No, the sunlight is not fading away. The Sun, our nearest star, continues to radiate energy and light just as it has for billions of years. The perception of sunlight being "faded" or less intense can vary due to atmospheric conditions, such as cloud cover, air pollution, or even seasonal changes.
On a daily basis, the intensity of sunlight can vary due to factors like the angle at which sunlight reaches the Earth's surface, atmospheric scattering, and the amount of cloud cover. These variations can make sunlight appear brighter or dimmer throughout the day.
However, in the larger context of the Sun's life cycle, it is still in its main sequence phase, where it steadily converts hydrogen into helium through nuclear fusion, releasing vast amounts of energy in the process. This process continues to provide the Earth with the light and heat that sustains life.
It's important to distinguish between short-term variations in sunlight intensity due to local conditions and the long-term stability of the Sun's energy output. The Sun's luminosity has remained relatively constant over human history, and there is currently no evidence to suggest that it is fading away.
