Question

If gravity is caused by a warp in spacetime, does that make the Universe flat?

Answer 1

Explanation:

Gravity is the curvature of spacetime

Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein's view of the world, gravity is the curvature of spacetime caused by massive objects.

Answer 2

Answer:

Anything with mass—including your body—bends this four-dimensional cosmic grid. The warp, in turn, creates the effect of gravity, redirecting the path of objects that travel into it. The strength of gravity depends on the size of the space-time warp. The curvature of spacetime (not just space) is responsible for gravity. Literally, near heavy objects, the “future direction” points slightly down. So anything that moves forward in time will find its trajectory pointing down slightly. This takes the form of downward acceleration.
