Putting 4 million suns in a black hole over New York is one thing, attempting to visualize spacetime is another. In terms of general relativity, spacetime is essentially a four-dimensional continuum that combines the three dimensions of space with the fourth dimension of time into a single entity.
In other words, instead of being a static stage where events occur, spacetime is dynamic and can be curved by the presence of mass as well as energy. One method to visualize spacetime is through the use of diagrams that represent the curvature of spacetime caused by massive objects. Objects like stars and black holes are capable of creating distortions in spacetime that affect the paths of other objects moving through it.
