What Cosmologist Wants From String theory

The most surprising difference for the quantum case is the so-called zero-point vibration" of the n=0 ground state. This implies that molecules are not completely at rest, even at absolute zero temperature.

When I looked at the issues strings presented of itself, the very idea of changing the way we percieve the basis of reality came into question. If strings were to exist where did they come from? This assumption, on my part asked me to consider then, that the very basis of this reality was drive by a quantum harmonic oscillator, and that there was never really any zero point in which to consider? Was this a logical assumption about how we would percieve the basis, from some emergent property that had to always exist?



This kind of thinking then forces you to consider what if this universe had always existed? How could it have ever come into being? Could such a realization have been embued into the string cosmology understanding, of the way this universe is operating?

So on a cosmological scale, we have this synopsis of events, as they have been shown in this following Picture taken from Beyond Einstein. Imagine then, how you might encapsulate this whole picture into a simple explanatory feature that trends this quantum beginning to cosmological end, in a cyclcial fashion worth speculating.



From this perspective ,it is with some consideration that we are directed again to Turok, Steinhardt in brane collisions. Or others like Gasperini and Venziano in, "The Pre-Big Bang Scenario in String Cosmology".
