I did a simple math today. I have been trying to compare the rates of Earth’s expansion with the apple’s growth. Let us assume that Earth expands globally 4 cm/year. Its diameter is roughly 12,756 km. An apple is maybe ready in 3 months with the final diameter 10 cm.
This means that Earth would change its diameter by 4/1,275,600,000 per year. Now I try to take this fraction and apply it on the apple. We get 0.31 nanometers.
The annual global diameter increase of the Earth is roughly the same as the diameter increase of an apple by 0.31 nanometers. Do we have instruments that are able to decide whether an apple grows when we talk about nanometers?
