My apologies! I should not have assumed. There are communities of people who believe that there are indeed infinite universes where anything is possible and we can switch between them with our minds, so that is why I assumed what I assumed.
I did speak with someone else about the idea of a multiverse with infinite possibilities not too long ago, although with the idea that you could actually go to these places.
My response is the same as in the last part of my first message: If you can’t prove it or use it, then I don’t see a reason to bother with it too much. But it is still interesting theoretically.
Now, something popularized by TikTok is “Shifting”, which is the practice of actually going to these different universes. However, the experiences I’ve heard are exactly the same as astral projection. Whenever they die there, they simply return here, and often times pain isn’t experiences.
I think the idea of the multiverse is more appealing to people who have a general materialist world-view, in that they use it to suggest that all spiritual experiences are valid and not illusory, or it is actually a material experience than a spiritual one etc. As it’s simply an intermingling of different universes. Which, I am hesitant about personally. I think it’s something that can perhaps be reasoned on, however, which is important.
But some Ancient Greeks also believed in the idea of a multiverse. Interestingly, Plato seems to have disagreed with this, but his dialogue “Timaeus” will have to be read on the reasoning regarding that.
The Renaissance Magician and Astrologer Giordano Bruno, in a time when Europe still held onto an Aristotelian model of the cosmos, said that the Stars we see are actually Suns like ours, and they have their own Worlds like ours, and the Universe spans on infinitely, so the center of the Universe is essentially everywhere (At least, to my knowledge this is what he said).
So, the Universe could also be singular but infinite, rather than there being a Multiverse (Uni- does mean “One”, to represent all things together). We could also then say the physical laws here do not apply everywhere in the infinite Universe and are vastly different elsewhere. So, that essentially makes this singular Universe like the idea of the Multiverse with widely different laws.
Again, if it can’t be put into use or proven then I don’t see too much reason to bother with it, unless it can be reasoned on.
