Astronomers know more about what dark matter is not than what it actually is.
Dorai Thodla's insight:
Most of the universe is made up of dark energy, a mysterious force that drives the accelerating expansion of the universe. The next largest ingredient is dark matter, which only interacts with the rest of the universe through its gravity. Normal matter, including all the visible stars, planets and galaxies, makes up less than 5 percent of the total mass of the universe.
Astronomers cannot see dark matter directly, but can study its effects. They can see light bent from the gravity of invisible objects (called gravitational lensing). They can also measure that stars are orbiting around in their galaxies faster than they should be.

"At the moment reputation is largely determined by the quality and ultimately quantity of back links but I believe Google are moving towards assessing whether a site should rank based on the authority of the author, how socially shared it is in addition to how well linked it is.
So if you want your website to rank you’ll need to think about how you can make progress in all three of these areas. Unless there’s a dramatic shake up in the relationship between the major social services and Google the best data they have access to is their own network, which I think justifies taking the platform seriously. But before we get to that stage social is already heavily influencing natural search results".
