Query: A Solution to the Fermi Paradox: The Solar System, part of a Galactic
  Hypercivilization?   I introduce the Fermi Paradox and some of its solutions. Then I present my
own solution which includes two proposals called the Subanthropic Principle and
the Undetectability Conjecture. After discussing some consequences of this
solution, I make some comments about brane world scenarios and their potential
to strengthen the Fermi Paradox. Finally, in the appendix I have included some
questions and answers that came up during this Forum. --
  En primer lugar introduzco la Paradoja de Fermi y algunas de sus soluciones.
Luego presento la solucion que yo he propuesto, que incluye dos hipotesis que
denomino el Principio Subantropico y la Conjetura de Indetectabilidad. Despues
de discutir algunas consecuencias de esta solucion, paso a hacer algunos
comentarios sobre las teorias de universos branas y su potencial para reforzar
la Paradoja de Fermi. Finalmente, en el apendice incluyo algunas preguntas y
respuestas que surgieron durante este Forum.
