Hello everyone! I recently watched the new Interstellar movie, and have some questions that I would like answered. Warning: Spolier Alert! My questions will contain spoilers, so if you havent seen the movie yet, and plan to do so, leave now. Also, if you are going to rant about the movie, do it somewhere else. I don't care about your opinions. If you don't know the premise here it is: Humanity has discovered a wormhole in our system, and decide to travel through it and find a new planet due to the Earth not being able to support us anymore. The questions: 1. After traveling through the wormhole, the first planet visited is orbiting a black hole. Because of this, time is affected; one hour on the planet = seven years on Earth. How can gravity affect time? 2. Scientists at NASA state that wormholes are not naturally occuring. So I can only assume they are artificial. If this is true, how can a wormhole be generated? Major Spoiler! In the end it is revealed that a future version of humanity generated the wormhole, and that we have transcended space and time. The movie states we have reached the fifth dimension. What is the fifth dimension? And how would we reach it?
