Objects fall at the same speed in a vacuum. Really.

One could build a mother of all vacuum tubes in there..imagine the moment of flashing 1000 kilos of getter material.

What a bunch of pussies they didn't even stay in the chamber for the experiment.

Terrific, good post.

Got to go to Pisa next week, this saves me a trip up the tower carrying a watermelon and a grape.

Ooh! I got tingly all over! Several times! Huge NASA apparatus! Cool experiment! ETC!

Add this to the list: "You know you're a nerd when"

I'm old enough to remember when Dave Scott did this on the moon with a hammer and a feather.

Yes! https://www.youtube.com/watch?v=5C5_dOEyAfk

...and I was thinking how expensive it must have been to do that experiment in the vacuum chamber! My favorite part is when the feathers hit the bottom and bounce around like springs.

All that proves is that if you're going bowling in space you'd better use a bowling ball, rather than feathers.

All that proves is that if you're going bowling in space you'd better use a bowling ball, rather than feathers.

But it's also useful to remember that if you're in outer space, and you're out of bullets, it's equally useful to fire your remaining feathers at near-light velocity.

...you know you are REALLY nerd when you know how to make a metal ball fall down slower than a feather...
