Why do galaxies have a spiral shape?
Why are galaxies spirally shaped?
Do any galaxies appear blueshifted? What's it like in between galaxies? How do scientists calculate the diameter of galaxies? How does Nöther’s theorem explain condensation to galaxies? Do all galaxies have a black hole? Why is there so much empty space between groups of stars (which we call galaxies)? Or in other words, how/why did galaxies form? What is the Milky Way Galaxy? Why the Milky Way is milky? Why are stars and planets spherical instead of having other shapes? What make galaxies to Travel Faster than speed of light? Do galaxies move through and displace the strongly interacting dark matter which fills 'empty' space, analogous to submarines moving through water? What's the Milky Way? What fills the empty space between galaxies? What is the Milky way? What is the Milky Way? How do we know that distant galaxies aren't made of antimatter? What is outside the Milky Way Galaxy? If galaxies are moving further apart at faster speeds could that in fact mean, they are being pulled toward something instead of being pushed away from each other? Does the Milky Way revolve around anything? Why is the shape of the known universe not sphere? What is a galaxy? What if dark matter and dark energy don't exist and it's something else pulling the galaxies apart? What could it be? Why are solar systems and galaxies flat? How does a celestial object bend space? Is the Milky Way a Blazar? Why are the farthest galaxies considered the oldest ones? Why are the shapes of planets and stars spherical? Why aren't they square or any other shape? What is a black hole in the center of galaxies? Also, what is singularity? Does the Milky Way Galaxy have an orbit? What about our universe? Do galaxies travel faster than the speed of light?
