Uh, weird, but, um, I say time travel is also creepy. Say if I go back in time to 1001. I was born during 1019. I may die from my atoms returning to the state they were in during 1001 before I was alive thus killing me. Even if I don’t die that way, if I die in year 1001, I shall be born AFTER I die and I will eventually travel back and die. This cycle repeats infinitely, locking even my body out of the future.

Is the Grandfather paradox really a paradox? 🙂 Look, a sequence of events take place between your pulling the trigger of the gun and the grandfather’s dying, and they take some time to take place. Your grandfather’s death would erase you out of existence, and threfore make it impossible for you to kill him, only if the grandfather died BEFORE you pulled the trigger. His death erases you from existence, but the bullet embedded in his brain still exists. Still, there are conditions that would make it a time paradox, namely, if the existence of the bullet was dependant on whether the grandfather lives or not. If, for example, the grandfather, or one of his successors was a blacksmith and created the bullet that kills your grandfather, the senior’s death would erase both you, and the bullet from existence. It would be highly improbable for you to use such bullets, which translates into the high improbability of the paradox occuring. However, if you use ammo of any other manufacturer, the bullet continues its existence even if you do not.

In reply to Erik Stengler.

I think it’s a little of both. It’s a bootstrap paradox in that the main character is a person who came from himself. He has no existence outside the time loop. He literally gives rise to himself.

It’s also a Predestination paradox. It’s a ‘temporal causality loop’ in which Event 1 in the past influences Event 2 in the future (time travel to the past) which then causes Event 1 to occur,

A man walks down a street in NYC, enters a telephone booth and calls a cab. The cabby tells him they will be there in ten min, cabby arrives at destination a woman walks up to the cab and complains about how late the service is. Confused and baffled the cabby gives the woman a discount, the cabby drives around the block for twenty minutes never realizing once there was no one in the car. But his pay check just doubled and the his meter reads as never having left the spot.

Please consider these.
You mentioned that the things in the bootstrap and predestination paradoxes occur in a cyclic and never ending fashion and you pointed it as the main problem.
But in the Grandfather paradox you raised a question”Why should I go and kill Hitler as there is no reason and trigger for me to go back if I have already killed him”.If you look up the above sentence carefully you will notice that you(the creator) have tried to connect all these events in a cyclic fashion that you never wanted in the bootstrap paradoxes.

First you didn’t accept the cyclic, origin less events.
Next you mentioned grandfather paradox as a paradox because the cycle is not completed.
Both paradoxes are contradictory ……….

In reply to Jackson. If you're only going to talk about things that are actually definitely possible, how are you going to find out what's possible without science?

This all paradox’s thus explain us that everything is planned for everyone & nothing can change it until something much powerfull than that planner interrupts in between all the plans.

How about the observers? Beings from the future that has traveled to our past and present. In their timeline they have no record of our life so they travel to the past to create a record for their own timeline. Apparently there is some form of catastrophic event that happens and completely destroys all records prior. Are these observers changing our timeline by coming here, or does it not matter due to the fact the upcoming catastrophic event destroys all evidence of their presence in our timeline anyway.

This is why many of us think science is full of shit (besides the fact it keeps changing). Why all this discussion about something that is obviously impossible? Only scientists ….

I believe it would be close to The Multiverse hypothesis in that by traveling back in time, you end up in a parallell universe.
However, this parallell universe is not created neither when you travel or cause a time altering event. Imagine the amount of energy it would take to create it? It’s more likely that paralell universe already existed and whatever action you take in it will follow all natural laws of nature.
To return to your own time line, I can only see two possibilities:
a) Time is not linear and everything that ever has, is, and will, all exist at same time. To then go into the future, you could end up in an infinite number of alternate realities.
b) You can’t go to the future other than the normal flow of time. While you might find a way to get back 10 years in the past, you would have to live in that timeline for 10 years until you back to your “own” time. And that timeline would most likely not be the same you came from.

Finally, would you be able to interact with yourself in a past timeline? Perhaps some weird effects of quantum mechanics would just send you into a timeline where you didn’t exist. Either you died, or you were never born. Your knowledge of the future events would most likely also become false. Perhaps you know the winning lottery number and place all your money on it, only to lose it all. Trying to convince others and people would also be futile if you couldn’t even “predict” future events you remembered.
