Something is seriously wrong with gravity, and nobody's quite sure why. The problem is that gravity is too weak. Out of the four fundamental physical forces in the universe-gravity, electromagnetism, the strong force, and the weak force-gravity is by far the weakest. It's so weak that, for instance, a pair of tiny magnets can easily overcome the gravitational pull of the entire Earth. There's no particular reason why gravity should be so much weaker than the other forces. Physicists have attempted to explain this discrepancy in a number of ways, from complex theories like string theory to philosophical ideas like the anthropic principle, which answers the question of why gravity isn't stronger
New research suggests that it is possible to create a new form of light by binding light to a single electron, combining the properties of both. According to the scientists behind the study, from Imperial College London, the coupled light and electron would have properties that could lead to circuits that work with packages of light - photons - instead of electrons. It would also allow researchers to study quantum physical phenomena, which govern particles smaller than atoms, on a visible scale. In normal materials, light interacts with a whole host of electrons present on the surface and within the material. But by using theoretical physics to model the behaviour of light and a recently-discovered
