I'm pretty sure that is not v and c, its v^2 and c^2
And good point made by saral is the time dilation.

It is impossible to go faster than the speed of light, because there is a thing called time dilation, where the faster you go, the slower time travels (for you personally).
You can also prove that if you travelled at the speed at light (hypothetically) in a straight line, you could start from point A and come back at the same position but by then the universe would have collapsed or something.
cbf to check Stephen Hawking's book right now =p

The big bang was created from a singularity. How do you know what caused the singularity? In a universe, for all practical purposes time starts at the big bang because any event before it has no effect on the universe after it. Thus, t=0 refers to the big bang.
Thus you can't say how the singularity causing the universe was caused. All you can say that physical evidence states that the universe was at a singular point once in the past. All the mass concentrated at one point.
This singularity at t=0 underwent an event we call the big bang. That is all that we (or at least I know) as of now

err?
If you mean travelling faster than light, some particles are known to do that for reasons unknown as of now.
As for the warp bubble concept, it actually states something like if we had a protective bubble, we could create warp holes in the fabric of spacetime and go from A to B in a non linear fashion.
Like if you have a paper. Make 2 points A and B on it. What is the shortest way to go from A to B? A straight line between A and B.
But what if you were allowed to bend the paper and join the points together? Shorter distance, ain't it?
That's the concept. I'm sure there is some math done on it but none with any promising practical interest or with math that the laymen would understand
