The concept of "distance between Earth and the sky" can be a bit ambiguous, as it depends on how you define "sky." The sky is essentially the space above us, extending out into the vastness of the universe. However, if we consider the distance between Earth and the visible edge of the observable universe, it is currently estimated to be about 46.5 billion light-years.
It is important to note that the universe is continuously expanding, and the notion of distance becomes more complex on cosmological scales. The expansion of the universe means that the distance between objects can increase over time.
If you are referring to the distance between Earth's surface and the nearest part of the atmosphere, it can vary depending on factors such as altitude, weather conditions, and the definition of where the atmosphere ends. On average, the Earth's atmosphere extends to around 100 kilometers (62 miles) above the Earth's surface, but it gradually becomes thinner with increasing altitude.
So, the "distance between Earth and the sky" is not a fixed value and can vary depending on the context and how you define the boundaries.
