Question concerning the meaning of the film Solaris 1972?
One possible reading of the end of Solaris is that the scene back that holds the viewer sees first place in the spirit of Kelvin, then in the spirit of the ocean which collected her thoughts and replays. This would imply that the ocean came to understand his emotions and a form of interspecies communication took place (which would contradict the message Lem that understanding is impossible) … In a sense, it does not matter – one of the many themes explored in the film is the subjective nature of reality. Wherever Kelvin is "really" located at the end of the film, it makes no difference to him. But it makes a difference to me – I want to know what you think or Is it? What is the reality of this scene?
This is similar to another Sci-Fi on a planet that created thoughts into reality. A Robbie Robot movie. I think that Star Trek too used this. I'm reserving its final ruling and I do not think contact could come in any form, even those we may think just because if you do not know about it, then you would not know of its existence. Not really answer your question.
