    THE curtain at the edge of the universe may be rippling, hinting that there's more backstage. Data from the European Space Agency's Planck telescope could be giving us our first glimpse of another universe, with different physics, bumping up against our own. That's the tentative conclusion of an analysis by Ranga-Ram Chary, a researcher at Planck's US data centre in California. Armed with Planck's painstaking map of the cosmic microwave background (CMB) - light lingering from the hot, soupy state of the early universe – Chary revealed an eerie glow that could be due to matter from a neighbouring universe...

    Imagine if you were told that the world is simple and exactly as it seems, but that there is an infinite number of worlds just like ours. They share the same space and time, and interact with each other. These worlds behave as Newton first envisioned, except that the slightest interactions of the infinite number create nuances and deviations from the Newtonian mechanics. What could be deterministic is swayed by many worlds to become the unpredictable. Schrdinger, in explaining his wave function and the interaction of two particles (EPR paradox) coined the term entanglement. In effect, the MIW theory is...

    If modern physics is to be believed, we shouldnt be here. The meager dose of energy infusing empty space, which at higher levels would rip the cosmos apart, is a trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion times tinier than theory predicts. And the minuscule mass of the Higgs boson, whose relative smallness allows big structures such as galaxies and humans to form, falls roughly 100 quadrillion times short of expectations. Dialing up either of these constants even a little would render the universe unlivable. To account for our incredible luck, leading cosmologists like Alan Guth and...

    Scientists are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never mind the Big Bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate -- bubbles formed.

    Last week, in Nice, France, I was privileged to participate along with 30 scholars, mostly scientists and mathematicians, in a conference on the question of whether the universe was designed, or at least fine-tuned, to make life, especially intelligent life. Participants — from Yale, Princeton, Harvard, Berkeley, and Columbia, among other American and European universities — included believers in God, agonistics, and atheists. It was clear that the scientific consensus was that, at the very least, the universe is exquisitely fine-tuned to allow for the possibility of life. It appears that we live in a “Goldilocks universe,” in which both...

    The spectacular discovery of the Higgs boson in July 2012 confirmed a nearly 50-year-old theory of how elementary particles acquire mass, which enables them to form big structures such as galaxies and humans. The fact that it was seen more or less where we expected to find it is a triumph for experiment, its a triumph for theory, and its an indication that physics works, Arkani-Hamed told the crowd. However, in order for the Higgs boson to make sense with the mass (or equivalent energy) it was determined to have, the LHC needed to find a swarm of other particles,...

    Hiding from God in the Multiverse by Jake Hebert, Ph.D. * ICR research sometimes involves detecting flawed logic in common evolutionary arguments. One such argument claims that something called the multiverse removes the need for a Creator. Is this claim valid? In an attempt to solve serious problems in the original Big Bang model, secular cosmologists invoked something called inflationan enormous hypothetical growth spurt in the early universe. Originally, these theorists believed that inflation would have completely ended shortly after the Big Bang. However, they later concluded that different regions of space stopped inflating at different times. This would result...

    Scientists believe they have found the first evidence of the existence of other universes beyond our own, following analysis of the radiation left behind by the Big Bang. Data gathered by the European Space Agency's Planck spacecraft enabled researchers to map the "cosmic microwave" of background radiation left behind when the universe began 13.8 billion years ago. The findings imply the universe could be just one of billions, or even an infinite number, they say. The map showed anomalies that cosmologists believe could only have been caused by the gravitational pull of other universes outside our own. "These anomalies were...

It seems like science fiction and it has certainly been a staple of science fiction for at least forty years. It may have remained science fiction but fortunately I am not alone in believing this might in fact be possible.

    Victor Stenger, a retired physics prof from the University of Hawaii, has given us two books that explain both atheism and "multiverses", and behold, they are one. Few other proponents of multiverses are quite as forthcoming with their logic, but clearly something besides data must motivate the science of multiverses, because by definition multiverses are not observable. Stenger makes the connection explicit, whereas Hawking or Susskind is a little more coy with their metaphysics. Multiverse-theory is designed for one purpose, and one purpose only, and that is to defend atheism. It makes no predictions, it gives no insight, it provides...

    You have probably heard about the multiverse--the idea that the universe is really a large number of universes. The multiverse helps to explain why our particular universe seems so special. Our universe seems to be a finely tuned machine and the evolution of life would require low probability events. Is our universe special? The multiverse helps to deflect such thinking. If there is a large number of universes, then perhaps each has a different set of natural laws. And perhaps intelligent life can only be supported by a very particular set of laws. So the only life forms that would...

One obvious question that arises, then, is exactly how many of these parallel universes might there be. In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated...
