(In »Intensities and phenomena in a relationalist universe«)

With the advent of relationalist physics – for example in the form of loop quantum gravity and shape dynamics – we gain access to a new concept that is a logical consequence of all local times moving in the same direction, but this does not make it possible for us to compare them via divinely external meta-timekeeping. This is global time, which is best described as the aggregate internal duration for the Universe as a whole, without any external observer. Global time indeed comprises everything and everybody in the Universe, but without it ever being able to be localised, and thereby without it ever being measurable, since any kind of measuring of something that cannot be located requires some kind of mysteriously arisen observer position outside the Universe (one cannot be both inside and outside the Universe at once, not without being some kind of Platonist, dualist magician). The specific conditions that influence global time do of course by definition only exist globally when our whole entangled Universe without exception is included in the temporal equation, and never locally in any distinct region of, or even less so, outside the Universe. Global time thereby differs radically from classical metatime as a concept. It is both a universal and at the same time monist duration; a meme, quite plausible to physics, but which seems to pass by the otherwise so revolutionarily inclined Einstein, without leaving any deep impression.
