The scientists' calculations show that this universe mode's properties, such as the curvature of space and the microwave ...

On the one hand, we have Einstein’s theory of relativity. That describes the largest structures in the universe in terms of curvature of space and time. On the other hand, we have quantum theory.

This might change our understanding of the universe. Scientists have developed ... of a black hole where the density of matter and the curvature of spacetime become infinite.

The amount of matter within the universe sculpts its overall curvature. And space-time itself can be either expanding or contracting. When Einstein announced general relativity in 1915 ...

Cosmic inflation is a faster-than-light expansion of the universe that spawned many others ... either in on itself like a ball (“positive” curvature) or out on itself like a saddle ...
