In this film blog, we are going to analyze the use of wormholes for travelling in the movie. So the question is: Can the astronauts use wormholes to travel long distances? The answer is probably not.
Wormholes are theoretical tunnels through the fabric of space-time that could potentially allow for faster travel between long distances. While wormholes are possible according to Einstein's theory of general relativity, these voyages are purely science fiction. But why? It has to do with a wormhole's instability. If you don't have anything threading them to hold them open, then the walls will collapse so fast that nothing can go through them. While it is possible to hold them open, it would require a lot of energy.
Also, traversable wormholes cannot occur naturally. But in interstellar, there is a wormhole near Saturn that was created by mysterious being.
