Considering the multiple universe view, if a measurement (or something else) makes visible which universe we are in, is it then also possible we find ourselves in one with (slightly) different laws of nature?
Not sure what you mean. We are in the universe we are in. There is zero evidence of the existence of other universes (the "multiverse") but if such do exist it is believed that there can be no causal connection between our universe and any other.entropy1 said:Considering the multiple universe view, if a measurement (or something else) makes visible which universe we are in, is it then also possible we find ourselves in one with (slightly) different laws of nature?
Maybe I am using the wrong terminology, and do I have to say: "Many worlds". I was inspired by this:phinds said:Not sure what you mean. We are in the universe we are in.

I don't know much at all about this. I have heard though things along the line as that 'quantum uncertainty' (what is that?) allows for virtually an infinite amount of universes. So I was thinking: could there be universes among them that are looking slightly or even entirely different with respect to laws of nature, and would these 'quantum uncertainties' allow for navigating towards these universes? I guess a different way to phrase this would be: 'do the laws of nature have to be fixed?'. May be far fetched, but I am incredibly curious!andrewkirk said:When a measurement is made, we are not branching to create a new world, we are doing a test to find out which world we are in.
I take no position in this. I am interested in the way QT sets boundaries on different approaches of conceptualising the phenomena in QM (preferably in a subjectivistic mathematical way).phinds said:I think the many worlds interpretations of QM are utter blather so I'm not the person to help you with this.

Multiple universes, also known as the multiverse theory, is the idea that there are an infinite number of parallel universes existing alongside our own. These universes may have different physical laws, dimensions, and timelines, and may or may not contain versions of ourselves or alternate realities.
Currently, there is no way to directly measure or observe other universes. The concept of multiple universes is mainly theoretical and based on mathematical models and theories such as quantum mechanics and string theory. Some scientists are also exploring the possibility of using advanced technologies, such as particle accelerators, to indirectly gather evidence for the existence of other universes.
The laws of nature are considered to be constants in our universe and are used to explain and predict the behavior of matter and energy. In the multiverse theory, it is believed that these laws may vary in each universe, allowing for different physical properties and outcomes. This concept is still highly debated and has not yet been proven.
Some theories suggest that the existence of other universes may have an impact on our own, such as the possibility of alternate versions of ourselves in different universes or the idea that our universe may have been created by the collision of two or more universes. However, these implications are still largely hypothetical and have not been scientifically proven.
In some interpretations of the multiverse theory, time is seen as a dimension that can exist in different directions or even have multiple branches. This means that there could be versions of ourselves in other universes living in different time periods or experiencing different outcomes. However, the concept of time in relation to multiple universes is still a topic of debate and further research is needed to fully understand its role.
