Overview

The universe has many secrets. It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now.

Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.

About the Author

Lisa Randall studies theoretical particle physics and cosmology at Harvard University, where she is Frank B. Baird, Jr., Professor of Science. A member of the National Academy of Sciences, the American Philosophical Society, and the American Academy of Arts and Sciences, she is the recipient of many awards and honorary degrees. Professor Randall was included in Time magazine's "100 Most Influential People" of 2007 and was among Esquire magazine's "75 Most Influential People of the 21st Century." Professor Randall's two books, Warped Passages (2005) and Knocking on Heaven's Door (2011) were New York Times bestsellers and 100 Notable Books. Her stand-alone e-book, Higgs Discovery: The Power of Empty Space, was published in 2012.

Chapter One

Entryway Passages: Demystifying Dimensions

You can go your own way. Go your own way. - Fleetwood Mac

"Ike, I'm not so sure about this story I'm writing. I'm considering adding more dimensions. What do you think of that idea?"

"Athena, your big brother knows very little about fixing stories. But odds are it won't hurt to add new dimensions. Do you plan to add new characters, or flesh out your current ones some more?"

"Neither; that's not what I meant. I plan to introduce new dimensions - as in new dimensions of space."

"You're kidding, right? You're going to write about alternative realities - like places where people have alternative spiritual experiences or where they go when they die, or when they have near-death experiences? I didn't think you went in for that sort of thing."

"Come on, Ike. You know I don't. I'm talking about different spatial dimensions - not different spiritual planes!"

"But how can different spatial dimensions change anything? Why would using paper with different dimensions - 11 X 8 instead of 12 X 9, for example - make any difference at all?"

"Stop teasing. That's not what I'm talking about either. I'm really planning to introduce new dimensions of space, just like the dimensions we see, but along entirely new directions."

"Dimensions we don't see? I thought three dimensions is all there are."

"Hang on, Ike. We'll soon see about that."

The word "dimension," like so many words that describe space or motion through it, has many interpretations - and by now I think I've heard them all. Because we see things in spatial pictures we tend to describe many concepts, including time and thought, in spatial terms. This means that many words that apply to space have multiple meanings. And when we employ such words for technical purposes, the alternative uses of the words can make their definitions sound confusing.

The phrase "extra dimensions" is especially baffling because even when we apply those words to space, that space is beyond our sensory experience. Things that are difficult to visualize are generally harder to describe. We're just not physiologically designed to process more than three dimensions of space. Light, gravity, and all our tools for making observations present a world that appears to contain only three dimensions of space.

Because we don't directly perceive extra dimensions - even if they exist - some people fear that trying to grasp them will make their head hurt. At least, that's what a BBC newscaster once said to me during an interview. However, it's not thinking about extra dimensions but trying to picture them that threatens to be unsettling. Trying to draw a higher-dimensional world inevitably leads to complications.

Thinking about extra dimensions is another thing altogether. We are perfectly capable of considering their existence. And when my colleagues and I use the words "dimensions," and "extra dimensions," we have precise ideas in mind. So before taking another step forward or exploring how new ideas fit into our picture of the universe - note the spatial phrases - I will explain the words "dimensions" and "extra dimensions" and what I will mean when I use them later on.

We'll soon see that when there are more than three dimensions, words (and equations) can be worth a thousand pictures.
