If time travel were possible, but any attempts to change the past were futile because they wouldn't affect the future, it would still be fascinating to visit different eras for several reasons:
Historical Exploration: Visiting the past would provide an opportunity to witness significant events, explore different cultures, and gain a deeper understanding of our history. It would allow us to experience moments that shaped the world we live in today.
Personal Curiosity: Humans have an inherent curiosity about the past. Exploring different time periods would satisfy our desire to know how people lived, dressed, and interacted in various historical epochs. It could also provide insights into our own origins and the development of human civilization.
Learning and Knowledge: By observing the past firsthand, we could learn valuable lessons and gain new knowledge. We might uncover forgotten wisdom, discover lost technologies, or even gain insights into unresolved historical mysteries.
Appreciation of Progress: Experiencing past eras would help us appreciate the progress and advancements we have made in various aspects of life, such as technology, medicine, and social equality. It would give us a perspective on how far we have come and potentially inspire us to continue working towards a better future.
Personal Connection: For individuals with a deep interest in specific historical periods or figures, being able to visit the past would allow for a personal connection with their idols or ancestors. It could be a profound and emotionally fulfilling experience to witness the lives of those who have had a significant impact on our world.
While the inability to alter the future might limit the practical implications of time travel, the opportunity to explore and learn from the past would still hold immense value for many people.
