IDK how gravity or topology works.

1 dayA planetary mass disc would collapse into a sphere. Gravity works towards the centre of mass, so it makes sense that it becomes a sphere once the force is great enough, where the distance from said centre of mass is nearly equal from all points on the surface. it’s the reason why smaller objects are usually oblong and weird shaped (e.g. asteroids) while larger objects are close to spherical (e.g. Pluto!)
And what do you mean by “uniform gravity”? If you mean for a theoretical person on the planet, it would not be uniform on the edges as you have an imbalance of forces towards either side, while in the centre it is symmetrical, an equal amount of mass on either side. On a perfectly spherical planet, it would all add up to a downward force on any point on the surface

One interesting note, some planets like Jupiter and Saturn spin so fast they bulge in the equator, making them a little less spherical than normal!
edit: All the planets spin and have this bulge, but Jupiter and Saturn have the most noticeable bulges of the Solar System planets due to spinning the quickest
