The Grandfather Paradox
We think a situation creates a paradox, but it really doesn’t. Host Henry Reich of minutephysics says the Grandfather Paradox is a good example. “What if you went back in time and killed your own grandfather?” he says. “Would you still be born? Or would you have thus killed yourself?” Reich explains the solution and tells us what physics, complexity theory and computer science have to say about this famous, murderous, time-travel paradox.
