If one applies the General Theory of Relativity to social space, one can see that the shape of space makes people move, and the gravity of the social shapes space. Thus, people have social gravity, and when they congregate, more people are drawn in by this social gravitational field. Sometimes people from blurred areas can experience this social gravity field and congregate on an event from different idea economies. For instance, a Linux programmer can be drawn into the same Youtube video clip as a law student as well as a fry cook. I consider areas of great social masses to approximate black holes.


Widely adopted products are black holes of attention, with event horizons of being "keeping up with the Joneses". The event horizon of the event can be relational in real life or in digital life. A link can be provided by a friend online, (via a blog, instant message, or e-mail). A piece of hardware can be envied and researched outside of digital space, or the digital space can be used to learn about and purchase the device.
The shape of space makes people move, and the gravity of social attention shapes space. Individuals in a network have social gravity, some greater than others. When they move through a social network, more people are drawn in by this social gravitational field. With enough attention, areas of great social mass become approximate black holes, drawing thousands of views to a single web page or object.

Definition

The shape of space makes people move, and the gravity of social attention shapes space. Individuals in a network have social gravity, some greater than others. When they move through a social network, more people are drawn in by this social gravitational field. With enough attention, areas of great social mass become approximate black holes, drawing thousands of views to a single web page or object.

How the metaphor works

Gravity is the right analogy for three specific reasons.

Mass attracts mass. Attention accrues to things that already have attention, and the rate of accrual rises with the amount already held. Robert Merton named this the Matthew effect in 1968, and network scientists later described the same behavior as preferential attachment: a new node joining a network is more likely to connect to a node that already has many connections. Neither mechanism requires the popular thing to be better, only for it to be visible first.

Gravity falls off with distance. Social gravity does too, though the distance is measured in hops through a network rather than in metres. A person two connections away from a high-mass node feels its pull; a person twenty connections away does not.

Mass curves the space around it. This is the part the definition above gets at with "the gravity of social attention shapes space." A sufficiently large node changes the paths available to everyone near it. Conversations route through it, other people position themselves relative to it, and the shape of the surrounding network is determined by where it sits.

Where the metaphor breaks

Physical gravity is symmetrical. Two masses attract each other in proportion to both. Social gravity is not. A node with a million followers pulls on each of them and is pulled on by none of them individually, which is the asymmetry described in Local vs. Global Connectivity.

Physical mass is also conserved and social mass is not. Attention can be manufactured, purchased, and destroyed, and a node can lose all of it in a day. The black hole comparison is useful for the accumulation and misleading about the permanence.

Interface as terrain

The first sentence of the definition is the more useful half, and it is the one most often skipped: the shape of space makes people move.

An interface is terrain. What is placed above the fold, what is default-on, what requires one click versus four, and what is ranked first all determine where people go, in the same way a valley determines where water goes. Designers set the topography and then read the resulting movement as preference.

This is where social gravity stops being a metaphor and becomes a design decision. A ranking algorithm that sorts by engagement is a machine for concentrating mass, because it routes new attention toward whatever already holds attention. The concentration is not an emergent property of human nature. It is the predictable output of a sorting rule, and a different rule produces a different distribution.
