Electrons are fantastically round, say British scientists | Science After three months of experiments in a basement laboratory in London, scientists can confirm – with more confidence than ever – that the electron is very, very round. In the most exquisite measurements yet, researchers declared the particle to be a perfect sphere to within one billionth of a billionth of a billionth of a centimetre. Were the electron scaled up to the size of the solar system, any deviation from its roundness would be smaller than the width of a human hair, the team said. Abstruse as the experiment might seem, the work has profound implications for scientists wrestling with the mysteries of the cosmos. Even the slightest elongation of the electron can reveal what unknown particles might exist in nature, and even explain why matter won out over antimatter in the universe we observe.
Electron is surprisingly round, say scientists following 10 year study (PhysOrg.com) -- Scientists at Imperial College London have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere, in a study published in the journal Nature today. The experiment, which spanned more than a decade, suggests that the electron differs from being perfectly round by less than 0.000000000000000000000000001 cm. This means that if the electron was magnified to the size of the solar system, it would still appear spherical to within the width of a human hair. The physicists from Imperial's Centre for Cold Matter studied the electrons inside molecules called Ytterbium Fluoride.

There is only indirect evidence for the existence of supersymmetry, primarily in the form of evidence for gauge coupling unification. Supersymmetry is also motivated by solutions to several theoretical problems, for generally providing many desirable mathematical properties, and for ensuring sensible behavior at high energies.

At last the cautious BBC voices physicists’ majority view that Gravity is not explained by the “Standard Model” of physics (Pallab Ghosh 25 May 2011) – meaning ‘gravitons’ are unreal – in an offhand comment on the electron-is-round story. Modern physics is trying to get to grips with a finite size electron. Round-electron challenge to mainstream physics | Crisis-in-Physics
Graviton Theory The three other known forces of nature are mediated by elementary particles: electromagnetism by the photon, the strong interaction by the gluons, and the weak interaction by the W and Z bosons. The hypothesis is that the gravitational interaction is likewise mediated by an – as yet undiscovered – elementary particle, dubbed the graviton.
Gravity, Branes And Hidden Dimensions
THEORIES OF THE BRANE The high concentration of the graviton near the brane—let's call the brane where gravity is localized the Planck brane—leads to a natural solution to the hierarchy problem in a universe with two branes.
Other dimension gravitons as the dark matter source The Question (Submitted July 26, 2006) Since string theory implies up to 11 dimensions, could dark matter be gravitons leaking from other dimensions into ours?

A brane, in string theory and related theories such as supergravity theories, is a physical object that generalizes the notion of a point particle to higher dimensions. For example, a point particle can be viewed as a brane of dimension zero, while a string can be viewed as a brane of dimension one. It is also possible to consider higher dimensional branes. In dimension p, these are called p-branes. Membrane (M-theory)
