Those answers aren't in the training set, nor is anything like it. It's assembling a correct and general model of physics from examples in the training set, and applying that understanding to be able to solve any arbitrary problem. Nobody knows what "think" or "feel" really mean, and I think this surprising phenomena is a clue to understanding that- it isn't what it seems. Most of our theories about what the human mind, language, and thinking are imply this should be impossible, yet it's clearly not.
