I am aware than it is impossible to prove anything in real life. Therefore we can't prove that the picture of the reality we are percieving through our senses is a subjective picture of an objective reality rather than just a dream, virtual reality etc. I wonder if it is possible to calculate, at least approximately, the probability that the objective reality is real? Or is it at least possible to tell what is more probable: objective reality vs. virtual reality vs. brain in a vat (metrix style)? If you could recommend any book or an article on this topic, I would really appreciate it. I would also appreciate some key words/theories that are used in philosophy for this topic.
*(I don't have philosophy background and yet I want to write about this topic, therefore any sources which I could use to support my thesis would be really appreciated)
*(Is there any proof to support my words, that is we cannot prove anything in real life with the absolute certainty - any key word for that would be appreciated)
