Now we usually call that image in the night sky 'space', while it actually isn't. What we see there is an image from the past, which is not internally consistent, because depth in space is also 'depth' in time. Usually we ignore this problem and think, the stars we see are real. Well, that's kind of bad luck, because we cannot see certain problems in cosmology, if we adress relations of celestial bodies, which do not belong to the same time. We cannot adress the correct relations, because actually we don't know, where these cosmic objects are now. Now I meant, that even if this picture is flawed, it is used so often under the name 'space', that I could allow this use and use it myself. That 'space' is now unreal, because it is layered in time and shows events happening long ago. But that's actually what we see in the night sky and call it 'space'. >> Such 'space' cannot have real properties, because it does not exist >> outside of the observers brain. >> >> But something does exist, which has properties and those appear as >> space and time according to known laws. >> >> This something cannot be 'space', but must be real and also >> 'relativistic'. >> >> I took spacetime of GR as real and our observations from a certain >> perspective as not. >> >> Therefore, this real spacetime could serve as an equivalent to >> 'aether' and can have properties. >> >> I have actually written kind of book about this idea several years >> ago.

My guess: there exists something, which appears as space and time from different perspectives. A view from somewhere is then something like a 'cut', which ascribes spatial and temporal relations to something, which is invisible itself. Only such local observations are possible. This is very similar to the observation of the local environment on different sides of the Earth. Everywhere the surface looks more or less flat and the horizon slightly curved, while the vertical is always vertical. Now replace 'vertical' with 'axis of time' and 'horizontal' with 'spacelike'. TH
