The study of cosmology has long been fodder for dialogue and argument between science and religion. This chapter guides the readers to understand the

Is general relativity a cosmology?

Apart from the fact that general relativity is currently only one out of many different geometric ways of describing an interaction of spacetime geometry and matter, there are areas in cosmology where even the very notion of spacetime and that of a fundamental timelike field are probably too restrictive to use.

What is mathematical cosmology?

The beauty and enormous variety of ideas of modern mathematical cosmology have their roots in the different kinds of geometry required to be developed and studied in parallel and in conjunction with those cosmological ideas for a better understanding of different aspects of this most majestic of fields of theoretical physics.

Which cosmologies share the feature of continuous creation?

Steady-state cosmologies sharing the feature of continuous creation include:

the one by W.
McCrea proposed in 1951 [ 55 ], see also [ 56 ], that incorporated this idea within general relativity as cosmic tension (negative pressure, p = −ρ p = − ρ) leading to a global state of constant density.
