Einstein’s Universe Turns 100

NPR has the article Einstein’s Universe Turns 100. I do not know how to better convey the gravity of the situation other than to quote the starting words of the article.

One hundred years ago, a 36-year-old Albert Einstein presented the complete formulation of the General Theory of Relativity to the Prussian Academy of Sciences. Across the world, events and conferences will be celebrating what is considered, without hyperbole, the most beautiful of physical theories, marrying mathematics with physical concepts in deeply meaningful and elegant ways. Some consider it the highest intellectual achievement in history.

You can probably get a grasp on the theory if you don’t think about it too deeply. Once I start thinking about what the typical illustration of the theory really shows you, that’s when I lose my understanding, somewhat.

Typical illustration of the general theory of relativity

I really have to wonder at this illustration I chose at random from a Google search. I don’t think that ridge at the rim of the canyon belongs there. Terry Steiner, can you explain this to me?
