“View the Milky Way at 10 million light years from the Earth.

Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree… After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons”.

Starting from

100 million light years (i.e 10 to the power +23 meters)

to

100 Attometers (i.e 10 to the power –16 meters)
