A misstep of local infinitesimal motion (LIM) of dynamic spacetime can happen once in several billions of years. Initially, this is manifested by a really big bang (BB). Subsequently, its dying echoes seem to reverberate forever spreading outward permeating the ocean of space and time. Its remnants are partially responsible for the detected cosmic microwave background radiation (CMBR) http://zebu.uoregon.edu/~imamura/123/lecture-1/cmbr.html . This was discovered by Arno Allan Penzias (1933- )http://en.wikipedia.org/wiki/Arno_Allan_Penzias and Robert Woodrow Wilson (1936- )http://en.wikipedia.org/wiki/Robert_Woodrow_Wilson. Both shared the 1978 Nobel Prize for physics. If George Gamowhttp://en.wikipedia.org/wiki/George_Gamow had not died 10 years earlier he would have also shared the prestigious prize since he predicted CMBR when he and his associates formulated the BB theory in the 1940s. The real truth behind this cosmic oops still lies safely hidden within the LIM. On the other hand, its relative imaginary truths are still being explored by theorists of both general relativity and quantum mechanics or quantum field theories. None has yet uncovered the ultimate absolute truth about the universal oompah oomph oops.
The single reason for these failures to locate the real truth is the undeniable fact that LIM can only be sufficiently and completely described by real numbers. The use of complex and imaginary numbers would only complicate the mystery. For examples: Stephen Hawking http://en.wikipedia.org/wiki/Stephen_Hawking used imaginary time to describe spacetime events before the BB. Roger Penrose http://en.wikipedia.org/wiki/Roger_Penrose used imaginary twistors to describe the naked singularity. Together, they published The Nature of Space and Time in 1996 hoping to resolve a 1969 conjecture by Penrose known as the cosmic censorship hypothesis.
