Meaning of life  The meaning of life, or the answer to the question: "What is the meaning of life?", pertains to the significance of living or existence in general. Many other related questions include: "Why are we here?", "What is life all about?", or "What is the purpose of existence?" There have been many proposed answers to these questions from many different cultural and ideological backgrounds. The search for life's meaning has produced much philosophical, scientific, theological, and metaphysical speculation throughout history. Different people and cultures believe different things for the answer to this question. The meaning of life as we perceive it is derived from philosophical and religious contemplation of, and scientific inquiries about existence, social ties, consciousness, and happiness. Many other issues are also involved, such as symbolic meaning, ontology, value, purpose, ethics, good and evil, free will, the existence of one or multiple gods, conceptions of God, the soul, and the afterlife. Scientific contributions focus primarily on describing related empirical facts about the universe, exploring the context and parameters concerning the "how" of life. Science also studies and can provide recommendations for the pursuit of well-being and a related conception of morality. An alternative, humanistic approach poses the question, "What is the meaning of "my" life?" Questions about the meaning of life have been expressed in a broad variety of ways, including the following:  These questions have resulted in a wide range of competing answers and arguments, from scientific theories, to philosophical, theological, and spiritual explanations. Many members of the scientific community and philosophy of science communities think that science can provide the relevant context, and set of parameters necessary for dealing with topics related to the meaning of life. In their view, science can offer a wide range of insights on topics ranging from the science of happiness to death anxiety. Scientific inquiry facilitates this through nomological investigation into various aspects of life and reality, such as the Big Bang, the origin of life, and evolution, and by studying the objective factors which correlate with the subjective experience of meaning and happiness. Researchers in positive psychology study empirical factors that lead to life satisfaction, full engagement in activities, making a fuller contribution by utilizing one's personal strengths, and meaning based on investing in something larger than the self. Large-data studies of flow experiences have consistently suggested that humans experience meaning and fulfillment when mastering challenging tasks and that the experience comes from the way tasks are approached and performed rather than the particular choice of task. For example, flow experiences can be obtained by prisoners in concentration camps with minimal facilities, and occur only slightly more often in billionaires.
