Two brilliant scientists have suggested that Global Positioning System (GPS) used by us for navigation purposes might help understand dark matter, the material which is supposed to make up more than 80 percent of our universe. Dark matter is extremely difficult to detect since it does not interact with ordinary matter too often. Since it has never been studied by science, we do not know anything about its constitution. While some among the scientific community suggest that it is a particle, a new study suggests that it might consist of kinks in the quantum field.
Dark matter is called so because it is invisible and does not reflect light, making it baffling and immeasurable.
