" what is the meaning of life? "

---

During a Q&A session Astrophysicist, Cosmologist Neil deGrasse Tyson answers six ( and three-quarters ) year old Jack's question, "what's the 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 a large number of 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. Although, to be sure, creature comforts can be highly motivating from time to time, a life filled with nothing but the hedonistic search for feel-good experiences can leave people feeling empty.

Science also studies and can provide recommendations for the pursuit of well-being and a related conception of morality.

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.
