The branch of astrophysics that studies the origins and structure of the universe

Usage examples of cosmology.

Vafa, and other physicists have made use of these ideas to suggest a rewriting of the laws of cosmology in which both the big bang and the possible big crunch do not involve a zero-size universe, but rather one that is Planck-length in all dimensions.

String cosmology, as we shall discuss in Chapter 14, is a field very much in its infancy but one that holds great promise, and may very well provide us with this easier-to-swallow alternative to the standard big bang model.

All the data we possess confirm a theory of cosmology capable of describing the universe from about a hundredth of a second ATB to the present, some 15 billion years later.

Currently, research on the implications of string theory for cosmology is at an early stage of development.

But, because of difficulties in performing fully trustworthy calculations in such extreme situations with our present understanding of string theory, our work only provides a first look into string cosmology, and is very far from the final word.

Gasperini and Veneziano have, in fact, come up with their own intriguing version of string cosmology that shares certain features with the scenario described above, but also differs in significant ways.

Then, through the standard expansion of ordinary big bang cosmology, this patch can account for the whole of the universe with which we are familiar.

We should require that our ultimate theory give a cogent cosmology within our universe.

As we have discussed, superstring cosmology is a young field, even by the youthful standards set by string theory itself.

Accordingly, the dogmas of Christian philosophy theoretically contain the monotheistic cosmology, and practically the rules for a holy life, which appears as a renunciation of the world and as a new order of society.

In the cosmology of the Apologists the two fundamental ideas are that God is the Father and Creator of the world, but that, as uncreated and eternal, he is also the complete contrast to it.

They connected the Christology with the cosmology, but were not able to combine it with the scheme of salvation.

The place of these is taken by the results of speculative cosmology, which, though themselves practically conditioned, do not seem to be of this character.

To this rationalism, the objects of knowledge are unvarying, ever the same: even cosmology attracts interest only in a very small degree.

This is an exploration not just of cosmology but of fundamental physics.
