How does the Earth move through and curve spacetime without displacing it?
How is spacetime curved if it isn't also displaced? How does the Earth move through and curve spacetime without displacing it?
What does space-time curvature mean? Is curved spacetime the same thing as the state of displacement of the strongly interacting dark matter which fills 'empty' space? How can we measure the curvature caused by a massive body on space-time? How do space and time bend? How does a celestial object bend space? According to the Albert Einstine the gravity is due to curvature of mass in the space time fabric what force make the curvature? How does time bent space? If Earth is in a round shape how is the ocean water still staying on Earth rather than slipping into the space? What is a curved line? If space-time is infinitely curved around a black-hole, does that mean we are inside the curved space-time of a black hole? Why does planets move in elliptical orbit why not in circular orbits? Why are clouds round and curved in shape? Why can't they be squares or triangles? Why does earth revolve in an elliptical orbit? It should be in a circular orbit. What happens if we go "up" in space, perpendicular to the solar system? Why does the earth revolve around the sun clockwise and counterclockwise around itself? Relativity (physics): According to Einstein, light bends, because space is warped.  If light has little or no mass and cannot bend from gravity, how can space be warped if it has no mass at all? If Einstein's theory of general relativity says that gravity is the result of curved spacetime and that matter, such as a planet, has no force whatsoever that pulls other matter towards it, how are we able to walk on the Earth without falling off? Is there a force pushing on us? Why is the earth round? How does the gravitational force cause the bending of space? How would the pull of gravity be like if the Earth was shaped like a pyramid? If I orbited around the Sun once, how many Earth years would have passed due to gravitational time dilation? What does "bend space and time" mean? If you were at the center of the Earth, would the gravitational pull in all directions stretch you apart? Why doesn't Earth crash to the Sun thanks to gravitational pull? Could space-time be intentionally bent in front of a spacecraft to make it travel through space faster? If gravity is caused by warped spacetime, what dimension is it being warped? The 4th dimension? What would the world be like if the land masses were spread out the same way as now - only rotated by an angle of 90 degrees? Is there any case where the surface of the earth can be assumed to be a non-inertial frame? Why the path of planets is elliptical not circular? How can space-time be described as a fabric that bends and warps if it is three-dimensional?
