presence of matter. If the curve is pretty weak, Newton's laws of gravity can describe

most of what is seen. Massive or thick objects generate a very strong gravity pull.

The most compact objects are theorized by relativity to have such a strong gravity

pull that nothing, not even light, can resist the gravitational pull. These objects
