Confused by how particles can be in two places at once? Wondering how particles can instantly communicate with each other no matter what the distance? Quantum physics is a field of study that defies common sense at every turn, and quantum entanglement might lead the way in the defying common sense department. Entanglement is the unusual behavior of elementary particles where they become linked so that when something happens to one, something happens to the other; no matter how far apart they are. This bizarre behavior of particles that become inextricably linked together is what Einstein supposedly called "spooky action at a distance."

This new video from PHD Comics provides a combination of live action and animation to try to explain entanglement.

"Not surprisingly, it was really hard to draw this video,"

says animator Jorge Cham

. "How do you depict something that has never existed before? And more importantly, do you draw alligators differently from crocodiles?" Yes, that sentence actually makes sense when it comes to entanglement. And the advice at the end of the video from physicist Jeff Kimble is applicable to entanglement -- and life in general -- as well: "If you know what you're doing, don't do it…"

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
