Parallel worlds

[stardust]

Can there be another world like this one, with everything same as this one or maybe a bit different?

. . . if particular conditions of some varieties of theoretical physics are true in fact and not just misleading theories, then yes, although I not really knowledgeable enough about that branch of science to give a thorough explanation.

In general, there are many ways in which there could be a multiverse, most of them related to solving mysteries about the origins of this universe or the apparently indeterminate motions of microscopic particles.

In theory. I think Einstein believed in the theory. Basically since the beginning of time (if it ever had a starting point), every moment of existance from the original would spawn new universes where anything happened differently. eg In this world man a kills man b, but before he does, universes are spawned with alternate end results such as weapon breaks, man b has gun, man a changes mind, etc.
Ultimately, like a domino effect, you have worlds not just similar to this one, but worlds that are vastly different, and of course, worlds that have no perceivable difference.
An interesting question is this: If the laws of physics are the same across the board, will parallel universes only begin to be spawned when organic organisms/ creatures of free will eventuate?

Einstein didn't live in a time where it was scientifically acceptable to suspect a multiverse and his work didn't revolve around the possibility. I doubt he even gave the subject much thought, and if it did he probably would have found it an awkward addition to his Spinozist mindset.

In fact, it is still not agreed upon that contemporary times are a scientifically acceptable time to suspect a multiverse.

I think morality games is correct when he says the multiverse is a theory more about "the apparently indeterminate motions of microscopic particles." rather than the spawning of new universes.

Einstein would be correct if we took inverses into account.

Everything effects its environment. When a rock lands on soft clay it leaves an impression. The clay now is a model of that rock. Not a perfect one by any means but it's still a model.

The rock also is now a model of the clay. Note, to create that model, the clay had to give quite a bit more than the rock did.

When predators and their prey evolve to be faster and faster, they're modeling each other.

By studying the predator you can learn about the prey and visa-versa.

Just as there are two different types of matter, there are (at least) two different realities. One consists of the things that have happened. The other consists of things that could have happened.

In this system, things that didn't happen were destined to not happen and therefore should not happen. (Yes admitedly a tautology)

Also, things that happen are absolutely meant to happen... since they happened. (Yes admitedly a tautology)

So in essence, our existence is an indirect model of what should not happen.

It's either a huge inverse-universe or a very crowded group of multiverses. Either way, it's there.

I think that from the begining of time the different stuff in this universe has been smashing into each other and the whole time creating better and better models of their environments. I think this is what has led to us. I think the multiverse is made up of the minds of the entire human population.

Just you asking this question caused at least a few more to spring into existence :)
