Dust creates planet

first try

computing step 1s; 1frame/s; dimension = 50km, G= 100 N m[SUP]2[/SUP] / kg[SUP]2[/SUP] ; masses : 1 to 100 kg initially

scale if proportionnal to masse**(1/3)

Cool test. I’d be interested to see it running faster on a longer timeline.

really interesing. Do the particles bounce off the borders of the render?

Wow this is a cool idea. How accurate is
blender’s physics?

HI
I don’t use particles because I can(t assign value/key to their position
I don(t use physics for that just equations
It’s an adaptation of a little job of a friend in 3ds
It would be nice to see it with particles

[ris, I do not think that they are bouncing off the walls, rather they are all orbiting the ever changing center of mass for the whole group.

This is really neat, how long did it take to render/calculate? My attempts doing (3D) models of gravitational interactions are usually very slow, even with only a couple objects and only turning out the coordinates. I can imagine for something like this it would take rather longer. I would be interested to see some more details of exactly your methods.

Now to put them all (plus billions more) into a huge nebula, and try to make a star system!

Has anyone seen the experiment showing how dust clumps together due to electrostatic forces?

Cool, also pretty sure there was a monkey head floating by at about 2:10" :wink:
