I have a suggestion!

[Craftmaster]

Here are a Couple of Suggestions I have!

Protostars
Protostars are something I have wanted in a Universe sandbox 2 for a while,
It would be nice to see a star and planets being formed naturally. If you are not already working on this, then please do! 

Life Stages
What I mean by Life Stages, I mean like on a Habitable Planet a few dim lights will appear, meaning that the people on the planet are making Cities, and becoming intelligent!

This would be very hard to add into the game.

But maybe one day they will add this stuff.

These are both long terms goals for us...

"Life simulation is a highly requested feature and something we'd really like to do... that said... adding life in a way that fits the scientific and realist rigor we've set for the simulation will requires a number of new, complex features (some of which are already in progress) all working in tandem... So while I can't promise what the future will bring... we're certainly moving in this direction."

The same is true for star formation, we're working on the core feature necessary to make this happen.

What about gravitational ripples?

Maybe some way to add texture to the planet? For example the "death star" and make it so you need two textures; 1. the look of the planet 2. the elevation so that water doesn't completely cover the surface

And that black holes do the whole ring thing before sucking the object in- No, this might kill the computer and cause a BSOD epidemic
