Abstract :  The inflationary scenario has become the standard

paradigm of early universe cosmology, but it is not

the only scenario which can explain the currently

available data on the large-scale structure of the

universe. I will compare inflation with two alternative

scenarios, the "Ekpyrotic bounce" scenario, and

"String Gas Cosmology". I will then argue that

there are severe obstacles to embed inflationary

cosmology into quantum gravity, and that the

alternative scenarios may be more promising"
