Hello. I'm wondering to know what kind of Force is it? Ok maybe is gravity 🙂
Sometime ago I was created this without know how.  Someone can help me?
I've tried a lot of things.
Thanks

Did you mean to post on the NASA forums ? 😉
Joking aside, not an astronomer myself, but at this scale it is mostly about gravity. It is the only one from the 4 foundational forces that acts on long distances.
Are you looking for approximated dynamics model, or "faking" it will be fine ?

Hi Peter. ahahuaha Why not. 🙂
Anyway. Ok, is gravity. I will like to do approximately dynamic model. I want reate the particles as shape, convert to volume and shading. 🙂 If I cannot do it. I will Faking it.

Definitely difficult. I will fake it. 🙁

Two cone emitters should do.

I will try to do something like. A shape modeled, similar to two cones. Using the particles goals. But, i want the particles on the edges of the cones, go away and don't stop .

Combination of gravity and dark energy 😋

You could create the cloudy/waterfall effects using a 2DFluidTexture and map it onto a couple of cones.

May the Force be with me. 😎

Do you know what that is by the way? Is it a star exploding or one that has a long time ago and is now becoming a black hole or neither? Understanding whether the forces are driving matter outward or back inward might help with your simulation processes.

Yes JeremyR i know what it is. I'm very passionated about the space and the stars and how is exsist. I'm a great fan of "Cosmos a spasetime odissey" 😄. THe main problem is figure out the scale. I have a lot of great and interesting results with maya and particles, but my workstation have only 64 GB ram and maya particles need a lot more. FOr this effects i think Houdini is the base for all. Using maya particle as volume, using the sphere render(arnold tab) is usefull, and make me proud of maya.
I was try with bifrost GRaph, but to me is now so technical, and i have no great effects, it is impossible to make artistic effects like maya particles or houdini.
Thanks

Yeah I think Maya particles would be out of the question and Bifrost is the way to go here inside Maya. You could use Aero in the Bifrost menu, this sets everything up for you automatically and you can render the points as spheres without going into the Bifrost graph window. I would also check out the Bifrost liquid over Aero as you'd get the nice clumping of particles as the particles attract each other. I also find it much faster than the Bifrost graph setup.

BTW is this a young black hole?

This is a Butterfly Nebulae. Is composed by gas expansed and a blackhole  nucleus that attract and repulse i think. I've use the newton force, but is difficult to manage.to do the best physical i need to expand and attract gradually by distance. Is a pain.
