If Infinity War picks up shortly after Black Panther, then the world will likely still be in shock from the revelation that an isolated country in Africa is the most technologically advanced place on Earth.
Regardless, this moment will likely have huge implications on the next film and the broader MCU.
What we don’t really know is how long after this Avengers: Infinity War will pick up.
Based on how Black Panther opens, we know that the movie takes place more or less immediately following the events of Captain America: Civil War.
