http://golem.ph.utexas.edu/string/archives/000424.html#c001571

a detailed summary of his newest article on old (and new) and deep questions
in (string) cosmology, emphasizing the notion of the "beginning of time" in
cosmology as well as the very nature of space and time.

If anyone feels like thinking about philosophical questions on the basis of
current ideas in cosmology and string theory he or she will certainly enjoy
having a look at what Ruediger Vaas writes.

In particular, Ruediger is challenging string theorists to provide him with
demonstrations that spacetime is a secondary and derived concept in string
theory and he is wondering about the question if and in which sense strings
can be considered as being "elementary".

Interesting replies have a good chance of being incorporated in future
articles about aspects of cosmology and quantum gravity in the popular
German science journal "Bild der Wissenschaft"
