That is, why is there anything rather than nothing? Some even think they make no sense. Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe – more precisely than ever before. According to NASA, after inflation the growth of the universe continued, but at a slower rate. Some dismiss these questions, thinking them idle. “Why is there something, rather than nothing?” could be the oldest and deepest question in all of metaphysics. %PDF-1.5 %���� To investigate why all the antimatter created in the Big Bang didn't just cancel out the matter, the researchers have looked into whether or not the neutron acts like an "electric compass." 27 July, 2011.
