In Newtonian physics, space and time are considered as separate entities and whether or not events are simultaneous is a matter that is regarded as obvious to any competent observer. In Einstein’s concept of the physical universe, based on a system of geometry devised by Hermann Minkowski (1864—1909), space and time are regarded as entwined, so that two observers in relative motion could disagree regarding the simultaneity of distant events. In Minkowski’s geometry, an event is identified by a world point in a fourdimensional continuum." Are they any 'competent observers' in this newsgroups? -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
