This effect occurs due to the perspective and the way light is refracted and reflected by the atmosphere, creating the appearance of a tunnel-like pathway towards the sun. It is a visually striking and often surreal sight that can be observed in certain atmospheric conditions, especially during sunrise or sunset. **

This can vary depending on the context and purpose of the tunnel, but in general, a tunnel is considered to be a significant and substantial passageway. **
