article_snippet.sent: When physicists study the dynamics of galaxies and the movement of stars, physicists are confronted with a mystery.
article_snippet.sent: 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.sent: 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.sent: What is important is that our will have collisions at energies
article_snippet.sent: At this higher energy level we don't know what we'll see - no-one has looked there before. '
article_snippet.sent: That's a fairly glaring hole in our theory.
article_snippet.sent: Supersymmetry particles are a good candidate, but Supersymmetry particles're not the only candidate. '
article_snippet.sent: Supersymmetry particles also believe Supersymmetry particles could uncover the existence of extra dimensions, which may explain why gravity is weaker than theoretical models would predict.
article_snippet.sent: However, some have expressed concerns that the machine could be seriously unsafe, as the machine high-energy experiments create conditions similar to black holes which could have catastrophic consequences.
article_snippet.sent: Interestingly, the answers to these problems in cosmology might lie in the realm of sub-atomic physics studied at Cern.
article_snippet.sent: Even more exciting is the possibility that the universe could have more than three space dimensions, and that other spaces are hidden all around us.'
