3D Shapes
Not flat shapes like circles and squares, but solid shapes like cubes and cones ... GIRL 1: Now the next shape is a sphere. Try to make yourself into a sphere – a big ball!
Earth’s inner core isn’t just slowing; it’s also shape-shifting, study finds
Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the ...
According to Physics, Dyson Spheres Could Totally Exist, Scientist Says
A ring or sphere could, apparently, be stable if surrounded by the right sizes and gravities of other stars.

Earth's inner core is slowing down and changing shape
The Earth's inner core, long considered a solid and stable sphere, may be quite different ... causing changes in shape. These disturbances could also explain the gradual slowdown in the rotation ...
