Tautological Many Worlds?

this is my first question here so I hope I'm following the guidelines correctly. I recently found a relatively obscure physicist/philosopher who asserts that the concept of Many Worlds is ...

If Something Exists Does Everything Exist?

Has anyone argued this? I haven't formulated a coherent argument so I'm just throwing this out there to see if anyone has thought about this already. Intuitively I think it makes sense that everything ...

What is the response to this criticism of the fine-tuning argument?

So the fine tuning argument has been used to argue for theism, or the multiverse. The argument as I understand it goes something like this: We live in a universe with life. The physical constants of ...

Is Neil Barton's algebraic/ontological distinction equivalent to the actualist/possibilist distinction?

In, "Multiversism and Concepts of Set: How much relativism is acceptable?" Neil Barton distinguishes between an ontological interpretation of set-theoretic multiverses as referents and an ...

Could everything exist? What would this even mean?

I saw something that said the reason the universe exists is that everything exists, in an infinite multiverse. This then answers why the laws of physics of our universe are the way they are, which is ...

Being a determinist and a believer in a multiverse seems contradictory

A determinist holds that everything is determined by the physical world around them and free will is an illusion. A multiverse suggests there are an infinite number of alternative universes in ...

Do multiverse theories undermine intelligent design arguments mathematically?

It is well known that the probability of life arising in a universe of our sort is vanishingly small. Theists have used this fact to argue that life is designed by God. However, if there are an ...

Does free will contradict the theory of infinite universes

Let's imagine that we live in a world with infinite universes. One of these universes is the same as the one we live in, except for one change: this morning I choose to cut off my leg for some reason, ...

The supposed "knockdown argument" for Simulation Theory -- what did I miss? (IF we can create simulations indistinguishable from reality...)

I have never read any extensive formulation of the argument; I've only listened to people (like Elon) lay it out in Youtube videos; so I don't know what it's called or how to lay it out with rigour; ...

Does Tegmark himself include paraconsistent mathematical structures in his mathematical multiverse hypothesis?

Tegmark postulates in his hypothesis that all possible mathematical structures would exist. But does he include also possible mathematical structures described by other types of logic like ...

Forcing and justification

In "The set-theoretic multiverse," Hamkins talks about forcing giving us "glimpses" of other set-theoretic universes. He states his position as a Platonistic one, i.e. these "...

"Where" does the counterpart relation subsist?

AFAIK, according to the counterpart theory, it is true of me that I could have lived a different life, if my counterpart in another possible world did live a different life. But where is it true that ...

Does the forcing phenomenon prove some sort of set-theoretic multiverse?

It seems that, "A can be forced to equal B," allows, "A is possibly equal to B." In possible-worlds lingo, this gets us, "There is a possible world where A = B." Since ...

Does an Eternal Multiverse Undermine Causality, Time and Free Will? [closed]

An eternal multiverse is a static multiverse that just exists and is presented as a series of static moments, and each moment is separated by proper time (in the relativistic sense) and has many ways ...

Why are some things considered "impossible" even in other universes?

For example, I often hear that life could not develop in a universe where the fundamental constants were even slightly changed, or where certain physical laws were different. But if we're dealing with ...

Is the science community reluctant to consider the evidence to support some sort of higher intelligence? [closed]

Scientists can explain how life has developed to the stage we are at today, but they can’t explain why the process of evolution exists or what the spark was that brought life about at all. We are ...
