re: Do you accept the notion of the Big Bang as the origin of our universe?

The speed-of-light barrier applies only to the movement of matter and energy through space. It has no relevance to space itself, except that perhaps it's space that applies the speed-of-light restriction to matter and energy.
The discovery of the Higgs Boson in 2012 confirmed that the Higgs Field exists and is a physical entity. Space is made up of the Higgs Field and seems to be independent from the field that generates matter and energy. Thus it isn't subject to the speed-of-light restriction itself.
Before inflation there was no space though (big assumption). The Big Bang was the inflation of space itself which carried the remaining matter (after the matter/antimatter collisions wiped most of everything out), so since that is space itself that is "blowing up" so to speak it's not traveling through any kind of medium, it would be traveling through true nothingness. As a result would it be possible for space itself to travel faster than light?
I'm sure I'm totally off base on most of that..

Well, we don't yet know what existed before the inflation/Big Bang. M-Theory says two branes bumped together to iniate the BB.

It's easier to just think of space expanding, rather than trying to account for what it is expanding into. It's impossible to define nothingness without making it something.

Guth's Inflation Theory indicates that space can expand much, much faster than the speed of light. In fact, the Hubble Horizon is the edge of the visible Universe. The horizon is the boundary between particles that are moving slower and faster than the speed of light relative to an observer at one given time. Beyond the boundary we'll never see anything, even the light that's emitted.
As space expands faster and faster, eventually everything beyond our local galaxy will be invisible to us. That is unless something weird happens to stop or reverse the expansion.
