When I was a child, I saw a fast-moving circular aperture in the sky at night, like a big moon, moving very fast, and definitely not a searchlight without light.

I've seen different colored apertures, and I remember trying to catch him, but he avoided it, as if he had opened his eyes, as if playing with me on purpose. Apertures will regularly gather on the big aperture of the sky. When you gather, you can see that the big aperture changes from thin to thick, and then it will fly down one by one, with different colors and sizes. This size is not caused by distance. Water, like light, can float on the surface without ripples (because there is a river when I see it). Like the light you shine with a flashlight, they are still 90-degree apertures. It feels like someone in the sky is teasing you with a colorful giant flashlight, but it can be clearly seen that it can't be artificial light, because that color is as simple as only one color in a rainbow. I mean, we all know that the light we see every day is composed of seven colors, and the color of the aperture seems to be translucent as if only one of them exists independently. I saw it around nine o'clock in the morning. There can't be such a powerful laser light around the farmland. Besides, it shouldn't be the artificial high-tech I saw in the 1990 s 20 years ago. And it lasted about half an hour. At the end of walking, the moving speed is more than 30 times that of modern technology (relative to the flying speed of rockets), so there is no need to have such a long boosting force at the beginning of the movement like rockets. It is so light, as silent and fast as when you slowly cross the sky with a flashlight.
