Instead, an attraction is seen when two parallel uncharged conductors are brought close together.  
If supersymmetry were unbroken, fermionic photinos would cancel the effect from photons, resulting in no net force.  Instead, an attraction is seen when two parallel uncharged conductors are brought close together.  First theorized by a Dutch physicist in 1948, for ten points, name this phenomenon arising from quantum vacuum fluctuations in the electromagnetic field.
