The existence of dark matter is already known to the scientists. The dark matter is found to constitute to about 27% of the total mass of the universe. The article has associated the presence of WIMPs (weakly interacting massive particles) within the dark matter. This dark matter is found to clump in the haloes including the own Milky Way. These WIMPs tend to traverse across the solar system and modify the individual trajectories. The co-author of new paper by Samuel Lee in Princeton University has proved that the effects are drastic and there is a gravitational focus when there is a pull of sun on dark matter.
