When Hollywood Stars Ask About the Universe

Steven Spielberg wanted to know about the gap inside an atom. Not the distance between the nucleus and the electron—he understood there was empty space there—but whether that gap could be used to travel faster than light. Neil deGrasse Tyson had to explain that the electron doesn't slam into the nucleus because it's also a wave, and its wavelength determines how much space it needs. The gap is enormous on atomic scales: imagine two popcorn kernels in the middle of a stadium, with the rest of the volume being the space where electrons roam. But that emptiness doesn't give you a shortcut. What Spielberg might have been circling toward was quantum tunneling, where particles cross barriers instantaneously, or quantum entanglement, where paired particles affect each other faster than light. Neither lets you travel through the gap between nucleus and electron. The first physicist to realize how much empty space atoms contain, Ernest Rutherford, was reportedly afraid to step out of bed the next morning, worried he'd fall through the floor.
