article_snippet: And if one scientists gets his way, one of these searches could involve looking for dark matter - one of the greatest unsolved mysteries in the cosmos.
article_snippet: Dr Christoffer Petersson from Chalmers University of Technology in Sweden and two colleagues came up with ’s model to predict the existence of dark matter.
article_snippet: The current ‘Standard Model’ of particle physics is quite good at describing physics on a subatomic level, but particle physics can’t account for dark matter in the universe.
article_snippet: This includes dark matter particles.
article_snippet: When physicists study the dynamics of galaxies and the movement of stars, physicists are confronted with a mystery.
article_snippet: If physicists only take visible matter into account, physicists equations simply don't add up; the elements that can be observed are not sufficient to explain the rotation of objects and the existing gravitational forces.
article_snippet: From this physicists deduced that there must be an invisible kind of matter that does not interact with light but does, as a whole, interact by means of the gravitational force.
article_snippet: Called 'dark matter', this substance appears to make up at least 80 per cent of the matter in the universe.
article_snippet: Standard Model’ of particle physics is quite good at describing physics on a subatomic level, but particle physics can’t account for dark matter in the universe (illustrated).
