From what I've read, String Theory is a theory of everything, unlike some of the other quantum gravity theories. That means that String Theory explains other particles and fields including gravitons. So String Theory is a quantum gravity theory because it includes gravitons.
But I was wondering, what is spacetime in String Theory? Does it exist as a separate entity? Is there some special gravitational gauge field?
Or does the GR concept of spacetime not appear in String Theory?
How does the concept of time appear in String Theory? Is it like quantum mechanics or GR or something completely different?
