Let’s agree to disagree. Wormhole travel doesn’t require high-speed (warping time and space). Sci-Fi imagination is a reality now. Just think about how your grandparents’ grandparents would view today’s technology. And that is a mere 100 or so years ago. No communication, horse travel.
Now imagine our technology (if we don’t kill ourselves) a thousand years from now. In fact you can’t, it’s impossible. No one at this point and time can conceive what the future holds as far scientific knowledge. Technological advancements in all fields are being cubed, advancing at faster, and faster rates.
Well... you mentioned faster than the speed of light so I responded. :-)
It’s an interesting topic. Once one looks into such things such as wormholes you realize that even if such things exist custom building one from point a to point b is not going to happen unless can travel to both points.
If someone has the technology to build such a construct then they could more easily terraform planets in our solar system. Not to mention that human navigation of a wormhole is surely fatal.
From a pragmatic standpoint building some devices even if possible seem unnecessary.
