Why can't current theories describe what happened during the Planck era?
A) We do not yet have a theory that links quantum mechanics and general relativity.
B) We do not understand the properties of the antimatter that would have been produced at this time.
C) We do not yet have a theory that links the weak and electromagnetic forces.
D) We do not yet have a theory that explains how the universe underwent a rapid period of inflationary expansion.
E) The Planck era was the time before the Big Bang, and we cannot describe what happened before the beginning of the universe.

Current theories of physics cannot explain what happened during the Planck era because we do not yet have a theory that links quantum mechanics and general relativity. The laws of physics as we currently understand them break down at the incredibly high energies of the Planck era, and a unified theory that can describe the behavior of matter at such extreme conditions is still being sought.
