Dimensions and Multiverse

Understanding A 10 Dimensional Universe. When someone mentions “different dimensions,” we tend to think of things like parallel universes — alternate realities that exist parallel to our own, but where things work or happened differently.

Understanding A 10 Dimensional Universe

However, the reality of dimensions and how they play a role in the ordering of our Universe is really quite different from this popular characterization. To break it down, dimensions are simply the different facets of what we perceive to be reality. We are immediately aware of the three dimensions that surround us on a daily basis – those that define the length, width, and depth of all objects in our universes (the x, y, and z axes, respectively).

Beyond these three visible dimensions, scientists believe that there may be many more. Parallel Universes: Theories & Evidence. Is our universe unique?

Parallel Universes: Theories & Evidence

From science fiction to science fact, there is a proposal out there that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. So, instead of turning down that job offer that took you from the United States to China, the alternate universe would show the outcome if you decided to venture to Asia instead. The idea is pervasive in comic books and movies. For example, in the 2009 "Star Trek" reboot, the premise is that the Kirk and Spock portrayed by Chris Pine and Zachary Quinto are in an alternate timeline apart from the William Shatner and Leonard Nimoy versions of the characters. The concept is known as a "parallel universe," and is a facet of the astronomical theory of the multiverse. Around 13.7 billion years ago, simply speaking, everything we know of in the cosmos was an infinitesimal singularity.

One big question with this theory is: are we the only universe out there. 1. Understanding A 10 Dimensional Universe. Cosmic Confusion: Talk of Multiverses and Big Errors in Astrophysics. "I would like to talk about a very serious embarrassment," said Mario Livio, a proclaimed scientist and author, at a panel at the World Science Festival in New York City last month.

Cosmic Confusion: Talk of Multiverses and Big Errors in Astrophysics

With three other prominent astrophysicists on the panel, Livio delved into one of the most confounding (and embarrassing) problems in modern astrophysics, which led to a discussion of whether or not our universe might be just one of an infinite number of multiverses— and whether a theory of the multiverse is good or bad for science. The embarrassment Livio referred to is sometimes known as the vacuum catastrophe. Truly empty space, sucked dry of any air or particles, still has an inherent energy to it, according to observations, Livio said. But when scientists use theories of quantum mechanics to try and calculate this vacuum energy, their results differ from the measured results by about 120 orders of magnitude, or the number 1 followed by 120 zeros.

Brian Greene: Making Sense of String Theory & the Hidden Universe

If, by some miraculous chance, you’ve never heard of it before, well, prepare to be introduced to one of the most interesting and highly contested ideas in physics. String Theory, in its most basic sense, asserts that, if we could zoom in and see the smallest building blocks of matter—if we soared past the atom and protons and quarks, and we got all the way down to the smallest of the small—we would find strings. This is the fundamental idea of superstring theory (“string theory” for short). It claims that the electrons and quarks that make up all the matter in our universe are not zero-dimensional objects, but one-dimensional strings. But what supports this idea? Well, to begin with, we don’t know that strings exist; however, there are a lot of scientists who think that they might. You see, beneath this somewhat poetic overview of string theory lies (what is arguably) the most advanced mathematics in the world.

What It’s Like to Live in a Universe of Ten Dimensions

What would happen if you crossed the physics of time with the science of something and nothing? You might get closer to understanding the multiverse. In Imagining the Tenth Dimension: A New Way of Thinking About Time and Space, Rob Bryanton — a self-described “non-scientist with an inquisitive mind,” whose dayjob as a sound designer involves composing music for TV series and films — proposes a theory of the universe based on ten dimensions, a bold and progressive lens on string theory based on the idea that countless tiny “superstrings” are vibrating in a tenth dimension. For a taste, here is a mind-bending explanation of ten dimensions might mean: The project began as a set of 26 songs, exploring the intersection of science and philosophy.

Before launching into the additional dimensions, Bryanton also breaks down the familiar three: HT It’s Okay To Be Smart Donating = Loving Brain Pickings has a free weekly newsletter.
