Time that has no existence but we just feel it. We are in the middle of the first dimension of time. That is, the past, the present and the future are how we live with time. What we do now is a reflection of the future. This means that, in past people invented computers, so today we can do difficult time-consuming work very easily. Just think, if people didn't make computers then, we wouldn't know anything about the internet today.
That is, what we are doing now will be reflected in us in the future. You must have heard of time travel or time machine. Although we cannot travel in time now, in the future we may have that ability. Now the question is, do we do any wrong thing in the time machine and we can't go to the past and fix that wrong thing.
Just doing this will create some paradox. Today we have a famous paradox, the bootstrap paradox.
Let's find out,
What is a bootstrap paradox?
We will understand this through an example.
Suppose one day you are walking down the street and suddenly a person comes up to you and gives you a picture. That person leaves before you understand anything. When you go to see that picture. Suddenly a car hits you and a few people hit the car a little earlier. You go and see that the person who gives you that picture is the person who hit the car and the person dies.
You go home and see that picture. But did not understand anything. A few years passed. You are about 32 years old then. One day when you see that picture, the glass of that picture opens and some paper comes out of that picture. Many of today's instruments were written on a large piece of paper. And it also wrote how to make a time machine. Then you thought that if I could go through the time machine in the past and give this information to my childhood, then I could be a scientist now.
You went to the time machine in the past thinking that you gave that picture to your childhood but accidentally I was hit by a car and died.
1. The point to look at here is that even after trying, you could not go to your past and fix your present.
2. There is no literal existence of that picture, which means that it is not known who the real picture is.
3. This whole thing is stuck in a time.
In other words, if you prevent your parents from meeting you, you will not exist.
Even if you do, it will be seen that you are the reason for the reunion of your parents.
But if you go in the past and kill your father, then your parents will not be reunited. Then what will be your existence. The question is, can such a thing really be done?
Answer: - This form can be done. In that case you will go to the parallel universe. And there you will kill your father but its effect will happen in this universe.
Now bootstrap paradox comes from
Though thought experiments about time travel date back centuries, the bootstrap paradox comes from Robert Heinlein’s story “By His Bootstraps.” It was published in the October, 1941 issue of the Astounding Science Fiction magazine under the pseudonym Anson MacDonald.
The term bootstrap paradox comes from the title of the story and the idiom pulling yourself up by your bootstraps, a nod to a future version of oneself influencing the life of a past version. As the idiom originally observes, it’s impossible to pull yourself up by your own bootstraps — unless you’re a time traveler.
