ALIEN OBSERVED NOW. “The fact that to such an observer our now is shifted does not necessarily mean it is shifted for us, since an infinity of such observers in random positions and velocities would cancel each other out. Such an apparent shift can only occur at a distance such that our now as observed by the alien is in our past and unchangeable anyway, so what is the relevance of any alien's observation to our present?” https://lnkd.in/gDaxUYAS View in LinkedIn

NO UNIVERSAL NOW. “Since this is true of all distant moving observers with different velocities, it is deduced that there should be no preferred present. I believe this is a philosophical prejudice, and Einstein was notoriously wrong in his philosophical prejudices.” https://lnkd.in/gDaxUYAS View in LinkedIn

THE PROBLEM OF NOW. “But, according to Einstein, an alien, for example, observing us in a distant galaxy will perceive our now to be shifted into our past or future, versus its neighbor alien observing us at a somewhat different velocity.” https://lnkd.in/gDaxUYAS View in LinkedIn

WIPED CLEAN. “Loss of that shielding, during the next geomagnetic polarity reversal, will potentially have devastating consequences for our highly integrated, technology-based infrastructure.” (Header reference to Blade Runner 2049) https://lnkd.in/g3Z5rDbb View in LinkedIn

FROM CHEMISTRY TO BIOLOGY. “There is no fundamental difference between a living organism and lifeless matter. The complex combination of manifestations and properties so characteristic of life must have arisen in the process of the evolution of matter.” (Oparin, A (1938), note “evolution of matter”). https://lnkd.in/dAtB9vYM View in LinkedIn

INTERPRETATION. “H.A. Lorentz preferred the view that there is indeed a state of "real" rest, defined by the aether (now by the cosmic microwave background radiation) though it could not (then) be identified experimentally. In Bell's words: "the facts of physics do not oblige us to accept one philosophy rather than the other".” https://lnkd.in/gDaxUYAS View in LinkedIn

FINAL HURRAH. “It is now necessary to defend the previous assumption that only the present and antipresent can accommodate interactions. An absolute rest frame can be provided by the cosmic background radiation in present theory, using the doppler effect to establish our motion relative to it.” https://lnkd.in/gDaxUYAS View in LinkedIn

LEVEL FIELD. “According to J.S. Bell, Einstein's theory assumes that the laws of physics will look the same to all observers in uniform motion, permitting a very concise and elegant form of the theory.” https://lnkd.in/gDaxUYAS View in LinkedIn
