Multiverse and Fictional Ideas

In summary: And if that's the case, then yes, fictional places in our minds would exist in other universes. But again, this is all theoretical. We have no way of knowing if it's actually the case or not. TL;DR Summary: Do fictional places that the human mind imagined exist in other universes? and if so, did that universe only exist after we came up with the idea or did we just happen to think about an already existing universe?

TL;DR Summary
Do fictional places that the human mind imagined exist in other universes? and if so, did that universe only exist after we came up with the idea or did we just happen to think about an already existing universe?
I'm a 16 year old who has wondered this question for a while. If the multiverse theory is correct, and I understand correctly, there would be infinite universes in which each universe would be different from another in some form. If this is the case, would that mean that places and worlds that we have created in our minds (places in movies, books, etc.) exist in other universes? And, if so, do the universes where these fictional places exist become real when we conceive it in our minds (and if that is correct, what power does consciousness hold in reality?), or, has that universe existed before, and we just so happen to think about it? Thanks.

No.

What multiverse theory? Please give a specific reference.

There isn't just one multiverse theory. And serious scientific ones limit "other worlds" to ones that form by some understood process. For example, the many worlds interpretation of quantum mechanics means that the "other worlds" have the same physical laws as this one, just different outcomes of measurements - i.e. different history. This is unlikely to manifest as "mirror universes" like in Star Trek because a sequence of events that makes everyone evil but otherwise unchanged is not really plausible.

So no, your imagination does not create alternate universes. You can easily imagine universes that don't even obey a systematic set of physical laws (indeed that covers almost all fiction), and that is clearly outside the realm of any physics.

Fictional universes generally violate the laws of physics in one way or another. Often in very mundane ways. Mythbusters has a bunch of episodes where they debunk various Hollywood tropes and shows that the real world doesn't work that way, for instance.

A simple example is gunfire. Gunfire is often shown to have a large "kick" to it, knocking people back. Turns out that in reality, the mass of the bullet is so small that it just doesn't impart much momentum to the target. Little stuff like that makes most fictional worlds impossible, even when the authors try really really hard to get everything right.

If our universe is truly infinite, then within the physical laws, then there could be entire areas that are exactly the same as ours but with one molecule of difference. "Could" be....
 

1. What is the Multiverse theory?

The Multiverse theory is a hypothetical concept in which there are multiple parallel universes that exist alongside our own universe. These universes may have different physical laws, constants, and even different versions of ourselves and everything around us.

2. Is the Multiverse theory supported by scientific evidence?

Currently, there is no direct evidence for the existence of a Multiverse. However, some theories in physics, such as string theory and inflation theory, suggest the possibility of a Multiverse. These theories are still being studied and researched, and more evidence is needed to confirm the existence of a Multiverse.

3. Can we travel to other universes in the Multiverse?

As of now, there is no known way to travel to other universes in the Multiverse. The laws of physics as we know them do not allow for such travel. However, some scientists are exploring the idea of using advanced technology, such as wormholes, to potentially access other universes.

4. Are fictional ideas, such as parallel universes and alternate timelines, possible in the Multiverse?

The concept of parallel universes and alternate timelines is a popular theme in science fiction, but it is also a possibility in the Multiverse theory. If there are infinite universes, then it is possible that there are versions of ourselves and our world that exist in different timelines or dimensions.

5. How does the Multiverse theory impact our understanding of the universe?

The Multiverse theory challenges our understanding of the universe and our place in it. It raises questions about the nature of reality and the possibility of other worlds and versions of ourselves. It also has implications for the search for extraterrestrial life and the origins of the universe.
