alexg said:No. All ideas about a multiverse are strictly hypothetical.
Rorkster2 said:Theories are in themsleves hypothetical. I'm quite aware that we only observe one universe, your missing my question.
Rorkster2 said:Darwins Theory of evolution was published in the 1800's, and he did not experiment before publishing his paper.
A theory is a set of ideas intended to explain something. Some theories have experiments that helped form them, not all. And if no was your answere then fine, but you said no...followed by a redundant statement that is of no help to my question which makes me believe your answer was directed to weather or not a multiverse is scientific fact, not about if their are theories about my question
ZapperZ said:This is patently false and shows that you've never read his book. The first 9 chapters of that book has nothing on a theory of evolution. Instead, it is all about his observations, i.e. DATA, the same as doing an experiment.
Theories in physics have to be stronger than hypothesis. It must either be derived at logically from First Principles, or is a phenomenological model based on existing empirical result.
I will once again urge attention to our Rules that everyone had agreed to, especially our policy on speculative posts.

Rorkster2 said:Stop splitting hairs with me please. I am asking a specific question and this has nothing to do with it.
I'm asking for a theory with a specific criteria, not a lesson on reading your forum rules. If you think that somehow I have crossed a line in asking about a multiverse in the category 'Beyond the standard model' then maybe it is you who needs to go back and read your policy.
Rorkster2 said:models that predict our universe to be a part of a multiverse in our own dimension?
bdavlin said:It would seem that this site could use some speculative posts. Zappers should remember that the understanding of physics was completely changed via the discoveries of the early 20th century. It is speculative thinking that paves the way of discovery in this field.

Interdimensional travel refers to the theoretical concept of traveling between different dimensions, which are alternate realities or parallel universes that may exist alongside our own. It is often depicted in science fiction as a way to explore different versions of reality or to access different levels of existence.
Scientists explore physical theories of interdimensional travel through mathematical models and theoretical physics. They use concepts such as string theory, quantum mechanics, and general relativity to try and understand the nature of different dimensions and how they may be connected.
Currently, there is no scientific evidence to support the existence of other dimensions or the possibility of traveling between them. However, some physicists believe that it may be theoretically possible through advanced technologies or by manipulating the fundamental laws of physics.
One potential consequence of interdimensional travel is the disruption of the fabric of space-time. As we currently understand it, traveling between dimensions would require bending or breaking the laws of physics, which could have unforeseen consequences. Another consequence could be encountering alternate versions of ourselves or alternate histories, which could have ethical implications.
Interdimensional travel is often linked to the concept of time travel, as traveling between dimensions could potentially involve traveling through different points in time. However, time travel specifically refers to the movement through time within our own dimension, while interdimensional travel involves moving between different dimensions. Both concepts are still theoretical and have not been proven to be possible.
