If there is no gravity in space, why are planets spherical?
Why are the shapes of planets and stars spherical? Why aren't they square or any other shape?
What is the shape of the universe, conical or spherical? Why are clouds round and curved in shape? Why can't they be squares or triangles? Why don't planets have phases like the moon? Shouldn’t the shape of the universe be a 3D sphere? Why are giant stars red, and smaller stars white or blue? Why do all planetary systems orbit stars? Why are Newton's rings circular in shape? Why not square or any other shape? Why do the Sun and the Moon appear exactly the same size, aren't the chances astronomical? Why do galaxies have a spiral shape? Neil deGrasse Tyson says the earth is pear shaped. Why do images of earth show it as round? Do spheres actually have 8 sides? Why is the universe not a sphere? Why is there so much empty space between groups of stars (which we call galaxies)? Or in other words, how/why did galaxies form? How do they measure gravity in other planets and stars? Why do the Moon and Sun seem to be of the same size visually from Earth? Why are solar systems and galaxies flat? Why are most planet orbits in our solar system on relatively the same 2D plane? Why don't all planets have rings? 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? Why are galaxies spirally shaped? Why is our solar system or milky way almost flat? Why is the earth's orbit around the sun almost circular? Do all planets have to orbit a star? When flying, why does it look as if the ground has many perfect shapes? How are masses of celestial bodies measured? How do flat earthers explain the rotation of planets as seen through telescopes? Why do sun and moon have the same apparent size, when viewed from the earth? If Aliens are not found yet, how do people depicting them in such many shapes? Why do they always depicting aliens in a weird shapes? Why are snowflakes symmetrical? Is the Universe a sphere? If not, which shape it is? How do we know that?
