Time travel ideas always make us go crazy. Who doesn’t want to time travel, if they got a chance either to go through their past or future? When Einstein proposed the theory of relativity, a possibility to travel to the future by moving very fast got established. Time travel to the past is a debatable idea as many scientists oppose it due to many unanswered questions & paradoxes.
What if our entire universe is probably in a tiny glass jar somewhere, placed on a shelf in an alien child’s room as a science fair project that got C-. What if we can reverse time and go back to a singularity.
I would like to think of time travel to the past in a different way. Everyone who is reading this article mostly spends their spare time watching videos on youtube. In youtube, we have millions of videos posted by different channels. It also provides an option to pause or go backward and forward, we can't do anything further. If we take an analogy consider the channels as galaxies & videos to be the life of every one of us.
Similarly, if we can create a device or an energy source through which we can go back in time by a particular time frame. Where the video is from our present moment to the past, we can only pause or move forward and backward. We don’t have any power to change whatever is already done, we can just go through it like going through the book of the universe which we have only read from the later part. I believe this viewpoint can overshadow some of the paradoxes and can act as our source to know the origin of life & the underlying mysteries of the universe.
