Why do stars twinkle?
Stars are lights in the Firmament projected by a stationary Celestial Sphere. The Heads Over Thousands drag the lights in the Firmament from east to west.
According to scientists, stars are just flickering lights, similar to flickering light bulbs, but if we zoom in on a twinkling star, we see a completely different picture.
The picture above shows close up images of a twinkling star in the firmament. The images tell us three things –
First - stars are not just flickering as light bulbs do. The flickering of a star is a rapid changing of colors. In fact, we can see all colors of the rainbow in a twinkling star.
Second - we can see multiple colors at time in one twinkling star. Moreover, there are sharp transitions between different colors within one twinkling star. The atmosphere would not be capable of creating the sharp transitions between the colors.
Third - the colors occur in parallel layers. For example, there is one layer of purple, one layer of yellow, and one layer of green. All three layers make up one single star. This is not an individual case, but the general principle behind the twinkling – a rapid changing of colors over multiple parallel layers.
This shows that the firmament has parallel and sharp ripples which cause the observed refraction. As the “lights” sweep over the solid firmament, at the speed of approximately 1000 miles per hour, they are refracted by those “ripples”, which creates a rapid changing of colors over several layers which is generally known as the twinkling of stars.
