Do you believe in the concept of Wormholes in space - ie tunnels with two ends separated by a transcendental bijection of the spacetime continuum?

I am undecided on that because I am not an astrophysicist like Steven Hawking and the mathematical skills needed to understand such things is beyond me.

For all I know back holes may be one end of a wormhole. Maybe the Big Bang that produced everything in this universe was a wormhole releasing stuff that somehow travelled here from another universe.
