Elementary Particle Physics and General Relativity relate respectively to the very small and the very large. But they are both essential in trying to understand the structure of the universe, especially at the very first instants. Some of the key ideas involved in this juncture of the very small and the very large are illustrated.

Keywords:
elementary particle physics
general relativity
extra spacetime dimensions
gravity waves
the universe as a membrane
