1. What is the celestial meaning of the Autumnal Equinox (AE)?

When the planes of Celestial Equator and Ecliptic intersect (or meet) along a line, both ends of the line (with Earth as the observation point at the center) each point to a node each on the Ecliptic (where the readings of Ecliptic & Equator coincide). One is the Ascending node (in Vernal Equinox) and the other(while descending) is the Autumnal Equinox (AE).

2. What is the astronomical meaning of the Autumnal Equinox?

Sun appearing on either node, signifies that the day & night are equal (=12 hours). Autumn Equinox (September 23) is the Sun's address as seen from Earth.

3. What is the cultural meaning of the Autumnal Equinox?

In different geographical areas of the globe its meaning varies being purely Anthropocentric.

4. Why don't we still celebrate the Autumnal equinox?

And who is preventing you from celebrating?

In India (where Lunar Calender is followed) AE signals the start of the festive season (9-day 'Dasara' followed by the festival of lights on New Moon - 'Deepavali') when the month's Full moon occupies the position of Sun at Vernal Equinox.

5. How does it affect people?

The climate turns pleasant, neither too hot (at the end of Summer) nor too cold (prior to Winter) and that is how people are affected.

6. Why is the moon seen in the day time?

This has nothing to do with AE. Moon does appear on day time half the days (to clear your confusion watch Moon for a couple of months every day).

7. When will that stop?

{stop what?} Whoever asks this, it is a ridiculous & stupid question .

8. How does the natural world use the Autumnal Equinox?

Yet another R & S question. Natural World is what is outside the human experience.

If that is so, you must know that the word "use" is only in connection with humans. Outside of it there is no use for anything to anything.

9. What happens after the Autumnal Equinox occurs?

After AE, countdown starts like 2 days after AE, month after AE and so on {Isn't the question stupid again? If your Professor is an idiot, it is no reason you should dump idiotic questions here; only an irresponsible person does that.}

What is the Autumnal Equinox?

You are aware that the axis of rotation of the Earth is tipped 23 degrees off vertical to the plane that the Earth orbits in around the Sun, yes? The equinox is that point in the orbit when the north pole and south pole are equidistant from the center of the Sun. This happens twice, on opposite sides of the Sun as we orbit the Sun, spring and fall These points mark the change of season in spring and fall. In essence, if you draw a triangle between the north pole, the south pole and the center of the sun, the sides connecting the poles to the sun are equal length. The opposite condition is a solstice, when either the north pole or the south pole is tipped toward the sun. If you mark the position of the sun at high noon every day, the shape formed by the points is called the analemma. The end points of the figure 8 shape is the solstices when the sun stops moving north or stops moving south and starts going the other way. Here is a link where you can see what it looks like:

The midpoints of this curve are the equinox points.
