There are many questions about the nature of time. What is time? What causes time? Why time slows in gravity? Why time slows in motion? Is time a dimension? Aristotle may have come closest to understanding time when he speculated that time may be motion. He however added that motion could be slower or faster but not time. Aristotle did not have the privilege of knowing about Einstein’s relativity in which time also becomes amenable to change. Similarly when Einstein was working to develop theory of general relativity and proposed the revolutionary idea that mass curves space he did not know that the universe was expanding. This discovery by astronomer Edwin Hubble came 13 years after Einstein had published his theory of General Relativity. Had Einstein known of this great discovery he may have incorporated these ideas into his theories. Conceptually it is easier to derive space curvature in an expanding universe as an area of slower expansion under the influence of gravitons. One of the most dramatic aspects of the universe is that it is expanding and the presence of motion, forces and curved space-time happens in the expanding space.Bit complex?? Again same situation as 'what is the meaning of life'. Many theorists have different ideas. Looking forward to explore them in more dept.
The meaning of life constitutes a philosophical question concerning the purpose and significance of life or existence in general. This concept can be expressed through a variety of related questions, such as Why are we here?, What is life all about?, and What is the meaning of it all? It has been the subject of much philosophical, scientific, and theological speculation throughout history. There have been a large number of answers to these questions from many different cultural and ideological backgrounds.The meaning of life is deeply mixed with the philosophical and religious conceptions of existence, consciousness, and happiness, and touches on many other issues, such as symbolic meaning, ontology, value, purpose, ethics, good and evil, free will, conceptions of God, the existence of God, the soul, and the afterlife. Scientific contributions are more indirect; by describing the empirical facts about the universe, science provides some context and sets parameters for conversations on related topics. An alternative, human-centric, and not a cosmic/religious approach is the question "What is the meaning of my life?" The value of the question pertaining to the purpose of life may coincide with the achievement of ultimate reality, or a feeling of oneness, or a feeling of sacredness.AGREE OR DISAGREE??
