Red and Blue
The image shows the cosmic microwave background fluctuations. The cosmic microwave background radiation is a remnant of the Big Bang and the fluctuations are the imprint of density contrast in the early universe.
I sort of imagine a similar map of the people around me, the society in which i happen to live. Since the velocity of a wave depends on the density of the medium, the different density areas show the different velocities with which a gossip moves from one mouth to the next. The red regions, the 'hot' ones, are the group of people where the speed of gossip is the highest, and everyone knows everything the minute it is practically uttered. It is the 'no privacy', 'snoopy noses', 'get humiliated' and 'have a laugh' zone. The blue regions are the groups of people where the speed of gossip travel is minumum, and the word of mouth takes quite some time to reach there. Their "current affairs" is what the red regions consider "ancient history".
'X is dating Y, you know' says a person from Blue, while the person from Red already knows that X had dumped Y last year and is now on Z to complete his/her alphabetic series of flirts, and is planning to make a move on A to start the alphabets again.
But hey, you would think, whats the point of all this? There is no point actually... just amusement, i suppose. Next time you find yourself surrounded by society, notice what the people are talking about, and plot a density graph of 'Red' and 'Blue' for yourself, and relish the amusement. :)
