Do you believe there are multiple dementions rather then just the one we see with our eyes everyday?

This is one of the many precepts of contemporary Quantum Theroy and 'M' Theory.

Probobility would suggest there are more that exist in more ways than we can comprehend.

There must be ... I'm seeing multiple identical threads! :eek:

lol

(emphasis added) Er... one dimension? Last time I checked space had at least three visible dimensions.

Yes, there are infinte numbers of universes, and at least 11 dimensions according to string "theory".

I'd heard 26. But as there is not yet any experimental evidence for string theory, the point is moot.

there probably are........I would think so anyway

There are at least three. Probably more. *nod*

According to Mario Bros. there are only two and no more. Except in stage three when you fall behind the block to get the whistle but that's an irregularity.

I'd like to believe there are more than 3.

There are many. How many, I don't know, and I don't believe anyone has actual proof of the number.

I believe there are infinite dimensions. If there is 1, 2, and 3 dimensions, why shouldn't there be more.

Plus time, right?

I think there are 11 under the "standard model", which has been repeatedly shown to be workable and useful. It was developed in 1973. However, there haven't been any more major breakthroughs since then and the field has grown ever more arcane and tangled...it might not even prove to be anything at all beyond the standard model, which brings us no closer to a unified theory.

YES! There is a world beneath this one, a world of auras and hyper reality with little bald doctors

Quit reading insomnia and get some sleep.

I think that it is possible for a spatial dimention to exist in addition to the X, Y, and Z axes. Much like Mario, our entire world is experienced within the constraints of a system that we cannot be completely aware of. If Mario could jump out of the screen and into the Z axis, either he wouldn't even be aware of this "new" dimention, or his head would explode. We might be living in a 5D universe, but unless we can perceive or interact with matter along the V(?) axis, it is irrelevant.

the Wave of Possibilities is endless. yes, definitely! probably infinite dimensions.

Here ya go. Funnily enough, Paul Harvey's one of the first guys to start talking about it!

*ahem*

Researchers at Northeastern University and the University of California, Irvine say that scientists might soon have evidence for extra dimensions and other exotic predictions of string theory. Early results from a neutrino detector at the South Pole, called AMANDA, show that ghostlike particles from space could serve as probes to a world beyond our familiar three dimensions, the research team says.

No more than a dozen high-energy neutrinos have been detected so far. However, the current detection rate and energy range indicate that AMANDA's larger successor, called IceCube, now under construction, could provide the first evidence for string theory and other theories that attempt to build upon our current understanding of the universe.

An article describing this work appears in the current issue of Physical Review Letters. The authors are: Luis Anchordoqui, associate research scientist in the Physics Department at Northeastern University; Haim Goldberg, professor in the Physics Department at Northeastern University; and Jonathan Feng, associate professor in the Department of Physics and Astronomy at University of California, Irvine.

The evidence, they say, would come from how neutrinos interact with other forms of matter on Earth.

“To find clues to support string theory and other bold, new theories, we need to study how matter interacts at extreme energies,” said Anchordoqui. “Human-made particle accelerators on Earth cannot yet generate these energies, but nature can in the form of the highest-energy neutrinos.”

In recent decades, new theories have developed – such as string theory, extra dimensions and supersymmetry – to bridge the gap between the two most successful theories of the 20th century, general relativity and quantum mechanics. Quantum mechanics describes three of the fundamental forces of nature: electromagnetism, strong forces (binding atomic nuclei) and weak forces (seen in radioactivity). It is, however, incompatible with Einstein's general relativity, the leading description of the fourth force, gravity. Scientists hope to find one unified theory to provide a quantum description of all four forces.

Clues to unification, scientists say, lie at extreme energies. On Earth, human-made particle accelerators have already produced energies at which electromagnetic forces and weak forces are indistinguishable. Scientists have ideas about how the next generation of accelerators will reveal that strong forces are indistinguishable from the weak and electromagnetic at yet higher energies. Yet to probe deeper to see gravity's connection to the other three forces, still higher energies are needed.

Anchordoqui and his colleagues say that extragalactic sources can serve as the ultimate cosmic accelerator, and that neutrinos from these sources smacking into protons can release energies in the realm where the first clues to string theory could be revealed.

Neutrinos are elementary particles similar to electrons, but they are far less massive, have neutral charge, and hardly interact with matter. They are among the most abundant particles in the universe; untold billions pass through our bodies every second. Most of the neutrinos reaching Earth are lower-energy particles from the sun.
AMANDA, funded by the National Science Foundation, attempts to detect neutrinos raining down from above but also coming "up" through the Earth. Neutrinos are so weakly interacting that some can pass through the entire Earth unscathed. The total number of "down" and "up" neutrinos is uncertain; however, barring exotic effects, the relative detection rates are well known.

AMANDA detectors are positioned deep in the Antarctic ice. The NSF-funded IceCube has a similar design, only it has about six times more detectors covering a volume of one cubic kilometer. A neutrino smashing into atoms in the ice will emit a brief, telltale blue light; and using the detectors, scientists can determine the direction where the neutrino came from and its energy.
The key to the work presented here is that the scientists are comparing “down” to “up” detections and looking for discrepancies in the detection rate, evidence of an exotic effect predicted by new theories.

“String theory and other possibilities can distort the relative numbers of ‘down’ and ‘up’ neutrinos,” said Jonathan Feng. “For example, extra dimensions may cause neutrinos to create microscopic black holes, which instantly evaporate and create spectacular showers of particles in the Earth's atmosphere and in the Antarctic ice cap. This increases the number of ‘down’ neutrinos detected. At the same time, the creation of black holes causes ‘up’ neutrinos to be caught in the Earth's crust, reducing the number of 'up' neutrinos. The relative ‘up’ and ‘down’ rates provide evidence for distortions in neutrino properties that are predicted by new theories.”

“The neutrinos accelerated in the cosmos to energies unattainable on Earth can detect the ‘footprint’ of new physics,” said Goldberg. “The ‘body’ responsible for the footprint can then emerge through complementary experiments at the new generation of human-made colliders. On all fronts, it is an exciting era in high-energy physics.”
