How can the CMB be used to measure the curvature of the universe?
What does space-time curvature mean? How do they measure gravity in other planets and stars? How can we calculate the expanding rate of the universe if it has no center? What is the topology of the universe and is it worthy to represent the complement of solar system in the universe as a big CW space? What is spacetime? How is it curved? How is the gravity of other planets measured? According to the Albert Einstine the gravity is due to curvature of mass in the space time fabric what force make the curvature? What is the shape of the universe, conical or spherical? What is the radius of the universe? How do scientists calculate the diameter of galaxies? Can we calculate the mass of the universe? How is the expansion of the universe consistent with General Relativity? How much of the universe has been mapped out? At what altitude do you see the curvature of the Earth? What is the radius of the black hole at the center of our galaxy? Is curved spacetime the same thing as the state of displacement of the strongly interacting dark matter which fills 'empty' space? How does the Theory of relativity explain the expansion of the universe? Is Milky Way near the center of the observable universe or close to the edge? Considering the 'Zone of Avoidance', and the fact that the Earth in on the same plane as most of the Galaxy, how do we know the size and shape of it? How is the mass of the universe calculated? How does a celestial object bend space? What is the decay function of the large-scale structure of the cosmic microwave background? How do scientists calculate the distance from Earth to a star or galaxy in space? What is the Topology of the Universe? Is there gravity in space? How many dimensions does the universe really have? Is the Universe a sphere? If not, which shape it is? How do we know that? Does universe have a center of mass? Is space-time-light-mass-gravity related? How do I find center of gravity of the world?
