Why the multiverse is religion, not science.

Описание: In this video I explain why the multiverse hypothesis is logically equivalent to the hypothesis that god exists, and therefore is not scientific.

I also address the common objections that physicists raise to this.

First, they will claim that I am saying the multiverse does not exist. But this is not so. I am saying that making statements about the existence of that part of the multiverse which is not our own universe is not scientific.

Second, they will claim that the multiverse is a simple explanation. This is just wrong. Postulating the existence of the multiverse does not explain anything. The simplest assumption is none, ie not say anything about whether the multiverse exists.

Third, they will argue that the existence of the multiverse it is a prediction of their theories. That is also wrong. Theories do not predict whether something exists or not. We deduce that something exists if it is useful to describe observations. This is not the case for the multiverse.

Fouth, they'll argue that then I should also not talk about the inside of black holes. In my video I explain why black holes are a different case.

Fifth, they will claim that some multiverse ideas make testable predictions. This is right. These ideas are unscientific for a different reason that we will talk about in more detail some other time. In brief, falsifiability is not enough to make a hypothesis scientific.
