I pose a challenge for you to demonstrate what it is you are claiming with the noon point having duration. Again, don’t worry about scale. Just show a point having a noon position
I'm novice in astronomy. It's not about the challenge but it's all about positive discussion and IMPOV. I may be wrong unless someone agrees.
Figure on the Top Right:) - NOON is an INSTANT when the stationary earth (zero orbital speed) rotates around its axis. "When there is an instant noon, there is an instant midnight as well"
Figure on the Left:)Disc #1: It rotates about its own center which is the center of the sun. The rotation speed of this disc at R=R1=R2... is equivalent to the orbital speed of the outer surface of the earth at the equator (noons on inner circle). Disc#2 rests on Disc#1 as shown.
Disc #2 represents earth with radius r. It also rotates about its axis. The surface of the earth at the equator moves at a speed of 460 meters per second - approx
Figure on bottom Right:)There are two types of motion of the earth
1. Earth's rotation w.r.t its axis (nearly 460 m/s) -
2. Earth's rotation w.r.t sun (nearly 30,000 m/s) -
Both r and R1 are in a straight line at any noon. Since 30,000 m/s is way greater 460 m/s, therefore, an earth orbits around the sun faster than its spin around its axis. Thus line r of earth transfers to another R2 but =R1 on the inner circle but without axial spin (Earth doesn't have a chance to spin completely at this particular moment due to the greater orbital speed) before it spun to an afternoon when the the earth moves forward in its orbit. Now r is in a straight line with R2 not R1. Hence,
Noon is a "
DURATION" between B and A when an earth doesn't have a chance to spin around its axis while simply moves/ drags fast forwards in its orbit.
---:)) Even if a noon is an instant, midnight should also be an instant not multiples midnights for single/instant noon - Isn't midnight a "DURATION" due to its longer path for instant noon according to you in the previous discussion.
