Time Travel?

I have been thinking of time travel ever sence i saw back to the future... I have found flaws in the time travel possibilities, and the times changing, bla bla bla. Now, im not saying it was a bad trio of films, because they were awesome. I loved all 3 of them, not so much # 3, but thats not the topic now. What i understood was this though:
The smallest things can change the present and future when altered in the past. True, but according to BTTF, its only okay to alter your past when you dont like your present. Like when Marty teaches George to stand up for himself and KO Biff. The passion between Loranne and George never existed, it was ORIGINALY out of pity. George was supposed to be hit by Loranne's father in the car, but when Marty did, obviously, it needed to be fixed... So Marty did what he thought was right and, yeah, the above, George and Loranne fall in love, and George isn't a spineless pushover anymore, and Biff is George's little bitch. Awesome.

But it was an alternate reality. Alternate timeline. But Marty and Doc stay...
Lets not forget the almanac portion...
Marty buys an almanac for the sporting events in the future, for his time, so he can win some money. Ok, cool. For you, bro. Doc throws it out, Old biff finds it, and gives it to himself in 1985. Doc and Marty go to "the present" only to find it is GH-ET-TO! Oh, snap! we dont like this, George is dead, Biff and Loranne are married, Biff is filthy rich, and Doc is condemed to a psyche ward. (or something) Well, we can't have that now can we? We dont like that Biff has a good life and ours sucks... Let's make him miserable again.

So they go to the time Biff gives young Biff the almanac, and Old Biff thinks he sucseeded, and brings the DeLorean back to the future where he got it. (How the old coot figured out HOW to operate the time circuts to get there and back, along with the hover adaptations are beyond me)
Marty gets the almanack back and destroys it. - Wait... If Marty destroyed the almanac, the alternate reality never was supposed to exist anyway, because history already had them succeed.
Not realy a thing but its a nice thing i noticed. In #2, Biff watches a Clint Eastwood movie in the hot tub. "Bullet Proof Vest" thing... Marty re-inacts it in #3, which (my theory) was supposed to imply that Marty WAS Clint Eastwood (int he cowboy movie anyway) and founded the Legend, and the bulletproof vest, when Marty was the one who saw it in a movie (in his time) and never knew He was watching himself being re-enacted from the past.
ok, ok. With THAT being said...


Lets go back to the part where the almanac created a "Biff controled" timeline that skewed off the original time line. Remember that?
Ok, well that how time travel would be EVERY TIME. Once you go to the past, you changed history already, and your initial timeline may not be able to be re-entered.
I use this example:
In timeline 1 (TL1) I go back to Jurrasic times and step on a lizard. Oops!, creating TL2. I go to the present, of TL2, and for some reason frogs are extinct. Well i like frogslegs, so i go back to the same time of TL2 when I stepped on that lizard. I tell myself to watch out, and TL1 Me doesnt step on the lizard anymore. Possibly, that would bring TL1 me back to TL1... And TL2 me would have not existed TO tell TL1 Me to look out. Paradox. Space-time continum does its destruction phase. It is possible though that the fabric of time wouldnt do much of anything at all. If i learned anything from all the time travel crap i have seen, and the double negatives and theories of logic, and all that tells me that if somone was traveling through time, it was supposed to happen. All events were supposed to happen. One way or another.

If Lincoln wasnt assasinated, he may have fallen from the balcony. Or runover by a carrage. Many things could have happened to have his life end for a big reason. His life was highly impactful on history. If he had passed from natural causes, it could have been less impactful on history.

So, in sense, traveling through time and meeting your other selves in other timelines may not cause the universe to unravel. For the reason of "all things have a purpose", (unless your purpose as a time traveler happens to be to destroy the universe) or a parralell universe.
This is what Im thinking "time travel" really is. Every time Time is altered, (every travel) a new Paralell universe is created, with the change as the pivot point. Every small thing changes history. Bring back the lizard incident. I missed the lizard. My foot print is still there. i breathed the air, and now, archieoligists are wondering how a dinosaur managed to get a hold of, and fit in a 10 1/2 sized off-brand Vans Skateboard shoe.

The universe isnt just the one universe, it is a cluster of an infinant amount of parallell universes out there. Even parralells of parralells, parralells of those, and THOSE. All of which have small differances, and/or major differences. By meeting yourself within a parralell universe, couldnt cause a paradox, because you are two totaly different versions of yourself within that universe. From this perspective, i can assume that the timeline could look a lot like a spider from above. the body being "reality's timeline" and the legs being the parallels. and hair on the legs being the parralells X2. Or, if you want to look at it like a circut board, you could. the lines of circuts and everything else can easily represent this timeline and alternate demensions. And, of course, all thos little mini-transformers, and things built onto the circitry could be doorways, windows, bridges, all to get from circut A to Circut B, and Back to A.
This could happen, but finding the perfect map, would be impossible within a single life time, or possibly a hundred lifetimes.
This could be the key to creating the time travel device....
The circut board that contains the map of every timeline, every dimension, (alternate, and parallell) along with every gap, bridge, door, window, allyway and shortcut possible all throughout the Full history of ALL universes. Needless to say, it would take a while to figure that out. The flux capassitor concept is seemingly MUCH simpler, but nut likely.
Only Two people I know of have succeded in doing so in their lifetimes... And both are fictional characters. Paradox (Ben 10 Alien Force) Has the entire map of time, universes and demensions in his head, is immortal in sense, and can accuratly "stroll" through time and space.
The second (i just started watching really) is Doctor Who. He is an alien life form, the last of his species, called "Time Lords" he has been inacurate time to time, and needs his Tardis in order to travel. But he sees all that ever was, is, and will be in his head, always. (or how i under stand it anyway)

If you think about it in the sense of alternate and parallell universes, would we have to call the space of which they are al in the Ultraverse? Omniverse? Megaverse? Superverse?

One final thought about the "Ultraverse"...
You know how sometimes we get lost in our "own little world"? well what if we were to dream up of these worlds, and they were actualy being created AS WE DREAMED them? Or, what if we are seing something thats happening in an alternate universe? Or another planet? Every thing we imagine has to come from somewhere... The aliens in tv shows and movies.... Those creatures could have been created from somones alternate world that they found telepathicly. Maybe we do use the other 90% of our prain, and we just chalk it up to a simple imagination?

A few things to think about... Right?
