    universe today ^ | 04/26/2017 | Matt Williams
    Known as the “CMB Cold Spot”, scientists have puzzled over this anomaly for years... ... Multiverse Theory, which was first proposed by philosopher and psychologist William James, states that there may be multiple or an even infinite number of Universes that exist parallel to our own. Between these Universes exists the entirety of existence and all cosmological phenomena – i.e. space, time, matter, energy, and all of the physical laws that bind them. [T]he theory arose in part from the study of cosmological forces, like black holes and problems arising from the Big Bang Theory. In addition, variations on multiverse...

    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...

    The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics. But the idea that we live in a 'multiverse' made up of an infinite number of parallel universes has long been considered a scientific possibility - although it is still a matter of vigorous debate among physicists. The race is now on to find a way to test the theory, including searching the sky for signs of collisions with other universes.

    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. Schrödinger, in explaining his wave function and the interaction of two particles (EPR paradox) coined the term “entanglement”. In effect, the MIW theory is...

    Quanta Magazine ^ | 11/3/14 | Natalie Wolchover and Peter Byrne
    If modern physics is to be believed, we shouldn’t 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, it’s a triumph for theory, and it’s 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 “inflation”—an 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...

    I have long been fascinated by the idea that the universe is not actually a singular object but made up of a multiverse of infinite universes. Each of these Universes is seemingly branch off at every possible action or inaction. This idea is staggering in it’s immensity. 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.

    My endless rants here about the hot field of multiverse studies are mainly motivated by concern about the effect this is having on particle theory. Multiverse scenarios all too often function as an excuse for not admitting that string theory/extra-dimensional ideas about unification have failed. Such an admission would encourage people to move on to more promising ideas, but instead hep-th is stuck in an endless doldrums with the high profile public face of the subject dominated by excited claims about what a wonderful discovery this region is.Independently of the string theory problem, I’m personally a skeptic that multiverse...

    Big as it is, our universe may be just one of many, all floating in a nearly unfathomable "multiverse," scientists say. Problem is, there's been no way to test the idea. Now, though, physicists say they've devised a way to detect "bruises" from our cosmos's purported collisions with other universes. The international team has created a new computer algorithm to hunt for such irregularities in our universe, which they say would be disk-shaped—think of the temporary, circular flattening that happens when one beach ball bumps into another. Because the multiverse would likely have expanded so fast that its universes would...

    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 a fair coin to flip. You will not be allowed to see the outcome, and the moment the coin lands you will fall into a deep sleep. If the coin lands heads up, the dealer will wake you 1 minute later; tails, in 1...

    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...

    Modern cosmology theory holds that our universe may be just one in a vast collection of universes known as the multiverse. MIT physicist Alan Guth has suggested that new universes (known as “pocket universes”) are constantly being created, but they cannot be seen from our universe. In this view, “nature gets a lot of tries — the universe is an experiment that’s repeated over and over again, each time with slightly different physical laws, or even vastly different physical laws,” says Jaffe. Some of these universes would collapse instants after forming; in others, the forces between particles would be so...
