That last words a doozy.
Anyways, so I remember in 8th grade when me and my friend use to bulls*** about "theories" related to science -- especialy space, time, and the travel of. Now, I've all ways considered myself a master b's'er, and I was just sitting here recalling some memories of "theories" I came up with.
First the the answer to probability: The odd thing about odds and probability is that there are possible outcomes, and rates of outcomes. Ideally you have a 50/50 chance of landing heads from the flip of a quarter. The problem is, it doesn't always work in a finite state. I've flipped a quarter four times before, and gotten tails four times in a row. Now the odds say that It should be 50/50, but I had 100/0 occurence. How can a universal rule not exist in a specific non universal situation? I mean universal implys all incompassing, so something incompassed - four flips- should be accounted for. I think the real, best answer for this is that of a dimensional paradigm. Any occurrance that can occur, must occur with all others at the same moment in order to balance out universal odds. That is to say, when I flip a coin and I see it land on heads, it too also landed on tails, and the edge. What actually occurs is a dimensional fracture. One continuum branches (kinda like a tree) into several new lines -- each with one of the 3 possible occurances as the bases for that new line.
On this theory, we can assume an infintessimal ammount of branches, and dimensions existing. Each dimension differentiated by a trees of probability.
That being said-I believe time travel is possible by simply navigating dimensions. With this theorem, the grandmother/father conundrum does not occur. That problem makes the assumption that we exist on a single looping space time continuum, and killing your parents parents will negate your existance, negating your act. If we rather instead consider the time continuum based on a fractured tree line the problem doesn't occur. Because by killing your parents parents you are adding a new occurence - fracturing the tree at a higher level- the result will be you not being born - but in a different dimensional time line. The original you is not affected.
Now, rather then actually traveling through time, you are traveling through dimensions that are offset by the possible occurance of when time started.... "wtf?" you ask. Well,
Let us consider an arbitrary beginning of time - lets say the big bang. Everything is nice and united into this ultra dense singularity, we will consider it the top of the tree. At this top of the tree, there are already an infinite number of probabilites (tree branches) that are fractured and created-all denoted by one event - when the big bang happened. Lets imagine for a moment a superceeding time line outside of this system just for us to picture the event. Kinda a stop watch, starting at zero seconds.
So at this big bang, there is an event - the bang, and the specific of it - when. It *could* happen at t = 0 (our superceeded time line), it *could* happen at t = 1, t=2, t=3, t=n. Because all occurances must occur, it happens at all t=n. A branch in this time space continuum is created at every possible infintesimle time incriment. So once branch would have a time of t = 1, while another would have a branch of t = 2038348023840234. Lets call these branch continuums line A, and line B respectively.
Lets assume for a second that by the infinite chance of happening-and therefore must happening, that for every event in either line, they shared the same outcome all except for one important one - when the big bang happend. Time line A has a lead on B, it is 2038348023840233 ahead of B. Lets say thats roughly in our imagined time line 20 years. Lets also say that JOE is a man that exists in Line A, and WILL exist in line B in about 5 years (from B relativly). Now, Joe decides to time travel-in order to accomplish this he simply shift phase with a dimension that has a time offset of the correct maginitude from the original point in time of the big bang. Say he goes to B. So now Joe is AT B, before he is born - automaticaly this causes B to diverge into two sub branches - one branch with the basis of JOE traveling and being iN B, and the other where Joe doesn't, and is not in B. The same thing happens in A, one line he is gone because he traveled, and the other line he is still there going about every day business because he did not go to B. Both lines have diverged and created sub branches. While Joe is at B, the B branch where he is there, he decides to kill the father of his father. B once again branches from the possible occurances, Joes grandfather dieing, and not dieing. From this point on, in the death divergence, Joe will not come to exist (as havin be born by the parents) but will continue to exist (as having travled from a different dimension where he does). No other branch in the continuum is affected by this event - A remains unaltered execept from the divergence of his actual traveling. The second divergence of B will be the only affected line - and things will spiral into complete difference because of this event.
The theory answers the question that you can "time travel", you can travel - but you can't affect your original reality.
So thats a breif rant about some ideas I had. Feel free to share, coment, critique, debunk, or even BullSh** with me. I've got lots of time. PUN N TENDED!!
