Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

Time Travel

So, your mode of time travel leads to a reality where anything done in the past doesn't matter, since, in a way, your time-line was predetermined and all that you do will be for no purpose, except researching historic events and people?

Also, since the Cylinders would branch off from a certain point, would it be possible for two travels from after the fork meet when traveling back before the fork?

Essentially, yes.

And essentially yes to the second thing. But they won't remember each other, since they never met in each other's home cylinder.

I know. Kind of defeats the purpose of time travel, but it makes the most sense to me. You must admit it's a good way to get around paradoxes.

Yeah, it does sound a good way around it. Except for one thing, if they go back in time and cause a change then technically didn't they just travel into the alternate cylinder slightly? Unless the moment they change something they get pulled away from that timeline into their rightful one.

My idea for time travel is this. Every bit of matter, down to the smallest vibrating hadron, is moving through it's own idependent time-line, consisting of it's own independent history and future. Now, this means that if you go back and time and kill your grandfather, for example, and you came back you DID kill your grandfather. However, you still exist because the history of your particles are the same, your past is the same, but the timeline the rest of the matter in the universe went through was there for subjected to that change.

That could work. But then again, wouldn't only the grandfather's history and past change since only his matter was "destroyed" (I know matter can neither be created or destroyed. I just can't think of another word)?


You do bring up a good point (about my theory). Yes, the moment you change something, you do sort of travel with the timeline you caused. But when you return to your own time or die in the past, you're back in your own timeline. So you really didn't change the past. You experienced the past change and remember it, but it never actually changed for everyone else on your timeline.

Ah, now I get how your time travel works.

Anyway, no, it wouldn't just be the grandfather's time line to change. How do I explain this,... did you ever play marbles when you were a kid?

Imagine a game of marbles, the circle outline of chalk being the universe and the marbles in it is the matter. Now, let's play. I take my marble, Marble A, and catapult it into the game where it hits Marble B and Marble C leading to the interaction with Marble D, you, to start moving (being born).

Crap, forgot to keep score, we better play again.

We start the game over and I move every marble back to where it was. However, I took the Marble D from the original game and put it right between A and BnC. This causes every other marble to interact differently. Then, as the marbles are still moving I pull Marble D out and put it back in after the game is over with back exactly where it was after the first game, only now, all the other marbles are in different places.

Now then, you probably get the metaphor. Basically, every interaction that the marble caused, after it was affected, become different then what they would have been (like the Butterfly affect) however, Marble D remained the same. Why? Because an outside forced caused that, in the metaphor it was the player, in time travel it would be the time travel itself.

All of these theories are great and very interesting I like them though I my self have no personal theory to share because I have no idea what to beleave. Though I do beleave that paradoxs can fix themselves and that their is a multiverse maybe even an omniverse comprised of multiple multiverses.

Maybe time travel can alter history but in the long run the same basic events happened just slightly different or at different times. Like what if some body went back in time and deflected the meteor that wiped out the dinosaurs in my opinion the dinosaurs will still go extinct just gradualy then birds will take over and then mammals with the final dinosaurs going extinct with the ice ages which actually happened sooner for some reason(enviromental factors causing a atmospheric overload of green house gases eventually shuting down the currents maybe?) and then apes which have mostly been monkeys and lemurs get out of the trees as they vanish, with less time for the evolution of great apes and hominids time has made an alteration great apes arise from lemurs and hominids skip great apes and are directly descended from monkeys.

Thats just what I think though I doubt it would actually act like that.

I just thought of a new theory. By going back in time, you would be changing the timeline from the point at which you arrive, simply because you did arrive. In doing so you would cause a new timeline to branch from the old one, meaning the future had not yet been determined because you came back in time and started an alternate universe.

This is what happened in the new Star Trek movie.
We should all aspire to die surrounded by our dearest friends. Just like Julius Caesar.

"The Lord Universe said: 'The same fate I have given to all things from stones to stars, that one day they shall become naught but memories aloft upon the winds of time. From dust all was born, and to dust all shall return.' He then looked upon His greatest creation, life, and pitied them, for unlike stars and stones they would soon learn of this fate and despair in the futility of their own existence. And so the Lord Universe decided to give life two gifts to save them from this despair. The first of these gifts was the soul, that life might more readily accept their fate, and the second was fear, that they might in time learn to avoid it altogether." - Excerpt from a Chanagwan creation myth, Legends and Folklore of the Planet Ghar, collected and published by Yieju Bai'an, explorer from the Celestial Commonwealth of Qonming

Well that is what I would expect would happen. History does not have someone from the future in it, so nobody can go to our past.

So time travel is a fruitless endeavor then? Damn, two centuries of speculation all for naught.

Time travel is too complicated. I'll just stick with time dilation. Go into space a few years, come back and turns out to be a few decades. I think that was used in the Planet of the Apes book.
I wish I could give the public a true picture of the queen as she appeared at her best, but this would be impossible, even had she permitted a photograph to be taken, for her charming play of expression while in conversation, the character and intellect which were then revealed, were only half seen when the face was in repose. -Lilias Underwood when speaking of Empress Myeongseong

"I was born in the dark. I went out into the light, and your Majesty, it is my displeasure to inform you that I have returned to the dark. I envision a Seoul of towering buildings filled with Western establishments that will place herself back above the Japanese barbarians. Great things lie ahead for the Kingdom, great things. We must take action, your Majesty, without hesitation, to further modernize this still ancient kingdom."-Min Young-ik to Empress Myeongseong
