Brian Greene: Welcome to the Multiverse
The latest developments in cosmology point toward the possibility that our universe is merely one of billions. “What really interests me is whether God had any choice in creating the world.” That’s how Albert Einstein, in his characteristically poetic way, asked whether our universe is the only possible universe. The reference to God is easily […]
Neutrinos and multiverses: a new cosmology beckons
November 28, 2011
You wait decades for discoveries that could revolutionise physics, then three come along at once “THE universe is not only queerer than we suppose, but queerer than we can suppose,” as geneticist J. B. S. Haldane once remarked. In recent decades, physicists have done their best to prove Haldane wrong, by supposing some very queer […]
How to spot a multiverse
October 4, 2011
How can we tell if another universe has collided with our own? Physicists in Canada and the US believe they have the answer – it would leave “a unique and highly characteristic” imprint in the microwave background that pervades the cosmos. The physicists claim that the prediction can be tested using existing and future space […]
Time need not end in the multiverse
August 12, 2011
GAMBLERS already had enough to think about without factoring the end of time into their calculations. But a year after a group of cosmologists argued that they should, another team says time need not end after all. It all started with this thought experiment. In a back room in a Las Vegas casino, you are handed […]
This Week’s Hype
August 6, 2011
I noticed today that BBC News has a story headlined ‘Multiverse’ theory suggested by microwave background that assures us that: The idea that other universes – as well as our own – lie within “bubbles” of space and time has received a boost. After taking a look at the PRL and PRD papers that are behind this, it’s clear that a […]
First observational test of the ‘multiverse’
August 4, 2011
The theory that our universe is contained inside a bubble, and that multiple alternative universes exist inside their own bubbles – making up the ‘multiverse’ – is, for the first time, being tested by physicists. Two research papers published in Physical Review Letters and Physical Review D are the first to detail how to search for signatures of other […]
The multiverse and quantum physics: Other worlds may not be so far away
June 7, 2011
A new paper simplifies – slightly – our view of the cosmos by reconciling two theories relating to multiple universes , writes Roger Highfield. Let’s take two of the biggest, most bizarre and mind-blowing ideas in cosmology. First, the multiverse, the hypothetical set of possible universes that comprise all that exists. Second, the suggestion that […]
When the multiverse and many-worlds collide
June 1, 2011
ΤWO of the strangest ideas in modern physics – that the cosmos constantly splits into parallel universes in which every conceivable outcome of every event happens, and the notion that our universe is part of a larger multiverse – have been unified into a single theory. This solves a bizarre but fundamental problem in cosmology […]
Multiverse = Many Worlds
May 23, 2011
Two of the most bizarre ideas in modern physics are different sides of the same coin, say string theorists The many worlds interpretation of quantum mechanics is the idea that all possible alternate histories of the universe actually exist. At every point in time, the universe splits into a multitude of existences in which every […]
