That is very true. Yet I still find it very hard to think about multiple universes. How could we know they exist if those universes that exist are separate from each other and don't interact. The maths might check out, the predictions within our universe might check out... but it seems to me like we don't have a way of ruling out alternative explanations that don't require more universes, unless we observe those other universes or their effects... but (as far as I know) we can't do that (yet)

Our universe started on Wednesday and the forecast clash with Andromeda is tomorrow on Saturday :)

I took this argument a step further in my book, The World Within back in 2018. I argue that the universe is not in fact expanding, but rather feeling the effects of subduction / divergence from other universes either sliding above / underneath ours / crashing into ours, basically overlapping or making contact at the boundary zones. My argument also suggests that all universes are on a sphere, thus giving the impression of expansion in the same way people used to think that the earth’s crust was expanding, when in fact material was just subsiding underneath other continental crusts and thus giving the appearance of expansion. We talk about the corners of our Universe, but in my theory, there are no corners - everything is operating on a sphere, which supports how it can both be flat and curved at the same time. The result of the spherical concept is that, like the separation and reassembly of continental continents every so many million years, I propose that universes act in a similar way.

It's a great pleasure to see how a simple question, which I always had, can be explained from a point of view which is logic to me. What was there before. Is it a continuum or is it something static.. I believe in the continuum. Because we are, as humans, used to think in beginning and ending of every aspect in our life. But in fact there is no beginning and no end. Everything was there before. I knew that as a child and are still convinced that it is true. It's the most reasonable way. We also will discover, some time, that it really doesn't matter if there is a universe. The universe is there. Nothing more or less. It's just there in one way or another. Maybe we will find out how and but never why. The "Why" question about the existence of the universe is in my opinion the most stupid question you ever could ask. It's just there. The universe isn't interested what we think of it. We think that we are very important but in fact we are just a glimp. Not more than some atoms and quarks. That's all there is.

YES! This is what I have believed for some time. Many worlds also explains why our universe appears so tuned for life without having to invent infinity other universes, because it still allows for our universe and all other versions to have the same starting point at the big bang. The universe is like one huge quantum computer playing out all possible configurations at the same time where the unviable ones end while the stable ones continue forward for as long as they can remain stable. It begs the question as to the purpose of the computation. Does all computation and energy ultimately continue through to the longest surviving universe before reaching a final state, or is there some other purpose? Something must be right in our universe to have continued on for 13.5 billion years, so what is it? Is our version of the constants leading to a preferred outcome, or are we still in the earliest fraction of a moment since the big bang and stuck with accelerating expansion that eventually make our universe unviable while others with steady state expansion continue onward?

this makes sense . cause and effect is linear and robotic with no room for anything else than reacting to what happened directly before, but memory and experience isn't, so it means that something happening now can be affected by something that happened way back in the past, even though at the time they were causally disconnected. so, as neo in the matrix said, "the problem is choice". we are trying to understand how the multiverse can exist when we only see evidence of the one we're living in, while also apparently having free will to make decisions that let us move into any multiverse we want, one choice at a time. isn't our ability to chose in itself proof that we live in a multiverse? If we couldn't make any decisions and felt like nothing we do could change the course of our experience, then that would suggest we're stuck in a single universe with no other possible outcomes.

If you imagine a dark empty space with nothing at all in it, no energy, no matter or atoms, nothing, you are still picturing a dark empty place which is of course, still something. You may even subconsciously picture yourself in that space because you know there has to be a you there to see through your eyes, someone to observe it and so again, it's not empty. When space expands, it just creates more space but that space isn't moving into or growing into anything, it's just making more space. We will only ever be able to see so far back into the universe but never beyond and so to ask such a questions seems rather pointless.

Funny that the starting question is a fundamental human question. The notion to ask „what was before spacetime“ is silly since there is no „before“ without space time. There’s also no dark energy btw… it’s a lack of informational content. Physics don’t mix well with the actual nature of the reality we are observing. The human interpretation of entropy is solely subjective and resembles no deeper insight whatsoever.

The Multiverse is a way of avoiding the infinity of a single Universe. But how can a Multiverse be smaller and have a more comprehensive point than a single Universe ? Because there is ( an unknown ) Darwinian pressure and some Universes that loop backwards. A Multiverse can be finite and if not finite ? the model can be undefined ( in numbers ) which is separate from being knowingly infinite. Popular models that are infinite include "The Cyclical Universe" and "The Steady State Universe". Because infinity leads to garbage predictions and garbage math, these models are junk. And that's putting it nicely. The outcomes of dark energy in this presentation are a speculation. What's more interesting is how dark energy and gravity coexist and how the ratio can affect the birth of a new Universe or new phenomena within or outside our current Universe, that is, if the Multiverse is the correct model. ( this includes awareness in some models ) Lastly. Everything about QM suggests that the Multiverse is the only viable model.
