The Matrix did explain how it was technically possible.
Really, how?
It informed the audience that after artificial intelligence was created,
What is the technology behind this artificial intelligence, how does it work?
the machines decided unseat it's creators since we were overly dependent on them once they started to think for us.
Since the technological principles behind this artificial intelligence was not defined, the machines were given some mythology mission in plot (fight against creator... hahaha)
It also informed the audience that our reality can be augmented since our 5 senses operated based on the electrical signals that were fed in to it.
And Inception informed audience that our mind can experience a virtual reality through the faculties of brain (subconsciousness, consciousness and memory) which also work through electro-chemical signals. What's the difference?
Any movie that had time travel as it's central plot, did explain, sometimes vaguely, how time travel was possible.
Follow your logic: Any movie that used time travel must necessarily claim the possibility of time travel. Otherwise it wouldn't rely on such a pilot, would it? Question is this: How? Tell me a movie that gave you the exact scientific knowledge of time travel.
Event Horizon, and De-Ja-Vu are 2 recent examples. Even the movie Dreamscape did a better job explaining how highjacking dreams were possible
.
What was the science and technology we learned from these movies in terms of how to hijack dreams? Examples, methods? Yes?
Says film history. For instance, have you ever watched a Hitchcock movie? The central theme is the suspense; all other weird reasons (which organization is following the main guy and why in North by Northwest, what was the madness behind Kim Novak's character in Vertigo, etc.) are irrelevant to the story, this is the margin left to audience to figure out. But even if they don't, it still doesn't make any harm to the plot.
It was a total copout in my opinion.
So you are still bound to give an example which technological working mechanism or scientific information you obtained from which sci-fiction movie.
It's going to take a quantum leap in technology before we have the technical capability to allow a group of individuals to consciously share the same dream.
It's all about correct representation of electrical signals of the brain. Since you are such an expert from the earlier dream hijacking movies, tell us what kind of technology we need?
However, everything else that appeared in the film seems to indicate that technology in every other sector is the same as it exists today.
Everything you watched could be a dream as well, so it's totally irrelevant which time period is used. Remember Matrix: They were from future, but battleground was 1990s.
Bullshit, theoretical physics is used to explain a lot of things in science fiction movies. At least the ones I watch.
Example? Not for "bullshit" please, for theoretical physics...
