Eternal change on cosmic scale and solar radiation estimates
The article discusses perpetual change in nature from mountains to celestial bodies. It notes no fixed uniformity in earth or sun dimensions, argues change is too slow for human perception, and cites a hypothetical: if all solar system matter moved from edge to sun center, it would produce heat for billions of years.

Earth’s ancient age debated by scientists and geologists
The article surveys estimates of Earth's age from Darwin and Lyell to Wallace and Newcomb, discussing life’s duration, water existence, and rock formation rates. It explains tidal effects between Earth and Moon, historical spin rates, and how erosion and nebular theory shape time scales, with figures ranging from tens of millions to hundreds of millions of years.
