“Sadly, the way it works means that he will never be able to fulfil his original wish - to warn his father about his deteriorating health.”
This guy is brilliant and it would be fascinating to see his invention work.
But I think he missed the main point. His father would not change his behavior even if someone from the future went back to warn him. It’s part of human nature.
And IMHO that one fact overcomes all of the power of quantum physics.
I have a bookmark which says “Why do I do what I do when I know what I know?” We all do things we know aren’t good for us. We don’t exercise enough, don’t eat the right foods, don’t get enough sleep,don’t get enough sunshine, or we get too much sunshine, don’t drink enough water, or too much water, don’t brush our teeth well enough, or too well. We play games that put too much stress on certain vulnerable joints, we take chances in our driving. We say things we ought not say, think things we ought not think. And part of it is simply the deep-seated idea that if we lived according to all the “right rules” (which are changing all the time, by the way), our quality of life would negate any increase in its duration.
You never heard of a life altering event?
Having your son visit you form the future might just be such an event (supposing that you could be convinced of that fact).
What is missing from this article is the fact that in Professor Mallet’s theories on time (I’ve heard him speak at length on his theories before) is that your trip to the past is one way. Once your there your stuck there.
