   Time and space together make spacetime, Figure \(\PageIndex{1}\), the stage on which physics is played out. Until 1905, physicists were trained to accept two mutually contradictory theories of spacetime. I’ll call these the Aristotelian and Galilean views, although my colleagues from that era would have been offended to be accused of even partial Aristotelianism.

   2. Dez. 2015 · Both Special and General Relativity show us that time “creates” space, that although the two always go together, space needs time for it to exists, whereas time does not need space despite the fact that space always comes with it. Time is the fundamental here and space, the emergent. There was an article in New Scientist back in 2015 that ...

   14. Nov. 2022 · Relativity tells a different story. Now there are two distinct notions of what is meant by “time.”. One notion of time is as a coordinate on space-time. Space-time is a four-dimensional continuum, and if we want to specify locations within it, it’s convenient to attach a number called “the time” to every point within it.

   18. Aug. 2023 · Integrated in Einstein’s general theory of relativity, one of the profound revelations about the space-time continuum is its curvature in the presence of mass and energy. In essence, the more mass or energy an object has, the more it warps the space-time around it. Objects move along the ‘paths’ created by this curvature.

   30. Okt. 2009 · That is, each observer, located at his own space or time, can choose degrees of freedom independently than any other observer located at other points of space or time, as long as those degrees of freedom are transformed by the gauge symmetry . Gauge symmetries are so powerful that they restrict greatly the possible equations compatible with the symmetry, so much so that in some cases the ...
