the enhancement of super-horizon curvature perturbations, during a matter contracting phase in combination with a short transitory period from the matter contracting to the HBB expanding Universe ...

For one, it explains why the cosmos appears geometrically flat: It's so big that, despite its overall curvature, any patch of the universe will appear flat. It also explains why regions of the ...

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.

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 ...
