Do not believe it? Try it yourself!
Of course, if you try your own home, perhaps, from the same height release the bowling ball (for the sake of brevity, let's call it an apple) to reach the floor much faster than a feather. Maybe the BBC 2 channel popular science show host Brian Cox following statements decided to make fun of us?
Definitely not. Gravity and an apple and pen works exactly the same. And that gravity carry out their work and show what you really are able to, should first be removed from the room ... the air, which prevents the pen.
Just as was done in the NASA experimental research center "Space Power Facility (Ohio, USA). This - the largest on the planet vacuum chamber. Of the huge room was pumped out about 30 tons of air and create a vacuum close to the space. Here it's apple and a feather dropped like a stone into the moss - absolutely the same speed.
Of course, the picture is not as impressive as throwing objects like the moon, but still looks damn impressive.
