The vast difference between the age of the universe and the relatively short duration of our individual lives can be attributed to the scales of time involved. The universe is estimated to be around 13.8 billion years old, based on current scientific understanding. This immense time span encompasses the formation and evolution of galaxies, stars, planets, and ultimately life as we know it.
On the other hand, human lives typically span several decades, which is a very brief period compared to the age of the universe. Our perception of time is limited to the human scale, and our lifetimes are just a fraction of the cosmic timescale.
The difference in duration between the universe's age and our individual lives can sometimes lead to feelings of insignificance or existential contemplation. However, it's worth noting that our existence within this vast universe allows us to explore, experience, learn, and contribute in our own unique ways. Our brief lives can be filled with meaning, connections, and personal growth, even if they are relatively short compared to the age of the cosmos.
Moreover, our understanding of the universe and the passage of time is influenced by the perspective and context we have as conscious beings. While our individual lives may be fleeting, the impact we make, the relationships we build, and the knowledge we gain can have lasting effects that extend beyond our own lifetimes.
