Flavour changing neutrinos give insight into Big Bang: The question of why are we here perhaps means different things to different people, but in the field of particle physics it is a question that we may be close to finding an answer to. Experimental results presented to the 27th International Conference on Neutrino Physics and Astrophysics (Neutrino 2016) last week could explain the tiny differences in matter and anti-matter that allow the Universe to exist. If we take ourselves back about 13.82 billion years ago the Universe was just being created at the point of the Big Bang. According to our current understanding of physics there was an equal amount of matter and antimatter. But this provides a problem, because when a matter particle meets its antimatter counterpart they disappear leaving behind just a flash of energy. None of us should therefore be here and in our place there would just be a Universe consisting of nothing but light. Somehow, one 10 billionth of the matter that was created managed to survive and makes up everything we see around us today. To explain why this small amount of matter managed to survive physicists have been looking for a tiny difference between matter and antimatter. The neutrino, a fundamental building block of all that is around us, appears to be showing this difference. more...... http://www.sciforums.com/forums/astronomy-exobiology-cosmology.6/create-thread
