Apparently, electron is not a perfect sphere. You might say what difference does it make if its not symmetric by 10E-27 th extent, but hell broke loose to all the scientists after researchers at Imperial College London discovered this fact. Physicists say that this tiny difference - so tiny that if the electron is magnified to the extent of solar system the symmetry would be lost only to an extent of human hair - might make a lot of difference in terms of the interactions electron makes around. After years of all those science classes in school and college where my teachers over and over tried in drilling down various formulae, radius and size of these atomic and subatomic particles, now I find this discovery fascinating.
And, they say this slight difference might be one reason why it is difficult to manifest antimatter. I hope Dan Brown is updated with this article. This might help him build script for a sequel to his book Angels and Demons, in which the protagonists save the world from destruction due to antimatter. Danny boy, have you started working yet?
