Corrected entry: During a mid-credit scene, while traveling in space en route to Earth, the Asgard refugees ship is ambushed by another colossal ship. This, however, should have not happened. Science fiction fans know that ships don't go gallivanting in empty space on conventional drives. Instead, they use a faster-than-light mode of travel method as "performing hyperspace jumps." Moreover, Asgard and Midgard (Earth) are two of the nine realms. There is one hyperspace jump between them.
Corrected entry: How it is possible that, despite Loki being on Sakaar for some time, he seems to have no idea that The Hulk is also on the planet? This is given away by his reaction when he sees Hulk in the arena. Loki also has gotten close to The Grandmaster, and there are images of the Hulk carved into the sides of buildings, but he has no clue that The Hulk is the arena champion?wizard_of_gore
