Isaac Newton changed the way we understand the Universe. Revered in his own lifetime, he discovered the laws of gravity and motion and invented calculus. He helped to shape our rational world view.

However, merely observing neutrinos is not enough to draw conclusions about the properties of quantum gravity—we must also look for signs of "decoherence." As they travel through space ...
