00:00Imagine entering a machine, pressing a button, and suddenly finding yourself transported 100 years into the future,
00:06or traveling back in time to witness ancient civilizations like the Mayans, the Indus Valley, Gandhara, or the Egyptians.
00:12Could you adapt to life in such an ancient era after experiencing the advancements of a futuristic world?
00:17Or what about a future where technology is leaps and bounds ahead of what we know today?
00:21This concept is famously referred to as time travel, but is it just a product of fiction in books and films, or could it become a reality?
00:28For centuries, the idea of time travel has captivated human imagination.
00:32From H.G. Wells' classic novel, The Time Machine, to blockbuster films like Interstellar, The Flash, Tenet, and Back to the Future,
00:39time travel has been a recurring theme in storytelling.
00:41Interestingly, science hasn't completely dismissed the possibility.
00:45Renowned astrophysicist Neil deGrasse Tyson suggests that we are already experiencing time travel in a linear fashion,
00:51progressing from the past to the present and onward to the future.
00:54But what if we had the ability to control the speed or direction of this journey,
00:58let's talk about traveling into the past.
01:00If it were possible, we might undo mistakes or change the course of history.
01:04However, what if our actions inadvertently caused a paradox,
01:07such as preventing our own existence by altering events like the lives of our grandparents?
01:12The consequences could be catastrophic.
01:14Einstein's theory of relativity indicates that accelerating time is theoretically achievable,
01:18but it would require traveling at speeds close to the speed of light.
01:21The faster you move, the slower time progresses for you.
01:25To simplify, if you boarded a spacecraft and traveled at the speed of light for a decade,
01:29by the time you returned to Earth, 100 years would have passed here.
01:33Essentially, you would have jumped forward in time.
01:35However, the amount of energy needed for such a feat far exceeds what our current technology can handle.
01:40Yet, with advancements in the future, and efforts by visionaries like Elon Musk and others,
01:44such a possibility might not be as far-fetched as it seems.
