Galileo’s Famous Gravity Experiment | Brian Cox | BBC Two

You probably know that two objects dropped in a vacuum fall at the same rate, no matter the mass of each item. If you’ve never seen a demonstration of this, then you really should, because it’s incredible to watch. Here is perhaps the perfect example, brought to us by physicist Brian Cox. He checked out NASA’s Space Simulation Chamber located at the Space Power Facility in Ohio. With a volume of 22,653 cubic meters, it’s the largest vacuum chamber in the world. In this hypnotizing clip from the BBC, Cox d
