Vortex to another dimension reported in Brighton. Vortex to another dimension reported in Brighton Updated 2:04pm Sunday 19th May 2013 in News By Anna Roberts, Crime reporter Vortex to another dimension reported in Brighton Council bosses have been left mystified after reports that a portal to another dimension has opened in a residential street in Brighton. A member of the public reported to Brighton and Hove City Council that the “wormhole or vortex” had opened up in Montreal Road, Hanover, on May 2. They made the report via the website Fix My Street which is more typically used to report potholes, dumped rubbish and broken lampposts.

The anonymous poster said: “I was recently walking my affenpinscher (a toy breed of dog) around the Hanover area of Brighton when I noticed that a wormhole or vortex has opened up on Montreal Road. “On closer inspection it seems to be some kind of portal to other times, places and dimensions. “I would have investigated further but I was concerned my little dog would be sucked into it. The Multiverse’s ‘Measure Problem’ | Quanta Magazine. 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 Stephen Hawking envision our universe as one of countless bubbles in an eternally frothing sea. This infinite “multiverse” would contain universes with constants tuned to any and all possible values, including some outliers, like ours, that have just the right properties to support life. The problem remains how to test the hypothesis.

Eternal Inflation. Multiverse & Universe Origins. Multiverse. Bubble Universe Schmubble Universe? | The Skeptics Guide to the Universe. Scientists are actually making progress scientifically determining whether we live in a bubble universe or not. The idea of separate bubble universes, of which ours is only one among innumerable others, has always been notoriously both non-verifiable and fascinating as hell. How can we possibly learn anything about another universe that, by definition, is nowhere to be found in our reality. Still, some theories seemed to allow for its existence and the images depicting them are so cool aren’t they?

The idea that all of reality is actually a multiverse consisting of bubble universes, is an outgrowth of Inflationary theory. The fact that this successful theory also allows for the concept of bubble universes immediately caught the public’s attention while at the same time being derided by scientists claiming that it was unscientific because it could not be tested. Bubbles are thought to have been created from whatever it was that existed before the big bang. Abstract. To Avoid the Multiverse, Physicists Propose a Symmetry of Scales. Though galaxies look larger than atoms and elephants appear to outweigh ants, some physicists have begun to suspect that size differences are illusory. Perhaps the fundamental description of the universe does not include the concepts of “mass” and “length,” implying that at its core, nature lacks a sense of scale. This little-explored idea, known as scale symmetry, constitutes a radical departure from long-standing assumptions about how elementary particles acquire their properties.

But it has recently emerged as a common theme of numerous talks and papers by respected particle physicists. With their field stuck at a nasty impasse, the researchers have returned to the master equations that describe the known particles and their interactions, and are asking: What happens when you erase the terms in the equations having to do with mass and length? Nature, at the deepest level, may not differentiate between scales. The new scale symmetry approach rewrites the beginning of that story.
