I ran across this tidbit. Perhaps everything that's happening is the result of the universe self-correcting. In other words, the universe is attempting to rid itself of any time travel paradox by eventually causing the initial disupting event to never have happened. And that's what the show is about. So the question would be what was the original disrupting event? It may not have happened on the island. It might have been someone at Ann Arbor or Oxford that got everything out of kilter.


Hans Moravec glosses this version of Niven's Law as follows:

There is a spookier possibility. Suppose it is easy to send messages to the past, but that forward causality also holds (i.e. past events determine the future). In one way of reasoning about it, a message sent to the past will "alter" the entire history following its receipt, including the event that sent it, and thus the message itself. Thus altered, the message will change the past in a different way, and so on, until some "equilibrium" is reached--the simplest being the situation where no message at all is sent. Time travel may thus act to erase itself (an idea Larry Niven fans will recognize as "Niven's Law")
