solaris

this film is about a man who goes to a space station orbiting a living star because a close friend asks him to help the personnel aboard, the space station has been suffering from a strange phenomenon which is causing hallucinations, these force the person to see someone they care about,the visions are also physical and makes the whole all deal seem so real. (in the case of the protagonist his dead wife)

what this film questions is does it matter if any thing is real or not because even thought the hallucination have physical form and emotions they are just copies of the original and there for not really the person they are imitating.

at the end of the film the protagonists wife tells him does it matter if we are alive or not, what i think this means is as long as we have a conscience does it matter if we are real as long as we can interact.

in my personal opinion i believe that as long as there is another physical entirety to communicate with you do exist, as Micheal from vsauce points out in his video on conscientiousness what if you took two halves of a brain and put them in to one body each, which would be conscientious, from this idea i believe any  conscientious entirety out side your own form prove you are real.
