The Grandfather Paradox - The Inconsistent Causal Loop

Welcome back to TARDIS Talk, my good followers of time travel!

So, for the last few weeks, we have been exploring the methods of time travel, but now, I will be reviewing with you vital information that I probably should have explained to you before I even started on how to time travel. We will want to - need to - know about the very mind boggling paradox of time travel: The Grandfather Paradox.

I went around, scoping about information to further explain what this famous paradox is. Upon finding the Time Travel Philosophy website, I found what I needed to explain how the Grandfather Paradox works. I literally had to read this about 10 other times to fully understand how this whole system of cause and effect works.

Basically, what this paradox states is that when you go back and time and take part in an action that contradicts you and your present, the universe, in all its splendor of space and time, will not allow it. Confused? Well I was too. Let's put it into an example.

Now, imagine you are a genius who finally created the first ever successful time machine and at the same time you hated your grandfather for no apparent reason. The next thing you know, you buy a gun, you get into your time machine, go back in time to whenever your grandfather was a young man, face the old-young man himself, and point the gun at him. Now, here is things start to get a little tricky. What happens when you pull the trigger? There are two ways that I can see this go down.

1. The gun fires and kills your grandfather instantaneously. You achieved what you were after. However, from killing your grandfather, you also indirectly killed your father, which also means you could not have been conceived and have been born to kill your grandfather back in time. So, if you haven't been born, then your grandfather will still be alive so that you could still be born to kill him again?

2. You pull the trigger, but something happens. Like I said earlier, with this kind of situation, the universe will not let a contradiction be set, so you can't kill your grandfather. Maybe you miss, maybe the gun malfunctions, maybe someone killed YOU in the midst of it all, but something will happen that will not let you kill your grandfather for a paradox to occur.

Does your head hurt yet? You see, this is what you call an Inconsistent Causal Loop which is basically a vicious cycle, all directed from a contradiction - a paradox - that just can't happen. 

With this information, I'm having very serious thoughts on how I would go about time travel, if it was actually successful that is. But this tells us that we cannot mess with the reality of time or else something on a universal level will erupt, all because you decided to mess with the cause and effect of the universe. 

Thank you for coming to join the discussion of time travel in TARDIS Talk! I hope I didn't make you cry in this blog, because I know how confusing and mind boggling it is, but bear with us for a little bit longer, because it's all going to get EVEN MORE CONFUSING.
