Mirror world of dark particles could explain cosmic anomaly". Physics World. 31 May 2022 . Retrieved 22 June 2022. If there were a large (possibly infinite) number of universes, each with possibly different physical laws (or different fundamental physical constants), then some of these universes (even if very few) would have the combination of laws and fundamental parameters that are suitable for the development of matter, astronomical structures, elemental diversity, stars, and planets that can exist long enough for life to emerge and evolve.

its highly unlikely that the universe is of finite size and probable that we’re simply bumping into hard limits of what’s measurable. so. universe.. way bigger than what we could ever see at light-speed!

When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.In May 2020, astrophysicist Ethan Siegel expressed criticism in a Forbes blog post that parallel universes would have to remain a science fiction dream for the time being, based on the scientific evidence available to us.

Nowadays, the world doesn’t seem so big anymore. You can reach point b from point a in a couple of minutes, hours, or in the worst case, days. Our perception is the only thing at play here. An early form of this reasoning is evident in Arthur Schopenhauer's 1844 work "Von der Nichtigkeit und dem Leiden des Lebens", where he argues that our world must be the worst of all possible worlds, because if it were significantly worse in any respect it could not continue to exist. [87] Occam's razor [ edit ] The Bayesian model focuses on how likely a model is to be correct, given the data, rather than asking how well the model itself fits the data. Now, this might not be the best method of estimating the true size of our Universe. Still, chances are very high that our Universe is nonetheless, bigger than the observable Universe. Does the Universe End? Jürgen Schmidhuber, however, says that the set of mathematical structures is not even well-defined and that it admits only universe representations describable by constructive mathematics—that is, computer programs.Cosmologist Max Tegmark has provided a taxonomy of universes beyond the familiar observable universe. The four levels of Tegmark's classification are arranged such that subsequent levels can be understood to encompass and expand upon previous levels. They are briefly described below. [62] [63] Level I: An extension of our universe [ edit ] There is a debate about whether the other worlds are real in the many-worlds interpretation (MWI) of quantum mechanics. In Quantum Darwinism one does not need to adopt a MWI in which all of the branches are equally real. [93] Modal realism [ edit ]
