Quantum mechanics can be hard to grasp, even for the physicists who use it every day. As a result, people have argued from the very birth of the field about what's really going on in quantum mechanical systems. To some extent, it doesn't really matter how you interpret things, provided everyone gets the same answers when they solve a physics problemThe plot of the movie Hot Tub Time Machine relied on the Many Worlds physics view of time travel. A new quantum mechanical approach may let us check […]
Is the universe infinite? Or is it confined to a finite amount of space? Is it shaped like a donut, or does it stretch on forever as an infinite plane? A lot of people wonder about these questions, and a few people are actually trying to answer them. Like astrophysicist and cosmologist David Spergel of Princeton University. He and his colleagues are looking for clues about the shape of the universe, because they think it could help them determine if the universe is finite or...something […]
Fifty two years ago this week, the world was gripped by the unfolding drama of the Cuban Missile Crisis. Most of the world remembers it as a showdown between President John F.
