He led a team to drive a spaceship to outer space to find a new home under the crisis of the sun's imminent destruction. In this process, they experienced many dangers and challenges, and at the same time, they also discovered the status and significance of mankind in the universe. " Interstellar " was about a group of scientists who used time travel to explore distant galaxies in search of a new home for humans. The protagonist, Cooper, was a physicist. He and his team constantly explored the mysteries of time and space and finally discovered a new planet to provide a new living environment for mankind.

They represented two different styles of science fiction, one was the grand exploration and rescue of the universe, and the other was the in-depth exploration of the existence and meaning of human beings.
