От атома к Галактике

Animation of a zoom out from the inside of a single atom to the entire galaxy. The first scene shows a single quark, one of three making up a proton (red) in the nucleus of an atom. The nucleus is surrounded by electron shells (blue). The atom is one making up one of the bases (green) in a DNA molecule, which itself makes up a chromosome (X shape) inside the nucleus (white) of a human cell (red). The cell is part of the heart, and the view pulls back from the person’s body showing the streets and buildings of Manhattan, New York City, USA. The pull back continues to show the Earth in its orbit around the Sun, with the orbits of the other planets shown. The Sun is just one of some 500 billion stars in our galaxy, the Milky Way. The Milky Way is thought to be some 120,000 light years in diameter (about zettametres, or metres). The proton has a charge radius of between femtometres, or metres.
