Time and Space

    When we talk about the creation of the physical universe, does that include time and space? In other words were time and space themselves created along with the physical universe?

    Yes, according to the standard theory. Note that you need mater or energy in order to define distance (between two particles, for instance) or time (between two events), so that space and time can not be defined without mater/energy.
    On the other hand, there is an increasing number of models that do not require a creation event and are not ruled out by cosmological observations...
