The author's assertions concerning the conditions that lead to the decay of the vacuum would be most weakened if which of the following occurred? A. Scientists created an electric field next to a vacuum, but found that the electric field was not intense enough to create a charged vacuum. B. Scientists assembled a superheavy atomic nucleus next to a vacuum, but found that no virtual particles were created in the vacuum's region of space. C. Scientists assembled a superheavy atomic nucleus next to a vacuum, but found that they could not then detect any real particles in the vacuum's region of space. D. Scientists introduced a virtual electron and a virtual positron into a vacuum's region of space, but found that the vacuum did not then fluctuate. E. Scientists introduced a real electron and a real positron into a vacuum's region of space, but found that the total energy of the space increased by the energy equivalent of the mass of the particles.
