Google has a new easter egg in their search results, just search for [thanos] and the search results will start to disappear. I created a video capture of this in action - of course.
Here it is in action:
You can even see at the end, the number of results under the search bar is changed to show fewer results.
I don't know if this is in any way a paid thing with the Avengers: Endgame movie or not. And as of now, I have not seen the movie. I probably will when I am on a flight somewhere that offers this as a movie option. Otherwise, I will not see it.
This easter egg was mentioned to me dozens of times over the period of time I was offline last week.
