If you live in an appartment and you are above the 1st floor and your city regulations allow it, you could try hanging sound reflectors around your windows, so that sound coming from below may bounce back to the street. Lateral view: Window --> |/ -- Reflector. Play with the position angle to get the best compromise between view of the outside and level of attenuation. Different materials and thicknesses will work best for different frequencies, being bass the most difficult to reduce.

+ - Gravity Theory Mod May Rule Out Dark Matter 2

pupitetris (1259782) writes "Newton may prove himself right again when he stated that we should better find the forces that explain the movement of the stars, rather than claiming the existence of misterious and undetectable substances: S. Mendoza and X. Hernandez, two mexican astrophysicists, postulate a modification to the equation of the theory of gravity that explain the current observations of large-scale phenomena that couldn't be previously explained using gravity alone, while still retaining consistency with medium and small scale observations. This renders the Dark Matter theory unnecessary, and provides a cleaner and more ellegant solution to outer-space observations that have startled scientists for decades."
