Is the Universe a sphere? If not, which shape it is? How do we know that?
Why is the shape of the known universe not sphere?
Why are stars and planets spherical instead of having other shapes? Why are planets spherical? Why do extraterrestrial bodies always appear as a spherical shape? Why not square or cylindrical? If there is no gravity in space, why are planets spherical? Why are all planets spheres? Why are most planets sphere? Why do galaxies have a spiral shape? How do flat earth believers explain the spherical shape of other planets and moons? Why is our solar system or milky way almost flat? How and why are planets spherical? What makes them round? Can a sphere be represented in form of 2D? Is Ω < 1 = The shape of the Universe? Why can't planets be different shapes? Why are galaxies spirally shaped? Is there a point of no gravity inside an empty semi-sphere? If space (the universe) is a sphere or saddle shape, then what is outside of that? What do you call the empty space outside that comes after? Why is the Milky Way Galaxy spiral? Why are solar systems and galaxies flat? How did scientists calculate the diameter of the universe? Do spheres actually have 8 sides? What is the shape of the earth? Why does a human heart turn spherical in space? What is the shape of a wormhole? Is it necessarily spherical? Is Earth a celestial body? Why does even NASA show the Solar System as on a plane? It's all 2D - aren't our celestial neighbors surrounding us in 3 dimensions? If all the mass in the universe was condensed into two separate and equal spheres, would they remain in perpetual orbit around their center of mass? How do you describe the size of the known universe? Where did the mass of the universe come from? Atomic structure, the solar system, the Milky Way are all planar, therefore the universe is planar. Anything in motion has one predominant direction and observations indicate universe to be expanding. Is this expansion more flat in nature? Why the path of planets is elliptical not circular?
