Bootstrap Paradox

 Bootstrap Paradox is a theoretical paradox of time travel. It occurs when an object or piece of information sent back in the time becomes trapped within an infinite cause - effect loop in which the item no longer has specific point of origin, and is said to be “uncaused" or “self - created". 

To understand this paradox let's take an example:-

 Suppose a time traveller travelled back in the time and taught Einstein about the Theory of Relativity before returning to his own time. 

Einstein claims it's own work, and over to the following decades the theory is published countless times until a copy of it eventually ends up in the hands of the original time traveller. Who takes it back to Einstein begging the question “ Where is the theory originated?".

Then who discovered Theory of Relativity?

1.Bootstrap Paradox problem imposed here is solely based on information.

2.But it is also applicable on an object and person also. If the traveller left a book in which theory is imprinted then that book has no origin.

3.Case of person we have seen in movie predestination in which he himself born himself and killed himself in this loop.
