The following closing essay has been kindly contributed by Haresh Khameni, the Managing Editor of the Mechanical Engineering Channel. It is related to the series in that it deals with modern man's view of science as a solution to everything, and the relative dearth of research into human consciousness. In doing so, it touches upon topics discussed by researchers in the areas of causality, entropy, eschatology, quantum theory, anthropic theory, multiverse theory, and Boltzmann brains. The views expressed do not necessarily reflect those of myself.
Science has certain limitations for scientific instruments cannot measure everything, scientific formulas cannot analyze all situations, scientific theories cannot be applied to all concepts, and human beings have not yet been able to discover all the laws of the nature. Most scientific work has been dependent on the external findings based on some studies or previous research, and there are hardly any studies based on human consciousness. Human consciousness is an entirely different world and much more widespread than the external materialistic world. The irony is that scientists don't yet have the know-how to study it in detail.
The important thing to know here is that these worlds can only be experienced by looking inward and that no theories, bookish knowledge, and intellectual discourses are really that helpful. They may serve as guides initially, but they are not an end-in-and-of themselves.
Birth and death are the two most important incidents of the human life and they are highly subtle phenomena. They cannot just be understood by some intellectual concepts. You just can't make a telescope that can see where the person is going after death, for there are an infinite number of places where the person may go after he or she is deceased. You can't use this telescope to see where the person is coming from for there are an infinite number of places where he or she may come from.
