Dan Burns explains his space-time warping demo at a PTSOS workshop at Los Gatos High School, on March 10, 2012. Thanks to Shannon Range from the Gravity Probe B program for creating the original demonstration which he shared with Dan in 2004.

Is the Earth getting closer to the sun because of its gravity?

The only thing that needs to be pointed out explicitly - objects "move" through time too, that's why they "start" moving together - their movement in time becomes apparent due to the curvature which makes their trajectories convergent.

I'd love two changes:
- somehow reduce the friction of this by a lot. This would be a matter of changing the involved materials. Not sure if anything as cheap could be more effective though.
- add extra degrees of freedom. For instance, perhaps it could be set on a freely rotating frame. Or perhaps it could even be put on a motor so you can control a base rotation speed, to partially counteract the friction. That would definitely be quite a bit pricier though.

Proof we exist in a simulation? 😝

Did I miss something? What governs the preferred way/ direction of orbit? Surely this isn't chance/chaos theory?

Well, there's a question that has always made me wonder. Describing gravity in the way that a massive object would make another object fall into its dragging-down curvature seems to me as assuming that there's another force of gravity outside (beyond) space-time that is causing the other object to fall into the curvature??

In other words, this model would never have worked without the actual gravity of earth, which is coming from outside the space-time fiber model.
