BBC ran a great segment demonstrating two objects falling in a vacuum at the same rate. The experiment was conducted in NASA’s Space Power Facility in Ohio and used a bowling ball and a feather to demonstrate the remarkable principle of physics. The facility used for this experiment, a space simulation chamber, is the world’s largest vacuum chamber. Originally built to be a nuclear test chamber, the huge room has thick concrete and aluminum walls and a huge series of pumps used to create the outerspace-like environment. To create the vacuum, the doors to the facility are sealed and air is pumped out until only about 2 grams of air are left inside the gigantic chamber (yep, there’s no oxygen in that room so entering…
