" of Quantum Mechanics. So, every time a physical possibility is explored - the Universe "splits" - thus creating many alternative outcomes. As if once a move is made on a chess board - then all the possible games are automatically played in the multiple-Universe (multi-verses??) by the same players! Here are the details: Parallel universes really do exist, according to a mathematical discovery by Oxford scientists described by one expert as "one of the most important developments in the history of science".The parallel universe theory, first proposed in 1950 by the US physicist Hugh Everett, helps explain mysteries of quantum mechanics that have baffled scientists for decades, it is claimed.In Everett's "many worlds" universe, every time a new physical possibility is explored, the universe splits. Given a number of possible alternative outcomes, each one is played out - in its own universe.A motorist who has a near miss, for instance, might feel relieved at his lucky escape. But in a parallel universe, another version of the same driver will have been killed. Yet another universe will see the motorist recover after treatment in hospital. The number of alternative scenarios is endless. Read more
