Question:
In the text, it is stated that if dark matter consisted entirely of WIMPs of mass 60 GeV/c2, the number of WIMPs passing through each square centimetre of the Earth’s surface would be of order 105, with velocities of order 2 × 103m/s. Use these assumptions to deduce the approximate value of the local density of dark matter and compare it to the average dark matter density of the universe.
