How long would eyesight travel just seeing a single proton on a leaf from some 10 million light years away–if it’s at all possible? It will probably be something like what is seen in this video.
From the vastness of the Milky Way with billions of stars, the eyesight gets past billions of stars and other solar systems. Then finally our sun appears as a dot, growing bigger until its solar system comes in full view. Then the earth and its orbit. Then the earth’s surface and contours, a forest, a leaf and then the microscopic elements found on it.
