The Possibilities of Time Travel
The most reputed of our scientists are still debating the possibility of time-travel. Many are of the opinion that we should not discard such theory. It doesn’t seem on the verge of realization and so far we have seen nobody from a faraway past or the future. The notion hides two possibilities that, to my knowledge, have never been expressed before: 1) If our future has been changed by entities from the future, all we see is the new future. This future could be modified as many times as these intelligences would keep traveling back to our past or present. 2) The reality we perceive can be modified at will, this new reality totally eclipsing the former one. Such a notion brings about the idea that there could be no past and no future. These human perceptions then becoming void of real meaning; our past could be our future and vice versa.
The situations I just evoked are not as preposterous as they seem at first glance. For many hours each day we dream of events and situations that have no consequences in our state of wakefulness. Most of them are totally forgotten even before we switch back to awareness.
If, according to some time-space theorizers, it is possible to live back our lives or parts of it, it also becomes possible to modify these parts, erase the errors we have made and replace them with more noble and glorious achievements. Of course, according to the same notion, one can see his future. If the future and the past can be confounded, it could mean that time is a notion very different that what we, humans, perceive.
I’m not as sure as I was in my younger days that my past life must be considered as seriously as I did. What I considered a frozen reality could very well be improved in the future. In the process, all my mistakes would be corrected and replaced with more gratifying stuff.
One interesting point in the notion of time travel is that it creates for us the possibility of correcting our errors of the past while projecting the new reality in the future. The idea is consistent with the view that life is a learning process.
According to Stephen Hawking, this learned English I mentioned previously, the subject should be discussed without their debaters being exposed to scorn. The idea I just exposed may seem a serious contradiction of the theory that everything is subject to evolution but a semantic trap is no reason to discard any idea that contributes to our education and evolution.
