An amazing video on how gravity works!

[Tex]

So I found this video while mucking about with Veritasium and Vsauce videos. This teacher uses a system that is basically a large cloth suspended with clamps to represent space-time, and various weights, marbles, and other spheres to represent other masses.

As the objects weigh down the thread, they have a simulated gravitational effect on each other. This guy even demonstrates free return trajectories, why everything goes clockwise, and he even creates a planetoid-satellite system!

Please enjoy, it's pretty dang awesome!

I've always wanted to perform that experiment

Yes, the guy said the setup costs $100. I really want to do this too, maybe on an even larger scale. I think it's fascinating that he even managed to demonstrate satellite systems and even a free return trajectory.
