B．Scientists assembled a super heavy 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 super heavy 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 vacuum did not then fluctuate.
