The technology involved would be fascinating as would the history of its development.
The possibility of interstellar and intergalactic travel, exploration, migration and commerce may seem unobtainable to many but I am willing to believe that it can be done.
Correct me if this is wrong but my quick search tells me that the Sun's nearest known stellar neighbor is a red dwarf star called Proxima Centauri, at a distance of 4.3 light-years away.
This calculates as 40,681,440,000,000 kilometres.
Imagine the velocity needed to reduce travelling time to the Proxima Centauri system from 4.3 light years to 4.3 months, or days, or hours, or minutes.
I'm told the Andromeda Galaxy located at a distance of 2 million light-years away is our nearest major galaxy and is of comparable size to our own, but we must reduce travelling time to at least 2 years to make it a viable commercial proposition.
Two years to cover a distance of 2 million light-years is a big ask. That's about 2,750 light-years per day or 114.5 light-years per hour.
But get the sums right and centuries from now mankind could be crossing the Universe at zillions of light-years per second.
