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.

Well what do you all think of the paradoxes that fill fiction from Terminator, Beastwars, Doctor Who, Back to the future, primeval and many others even Harry Potter. And other ones with names(that I know lol) like the grand father paradox.

even better how can we use paradoxes too generate worlds instead of alternate worlds they could be a messed up time lines like in my mutant mammal world where the world is based on Marvel/DC comics something like time travel stoped the Dinosaurs from evolving and their mesozoic Archosaur replacements from going extinct at the k-t event which caused all(Placental) Mammals to become mutants and the Archosaurs to become intellegent in response.

As long as the wormhole stayed opened, they would be two "independent" worlds. So, as long as the wormhole stayed open, the changes would not be enacted. Most of the fictional paradoxes are completely impossible. As long as a wormhole stayed open in your scenario, however, I don't think the changes could affect the present in any way.

The only known way to travel in time AT ALL in known physics is to use a wormhole.
You mean, besides singularities. Or, if you are certain particles you have retrocausality. Or, if somehow you can make a tube long enough to be infinite (or we have certain space-constants incorrect) a Tipler Cylinder. Even then, you could do it through the use of superluminal travel (it isn't always impossible, therr are some space-warp models that are technically possible that can lead to time travel).

Singularity: Which kind? The astronomical gravitational singularities, or one of the many types in physics? If you're talking about a gravitational one... hopw would we traverse this? A black hole???

Particles: Which ones? Sorry, my brain loaded with too much other stuff and I'm too damn lazy to try and remember nor try to research it.

Tipler Cylinder: In an ungodly amount of years, a Tipler Cylinder may be possible. But for now, and indeed, for a long damn time, it will be impossible.

Superluminal travel(Faster-than-light): Ummmmmm... no object in a localised area of space time can travel faster then the speed of light. Of course, someday it may be possible. I just don't know. At current however, I see one way of FTL speed. Under General Relativity, space has no definitwe limit on how fast it can expand. So... an engine that somehow makes space expand behind it? Again... mostly WTF ideas.

1. Gravitational Singularity or any kind kind. A black hole is the first one, just hang around in orbit outside the event horizon and you would experience time slower. This would help you travel forward in time. A naked singularity, while way harder to find, would be easier to use (no event horizon so you could go closer, there for, the effects could be greater) or depending on how a naked singularity behaves (pacifically how it influences light cones) you could even go back in time. I don't know about other G.Ses but I think you could use them as well.

2.Well,... I don't know and am way to lazy to do the research, too.

3. Same can be said for making or traveling to a wormhole. Or, even finding one.

4. I was talking about super-luminal travel through warping the space-time continuum. Which is just as possible as a wormhole as far as we know, in fact, space-warping is kind of needed for wormholes.

What about some sort of teleportation system based on the fact that particles can disapear and reapear any where(it's something like that any way).

Dinosaurs eat man, woman inherits the Earth.

I'm working on a time travel story, so I want to post my theory of time travel (BTW, time travel is COMPLETELY possible. We just haven't found out how to do it yet. They said light bulbs were impossible, but look what's over your head. They said space travel was impossible, but go to NASA's webste. Before you say "Time travel is different than light bulbs", I know it is. But just because it's different than light bulbs doesn't mean we can't make it).


Anyway my time travel theory (I'm going to be more ambiguous in the story):

We've long known and speculated that time and space intermingle. Sort of a space/time continuum. Well, I propose that the whole universe is just space and time.

I theorize that the universe is like a 2-D circle with many more 2-D circles stacked on top of it, making a 3-D cylinder. Each individual circle marks a very small measurement of time (smaller than a nanosecond). This is called a universal cylinder.

I also theorize that there are many more universal cylinders (parallel universes), each branching off of a central universe core. The cylinders that branch off of the core also have cylinders branching off of them, cylinders off of those cylinders, and so on. It's sort of like a tree. A universe tree.

Each universal cylinder branched off another universal cylinder because of some change, whether it is an extremely small change or an extremely large change.

Anyway, there is a theory that says that "Anything that can happen will." That's exactly what happend in this universal tree. Anything (and I mean ANYTHING) that could happen did in one universe or another. You can only travel inside your own universe cylinder. And you can only travel to universe circles that already exist.

Travel is done by wormholes. Not sure how they are created. Probably by quantum pores that I proposed in a previous thread (space travel).

Anyway, you can travel ONLY inside your home universe cylinder. So you can't go to a universe where the Nazis won WWII. Whatever you do during time travel, you won't affect your home universe cylinder; you'll just create a branching universe, if there isn't already one for what you did.

If you go back in time to kill your grandfather, you will kill him and you won't be born in a branching universe cylinder. But in your home universe cylinder, nothing would have happened. You'll remember what happened, but no one else will. To the time you traveled to, nothing would have happened.

This means that it would be impossible for you to go back in time to assassinate Hitler before he came into power.

Any questions or comments on how to make this theory better?

It seems sound, if impossible to know if there is a universal cylinder.

It's theoretical. We don't know ALL that exists out there and we probably never will.

Indeed. Your theory is fundamentally similar to my "Multiversal Bubbles" theorem.

There an nifinite amount of infitnite universal "bubbles" which each contain an infinite amoun of space time within a localised area of exstence. There is each a bubble for every single possible little difference in universes. Bubbles are constantly and infiitely expanding into an even more infinite complex of bubbles.

However, unlike your universal cylinder theory, the multiversal space, which is simply referred to as fluidic space, can be entered through use of a wormhole. All other universal bubbles have an actual "Universal location" but since they are infinitely replicating, no true location can ever be ascertained.

Interesting.

We'll probably never know how the whole multiverse is structured. So until we do, almost all theories are plausible.

The same goes for Time Travel, but that's what they said about landing on the Moon.
