I enjoyed the movie as sci-fi escapism. I knew that there were some scenes that I questioned based on my limited knowledge of physics but I did not go to see Ad Astra as a precursor to qualify entrance into MIT. I went to be entertained and with that experience, I was content. I did have an issue with the travel time and distance from Neptune to Earth. 2.7 billion miles of travel which appeared to take less than 6 months would have meant the Brad Pitt character would have had to clock a distance of 15,000,000 miles/day. In a 5 year period, you're looking at 1,516,854 miles/day and so on. I guess science and engineering in this movie had achieved some very extraordinary technical advances.
