Time Travel, Hyperspace, Wormholes -- It's All Possible!

I am far from a scientific genius. In fact I have trouble grasping even the must fundamental aspects of quantum mechanics. So when a physicist says something about the constant speed of a neutrino, I tend to believe her and go about my business as usual.
Here's an exception: A story about the instability of wormholes and the inability of engineers to control them. There are some who disagree, but even they claim some fundamental hurdles will never be overcome because of human limitations.
I find this notion utterly and completely ridiculous.
A century ago we were unable to fly 300 people at a time, watch television or have reliable telecommunications. Computers? The idea was unknown to all but a few. At that time most people on the planet were still going to the bathroom in the woods and wiping with leaves and grass. And they liked it that way.
So, the idea that 21st Century physics is the end-all of what we can know and understand about the Universe and how we can exert our influence over it, is wrong.
Anything is possible. Some things are more improbable than others, but nothing is impossible.
