散文在線：如果愛(ài)能穿越時(shí)空
Most Hollywood movies are about romantic love, or at least sex. But Christopher Nolan’s epic movie “Interstellar” has almost no couples, so you don’t get the charged romance you have in normal movies where a man and a woman are off saving the world.
Instead, there are the slightly different kinds of love, from generation to generation, and across time and space.
The movie starts on a farm, and you see a grandfather’s love for his grandkids and the children’s love for their father. (Mom had died sometime earlier).
The planet is hit by an environmental catastrophe, and, in that crisis, lives are torn apart. The father, played by Matthew McConaughey, goes off into space to find a replacement planet where humanity might survive. The movie is propelled by the angry love of his abandoned daughter, who loves and rages at him for leaving, decade after decade.
On top of that, there is an even more attenuated love. It’s the love humans have for their ancestors and the love they have for the unborn. In the movie, 12 apostles go out alone into space to look for habitable planets. They are sacrificing their lives so that canisters of frozen embryos can be born again in some place far away.
Nolan wants us to see the magnetic force of these attachments: The way attachments can exert a gravitational pull on people who are separated by vast distances or even by death. Their attention is riveted by the beloved. They hunger for reunion.
When the McConaughey character goes into space he leaves behind the rules of everyday earthly life and enters the realm of quantum mechanics and relativity. Gravity becomes variable. It’s different on different planets. Space bends in on itself. The astronauts fly through a wormhole, a fold in the universe connecting one piece of space with another distant piece.
Most important, time changes speed. McConaughey is off to places where time is moving much more slowly than it is on Earth, so he ends up younger than his daughter. Once in the place of an ancestor, he becomes, effectively, her descendant.
These plotlines are generally based on real science. The physicist Kip Thorne has a book out, “The Science of Interstellar,” explaining it all. But what matters in the movie is the way science and emotion (and a really loud score) mingle to create a powerful mystical atmosphere.
Nolan introduces the concept of quantum entanglement. That’s when two particles that have interacted with each other behave as one even though they might be far apart. He then shows how people in love display some of those same features. They react in the same way at the same time to the same things.
