Brian Greene on The Hidden Reality
Sometimes it's applied to separate realms, ones that are partly or fully, temporarily or permanently, inaccessible to us; in this sense, the word relegates ours to membership in a large, perhaps infinitely large, collection. With its hegemony diminished, "universe" has given way to other terms introduced to capture the wider canvas on which the totality of reality may be painted. Parallel worlds or parallel universes or multiple universes or alternate universes or the metaverse, megaverse, or multiverse — they're all synonymous and they're all among the words used to embrace not just our universe but a spectrum of others that may be out there.
You'll notice that the terms are somewhat vague. What exactly constitutes a world or a universe?
A Physicist Explains Why Parallel Universes May Exist
What criteria distinguish realms that are distinct parts of a single universe from those classified as universes of their own? Perhaps someday our understanding of multiple universes will mature sufficiently for us to have precise answers to these questions. For now, we'll use the approach famously applied by Justice Potter Stewart in attempting to define pornography.
While the U. Supreme Court wrestled mightily to delineate a standard, Stewart declared simply and forthrightly, "I know it when I see it.
What matters, what's at the heart of the subject, is whether there exist realms that challenge convention by suggesting that what we've long thought to be the universe is only one component of a far grander, perhaps far stranger, and mostly hidden reality.
During the last half century, science has provided ample ways in which this possibility might be realized. Varieties of Parallel Universes 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.
Some of the earliest scientific forays into parallel worlds were initiated in the s by researchers puzzling over aspects of quantum mechanics, a theory developed to explain phenomena taking place in the microscopic realm of atoms and subatomic particles. Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.
We can predict the odds of attaining one outcome, we can predict the odds of another, but we generally can't predict which will actually happen.
This well-known departure from hundreds of years of scientific thought is surprising enough. But there's a more confounding aspect of quantum theory that receives less attention. How many times have you encountered upon a book whose subtitle or blurb claims that everything you know about something — success, economics, the world — is altogether wrong?
Chances are: too many to remember them all! In other words: prepare to be shaken to your very core! And Why?
You may be one of the many people believing that physics is not about everybody and that only those who understand equations should dabble with it. Be warned, though: If you have come here without at least some average understanding of physics, then your whole worldview is about to be radically altered.
Bear in mind that very few things in this book are scientific speculations and, obviously, they all come with an appropriate footnote. Most of it is cutting-edge science. Ever since , he has been a professor at Columbia University. As you can see from the full playlist, Greene discusses a few more things: You may know Sir Isaac Newton as the guy who robbed God of his job when he rendered all motion comprehensible and predictable through his laws of motion.
Among the many other, he also initiated the great debate on the nature of space and time. Both parties traded blows, but then, in Newton delivered the most damaging one: the water bucket argument. The argument is relatively simple: take a bucket filled with water and hung it by a cord. Then twist the cord tightly on itself and release.

The bucket should start spinning rapidly. Now, even though the relative motion at the first stage is the greatest, the surface of the water will remain flat. After a while, however, as the water starts to spin in the bucket, its surface will become concave.But these youthful flights of fancy, with their imagined parallel realities, resonate with an increasingly prominent theme in modern science — the possibility of worlds lying beyond the one we know.
And it will remain so even when the bucket is stopped. And if they did, if our universe got hit by another, had a fender-bender with another universe, that would send ripples going through the cosmic microwave background radiation - heat left over from the Big Bang.
Do you think we will one day achieve such proof, one way or another?
The Hidden Reality
Strangely enough — it is not. That would mean that you may be doing something else.
Such theories can yield predictions testable through experiments we undertake here, in this single universe of ours. This well-known departure from hundreds of years of scientific thought is surprising enough.
