The Multiverse: An Existential Crisis for Science?
Keywords:multiverse, Big Bang theory, eternal inflation, string theory (M-theory), anthropic “fine-tuning” of the universe, dark energy
This paper is a response to an article by American physicist andprofessor at the Massachusetts Institute of Technology (MIT) Alan Lightman, titled “The Accidental Universe.” Originally published in Harper’s Magazine, “The Accidental Universe,” is about the idea of a “multiverse” – a model of reality, in which our known “universe” is only a tiny, and insignificant member of an ensemble of many, perhaps an infinite number of universes. The explored topics in the paper include: the scientific theories that predict such a multiverse; the inherent obstacles to observing that multiverse in order to establish it as a scientific theory; the opposition from some scientists to the recognition of the multiverse as a valid theory; the implications of its possible acceptance as such for the scientific community, and the various philosophical questions, as well as fantastical possibilities that its existence could entail. Different possibilities and theoretical models are explored, and, finally, a perspective is offered for the near future in approaching the multiverse both from a scientific standpoint, and as humans in general.
