Orientation in space and time on a rotating surface

We have found the four co-ordinates, and with them the basis of an individual space-time continuum, and are now able to further investigate this specific event. For that purpose I shall try to visualize how space might look from such a specific place and time on earth. First we take a look at the relative movement of earth and sun inside the celestial sphere from some point in space.
The tilt of the earth's axis with respect to her orbit around the sun causes local differences between day and night, the seasons. Precisely because of this tilt it is hard to imagine the movement of objects in space such as the sun. Therefore I'll begin with the representation of the least complicated situation; the anti-clockwise movement of the earth in her daily rotation around her axis. The pictures in series 1 represent the situation on the northern side of the globe, where the zenith/nadir-axis coincides with the earth's axis, whereas the horizon (to be envisaged as a plane stretching out to the stars, as we have seen in ZZZ#9) coincides with the earth's and the celestial equator. At the North Pole, at the end of summer, the sun still remains day and night just above the horizon.
Clicking the picture will display twelve different situations and you can simulate the rotation. With respect to the precision I must ask you not to expect too much. The inclined ellipses were placed from view, which has consequences for the precision of the intersections.
 

Local horizon and directions from a 52° angle

The following series of pictures shows a situation at the 0° meridian somewhere near 52° North Latitude. We would be at Greenwich. The little figure continues to be turned toward us. Now he has the North at his left side, the South at the right, West is behind him and he looks at us in an Eastern direction. We want to know where the Ascendant is to be found (the horizon intersects with the sun's apparent path, the ecliptic, at two points: the eastern is called Ascendant, the western point of intersection is the Descendant).
 

From the centre: setting up a more distinct map

Up until now we have looked at the motion from a distance. The data of the individual system of co-ordinates are available in Ascendant tables and ephemerides or we can use computer programs to calculate them. Right now I want to dwell a little longer on the question of how we can organize the information in a readable and serviceable form, for that is lacking in the above pictures. To make a well-defined map of an event we proceed as follows:

1. The circle of the ecliptic (the path which the sun describes against the celestial sphere as seen from the earth) contains the information about its actual origin or point zero and about the sun;
2. The co-ordinates of the event at the earth's surface, namely the South, the Ascendant and the zenith, can be projected on the ecliptic. In the same way, the other points of the compass, the Descendant and the Nadir, as they are derived from those, can also be added. In this way we transpose our standpoint from somewhere outside the celestial sphere to the specific place and time of that one event in which we are interested;
3. The joint orbits of the Moon and of the planets form the Zodiac (a band against the celestial sphere on both sides of the ecliptic). The actual places of the Moon and the planets can be projected on the ecliptic. This adds just as many new co-ordinates and the most exact time;
4. The star signs or signs of the zodiac (to be distinguished from the constellations which are spread over the whole celestial globe) can, starting at the origin at point zero, be added to the data on the circle;
5. The information can be amplified by putting the twelve phases of the human process in the circle, starting from the Ascendant or from any other point to be studied;
6. The connections between data on the circle can be drawn on the map.

The charted movement of the Ascendant

For comparison with the visualization in the second series above, I'll show a series of twelve maps which represent the same steps of the daily movement. You'll see that the relations between the various parts are very clear in this rendition.
 

Knowledge of space and time

It may seem as if I have strayed from my goal. I must admit, quietly studying the daily movement, which we can observe with the naked eye but of which the structure is not easily visualized, I enjoyed the interesting trail. I do believe, however, that I have construed a strong base for handling Einstein's idea. For me, in my search for insight into life, the importance of knowledge of space and time is a certain fact.

At this point I can close the subject. We now have the disposal of a space-time map which shows characteristics of a certain point in space and time; as the map of an area refers to characteristics of an area and the hands of a clock refer to points in time in a continuous progress of time so the co-ordinates of our map refer to the characteristics of specific events. It is a map of the infrastructure of an event, of the interaction between an individual system with its surrounding systems, of a process in which the basic faculties of life, namely action, recollection, knowledge and emotion, are being co-ordinated in an individual manner by alternately initiating, applying and adapting them. The old astrologers would be proud if they had known how appropriate their method still is in throwing light on such a complicated matter as life, even in the present so much larger world.
