A Solution To The Grandfather Paradox

In summary, the conversation discusses a solution to the grandpa paradox in which a man from the future travels back in time to shoot himself, but is unable to do so due to the consequences of changing the past. The theory also suggests that free will is an illusion and that the past and future are predetermined. There is a disagreement about the consequences of the man's existence being deleted and the impact on the universe. The conversation also touches on the idea of small actions causing significant changes in the universe.

Hey There,

I would like to share something that crossed my mind the other day, a solution to the grandpa paradox.

My solution is quite basic,
The Man in the future is going to shoot himself in the past through a portal, He will not do so because if he did, he wouldn't exist in the future to shoot himself in the past. But by any probability and all the power in the universe, he does shoot himself, his existence is deleted and the universe functions in balance again.

Free will is merely an illusion.Another theory of mine states that the past and the future are all predestined in the Universe.

What does "his existence is deleted" mean? What about the whole universe that interacted with that person?
That does not work.

Note that you don't have to shoot someone (or yourself) to run into trouble. Even changing the orientation of a single molecule could lead to an inconsistent universe if none of the many possible resolutions is present.

What is the Grandfather Paradox?

The Grandfather Paradox is a thought experiment that explores the implications of time travel. It proposes a scenario where a person travels back in time and kills their own grandfather before their parent is conceived, thus preventing their own existence.

What is the proposed solution to the Grandfather Paradox?

The proposed solution to the Grandfather Paradox is the idea of a multiverse. This theory suggests that when a person travels back in time, they enter a parallel universe where their actions do not affect their own timeline. In this way, the person can kill their grandfather in the parallel universe, but their own timeline remains intact in their original universe.

What are the criticisms of the multiverse theory as a solution to the Grandfather Paradox?

One of the main criticisms of the multiverse theory is that it is currently unprovable and relies heavily on mathematical models. Additionally, some argue that the concept of parallel universes raises more questions than it answers, such as how these universes are created and how they interact with each other.

Are there any other proposed solutions to the Grandfather Paradox?

Yes, there are other proposed solutions to the Grandfather Paradox, such as the Novikov self-consistency principle and the branching timelines theory. However, these solutions also have their own limitations and criticisms.

What impact does the Grandfather Paradox have on the concept of time travel?

The Grandfather Paradox highlights the complexities and potential paradoxes that arise when considering the possibility of time travel. It challenges our understanding of cause and effect and raises questions about the nature of time itself. It also has implications for the concept of free will and the idea of changing the past.
