ADMONITION. “Before the phenomenon of nature it is necessary to observe, to study and to be astonished by nothing.” (Leibniz). View in LinkedIn

UNITS OF TIME. “Indeed, with a finite speed of light, everything we see is in the past. As discussed above, the whole idea of detecting the antipresent requires a preferred now. In the STH there is always a single present moment throughout both the universe and the antiuniverse.” (STH = Symmetrical Time Hypothesis). https://lnkd.in/gDaxUYAS View in LinkedIn

SPEED LIMIT. “Relativistic interactions are limited by the speed of light. Since everything happens at a finite distance from everything else, relativity can only deal with the past, even if only infinitesimally in the past.” https://lnkd.in/gDaxUYAS View in LinkedIn

FUTURO OSCURO. “Somehow the present must allow the future to be consistent with relativity, but we cannot measure anything in the future.” https://lnkd.in/gDaxUYAS View in LinkedIn

LOCKED PRESENT. “Quantum interactions are instantaneous, they can only occur in the present, where the volume of the light cones in Minkowski spacetime is zero.” 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

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

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
