Is the autumnal equinox vertical egg a raw egg? Yes, raw eggs stand easily.

Cooked eggs are more unbearable than raw eggs. Because the center of gravity of boiled eggs has been determined, if the center of gravity does not fall on the supporting surface of eggs, how can it stand upright? The surface or desktop of an egg is uneven. As long as there are any three supporting points, a supporting surface can be formed. As long as the center of gravity of the egg falls on this supporting surface, the egg can stand up. However, it is difficult to find the center of gravity because the surface of the egg is curved and the supporting surface is relatively small. But one thing will not change: the higher the center of gravity, the more difficult it is to balance; The lower the center of gravity, the easier it is to stand upright. This is why experts on vertical eggs will come to the conclusion that it will be better to shake the raw egg and sink the yolk vertically.

Like the vernal equinox, the sun shines directly at the equator of the earth, and day and night are equal. Since then, the position of direct sunlight has moved south, and the days in the northern hemisphere have gradually shortened, the nights have become longer, and the temperature has dropped, which is of universal significance throughout the country. After the autumnal equinox, the days are getting shorter and shorter in the northern hemisphere, and the nights are getting longer and longer in the southern hemisphere. From the winter solstice, the day becomes longer and longer, but from the vernal equinox, the day is longer than the night, from the summer solstice, the day becomes shorter and shorter, but from the autumnal equinox, the day is shorter than the night.
