Space

A green wireframe sphere, representing Earth, shrinks and moves to the left as blue text appears at the bottom, reading "SPACE IS BIG. REALLY BIG. YOU JUST WON'T BELIEVE HOW VASTLY, HUGELY, MIND-BOGGLING". The scene then expands to show the sphere orbiting within a wireframe cube, which then opens to reveal a larger system of concentric orbits around the central sphere, all set against a black background with the word "INTRODUCTION" in blue at the top left.
