Paul,

Thank you for this. I have downloaded your diagrams and will consider your points later this evening. Please excuse me if I do not respond fully until tomorrow.

Philip M, Neville J, Interested Parties, Ladies and G... oops! Getting carried away.

Neville, thank you for a concise summing up. (Clarification -- Sat 27/10/07 10:22 PM) Let me build on almost all of it.

 

Part 1 -- Getting a feel for the subject.

If you will grant me the indulgence, the galaxy is, to a first approximation, stationary. We are aboard Stella Surveyor (see attachment StellaSurveyor.jpg), ten ly from Sol on a direct path to Polaris with which our longitudinal axis is aligned. (Well -- we have to be somewhere. This is as good as any other place so long as we are a long way from Earth and its environs and all the orientational presuppositions which this engenders).

Our craft is rotating in the direction indicated -- CCW -- at a rate of 2 rpm -- too slow to notice any rotational effects. You are seated at the Equatorial View - Wide Field Telescope (EVWFT). Imagine what you will see. For those without imagination, what you will see, is a field of stars (please -- no argument on this point!) which is drifting past your field of view from left to right on straight parallel paths and time lapse photography will vindicate this impression. We now bring our vehicle to a stop, change its orientation so as to bring our longitudinal axis into alignment with the direction to Sirius and bring its rotation rate back up to 2 rpm in the same CCW direction. Looking through the EVWFT, we will again see stars drifting past our field of view on straight parallel courses from left to right.

We can repeat this exercise any number of times aligned with Spica, Vega, Proycon, Capella, Rigel or any of hundreds of thousands of other stars and what we see will always be the same -- stars drifting past our field of view from left to right at two passes per minute.Now for the interesting bit. Move to the Polar View - Wide Field Telescope (PVWFT) and again imagine what you will see. If we are aligned with Rigel and rotating again CCW at 2 rpm, we will see a stationary Rigel smack bang in the middle of the field of view but the star field will appear to be rotating CW around Rigel twice every minute. Stars with small angular separation from Rigel will describe small diameter circles while those with larger angular separation will describe larger circles and again time lapse photography will confirm our impression. If we bring our vehicle to a stop and reorient our longitudinal axis so that it points at Capella, and look again through the PVWFT, we will see the same scenario as before but this time with Capella smack bang in the middle. Circular star trails will again be evident.

As before, it won't matter which star is on our longitudinal axis, the view presented will be the same -- circles described by stars having angular separation from the target star which is smack bang in the centre of the frame.

While you have been looking at concentric circles through the PVWFT, your companion on board can observe through the EVWFT and will report left to right passes of the field of stars on parallel courses, each at the rate of two passes per minute and occurring synchronously with the circular passes.

The point of all this is that there is nothing magical or mysterious about star trails -- a virtual infinity of them are possible. If you want to see these concentric circles in time lapse photographs of star fields, then you need do only two things. First, keep the object of interest -- the axis of rotation extended to infinity -- in the centre of your frame of interest and second, arrange for an exposure of sufficient duration to record the rotation.

NB. An approximation has been made above in relation to the parallel paths of stars visible in the EVWFT. In fact, stars vertically either side of the centre of the field of view will be increasingly curved towards the pole of rotation -- upwards and downwards if you prefer but this does not materially alter the explanation.

 

Part 2 -- Rotation about the Ecliptic Poles (and how to record it).

Proposition 1. The Earth rotates on an axis through the geographic poles once per sidereal day.

Proposition 2. The Earth simultaneously revolves around the Sun in 365.25 mean solar days..

If Proposition 1 is true, then there will be apparent rotation of the star field around the extension of the Earth's axis of rotation at a rate of once per sidereal day.

This can be photographically recorded by taking a time lapse photograph with a stationary camera whose z-axis is aligned with the Earth's axis of rotation thus centred on either the North or the South Celestial Pole. An exposure of as little as one hour duration will suffice.

The only contention here is which body is moving -- Earth rotates or Universe rotates.

If Proposition 2 is true, then there will be apparent rotation of the star field around the Earth's axis of revolution around the Sun at a rate of once per 365.25 mean solar days.

Since the Earth's axis of rotation is inclined to the plane of the ecliptic at an angle of 23 1/2 degrees, it will be convenient to place a camera to photograph the expected revolution about the ecliptic pole at a point on the Earth's surface at 23 1/2 degrees north latitude (if we are to centre our photograph on the North Ecliptic Pole, south if otherwise) on an arbitrary meridian, say 0 degrees. This will keep our feet dry.

For this exercise, it would be convenient if the Earth rotated on its polar axis once per year (synchronous rotation) and its polar axis were to be reoriented to align with the ecliptic poles. If this were so, then there would be no axial inclination with respect to the plane of the ecliptic, the North and South Celestial Poles would coincide with the Ecliptic Celestial Poles and we wouldn't be having this discussion because it would all be so frightfully obvious. Sadly this cannot be realised but it can be simulated by using a camera mount which compensates for the Earth's lack of cooperation and this will give the same result. Please make reference to the attachment "EclipticPoles.jpg" -- Rotation around Ecliptic Poles.

The Camera Mount section of the illustration shows how we must mount our camera. The Mounting Bearing must be fixed to the Earth such that the bearing is exactly parallel with the Earth's axis of rotation. This would be horizontal if it were at the Equator and pointing due North, however we are at 23 1/2 degrees North latitude thus the bearing will be mounted at an angle of 23 1/2 degrees to the horizontal, pointing North, and higher at the North end.

For clarity of explanation, we will begin our experiment at midnight on the Northern Summer Solstice. On this night, we must align the camera mount and start the motor drive. First, rotate the shaft until the upper, offset section is in line with the plane of longitude and engage with the stationary motor. Second, rotate the bearing section of the platform until the 'Y' axis of the camera is in line with the plane of longitude and hold it in that position with an extension spring whose other end is fixed to the Earth. Wait for midnight and at that time, switch the motor on and make one exposure of short duration. The motor is geared such that the shaft will rotate CW once per 365.25 Mean Solar Days. This will ensure that at midnight each day, the camera 'Z' axis will be aligned with the North Ecliptic Pole and the 'Y' axis will be aligned with the Sun, having been moved radially by the Earth by an amount of 365.25/360 degrees as compared with its position 24 hours previously. At this time on each and every day for 365 days, make another exposure of short duration. Note that the camera 'Z' axis will only be correctly aligned at midnight. It could be arranged to be correctly aligned at all times by having the motor rotate once per mean solar day but there is no need to needlessly wear out the mechanism so long as the exposures are made at midnight.

At the end of the year, we can remove the camera and process the film. At that time, there will be evident many concentric circular star trails each consisting of 365 dots and centred on the North Celestial Pole. Actually, it wouldn't really be necessary to wait the full year -- the trend will already be evident (and the image will be less 'busy') by the end of a week or two.

Now -- does this demonstrate that the Earth revolves around the Sun? No it doesn't. If the Earth is stationary and the stars revolve CW around the Earth centred on the geographic polar axis once per sidereal day, the picture at the end of the year will be the same.
