The galaxies aren't distributed randomly throughout the universe but they are grouped in gravitationally bound clusters.
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.DNA testing relies on comparing fragments of DNA (called “genetic loci” or simply “loci”) between an alleged parent and a child. A child receives one half of his DNA from the mother and the other one from the father moreover, the process is more or less random.

Arrows represent vector quantities, which have both a magnitude (size) and a direction. For example on Earth, weight acts towards the planet's centre due to the effect of the gravitational field, and has a magnitude in Newtons (e.g. 10N). However, mass is a scalar quantity, meaning that it only has a magnitude - it's just the amount of stuff you have. It would be like an arrow without a direction, which of course is not possible (at least not in this universe...)
