OUTER SPACE PARADOXES

2.1 A Helium Balloon in a Space Shuttle

Problem. Two astronauts, Al and Bob, are strapped to the opposite ends in a space capsule, as in Figure 2.1. Al is holding a large helium-filled balloon, and everything is at rest. Now Al pushes the balloon, which begins to drift toward Bob. Which way will the capsule drift, as seen by an observer hovering in space outside the capsule? Since the astronauts are strapped to the walls, let's consider them part of the capsule.

Figure 2.1. Which way does the capsule move after Al pushes the
balloon?
