Excerpt from Brian Greene the Hidden Reality and response

"A striking fact (it's in part what propelled me to write this book) is that many of the major developments in fundamental theoretical physics — relativistic physics, quantum physics, cosmological physics, unified physics, computational physics — have led us to consider one or another variety of parallel universe. Indeed, the chapters that follow trace a narrative arc through nine variations on the multiverse theme. Each envisions our universe as part of an unexpectedly larger whole, but the complexion of that whole and the nature of the member universes differ sharply among them. In some, the parallel universes are separated from us by enormous stretches of space or time; in others, they're hovering millimeters away; in others still, the very notion of their location proves parochial, devoid of meaning. A similar range of possibility is manifest in the laws governing the parallel universes. In some, the laws are the same as in ours; in others, they appear different but have shared a heritage; in others still, the laws are of a form and structure unlike anything we've ever encountered. It's at once humbling and stirring to imagine just how expansive reality may be."

- I feel like the topic of parallel universes and alternate similar dimensions is really complex. I think its amazing that there could be another existence where mostly everything is the same as it is here with minor or major changes. I watched a video on YouTube that spoke about how there are 10 "known" dimensions that dictate the universe and one statement made was that we cant view any of the higher dimensions but that they you and me may exist there under a different set of constants and standards.
