But Then Again, WHY?

Time travel had always been a tricky subject for everyone. Its impossibility is more easy to prove than its possibility. But even with this, I still believe that time travel with be possible in the future. Like the video about the different theories of time travel that were shown in the video, I agree that somehow we must not use the term time machine. I believe that a whole being or object is impossible to transmit to a certain period in the future or the past.
Even if we use the concepts that is very technical or scientifically based, it is proven that it cannot be done. When we approach the subject using time and speed, it becomes a very acceptable idea. But like it even said, what makes these concepts impossible is that when speed is heightened into an extreme number, so does mass. There is no possibility that any human travelling with the same speed as light be even alive after a simple experiment and as well, after undergoing the mass increase that is almost 7000x your normal mass.
The proposed ideas as we all know have high possibilities to be spot-on true. So how can one even say that time travel would be possible. I don't know about other people's opinion but I can only see one way. And this is to use data/knowledge transfer. I've seen it in one of the animes that I've watched that this idea even has a higher possibility of success. The reference might not be that reliable but facts were also shown. Transfer of a solid object cannot be possible because it will be turned into something else--something non-living and useless. Data is easier to transfer than the object itself.
But when it comes to the topic of paradoxes and ethical arguments regarding the use of time travel, I only have one response. Why travel to the past and change something that you've done whether it's good or bad rather than try to face your choice? And why travel to the future and see what will happen when there are many possible outcomes of one action that you do? The present is the best place that you'll ever be in. And you just have to live and remember every moment.
