The NVIDIA GRID technology is the best that we have seen for delivering high densities of HD-quality game streams to subscribers.

In these places, construction is held back by slow-growing (Providence, Long Island) or declining (Detroit) populations or by already-high densities and building restrictions that leave fewer options for new construction (Orange County, CA).

Their overlap confirms the hypothesis that dark matter is the skeleton upon which visible matter is supported, and also lends weight to a second idea that galaxies form where dark matter accumulates at high densities, pulling visible matter with it.
