It is epic because he predicted this before any of the technical wizardry was even in existence.

So, sure - the proof may not be epic -- but the prediction certainly is, especially even moreso that he is correct (again)

Einstein was so brilliant that his very name became a popular cliche. And yet, the more modern science digs into his theories, the more we see that, if anything, his brilliance is still underrated.

The precision they manufactured those things was pretty epic, too.

It's important to realize these predictions were not all separate things - where he just said "Oh hey, what about X?"

He developed mathematical models for currently available observations. Those models in turn also suggested other phenomenon that could not be measured at the time. As time went on, some of these have been measured and found to hold true, others observations about the universe have been had that suggest they don't hold true in all cases (eg: "dark" stuff)
