Well I’m pretty surprised that this experiment has made its way to the real search results. But Its a cool feature if you are searching for things that can be visualized over time.
It may not work for everyone, but if you are really interested to see what it looks like try adding “view:timeline” at the end of your search query. So search for albert einstein view:timeline in Google and you should be able to see how it looks like.
