What I read indicated the math for this had already been done or enough done to indicate this was plausible. Many years ago I also heard of another line of research done for which I cannot find that article anymore but it stated in a similar manner that we could effectively go Faster Than Light. The method was to create a field of I believe some kind of Electromagnetic Fields which in effect enclosed an object. The electromagnetic field enclosed an area of space time which was essentially the same as the other universes in space only it was on a much smaller scale. Physics indicated that Universes can travel faster than the speed of light whereas objects inside a Universe cannot. The theory was that an object inside this artificial small 'Universe' could therefore effectively travel faster than light by the artificial universe moving to a given point in the normal universe. Einstein's rule about Faster Than Light travel was not violated because the object inside the artificial small universe never in itself went faster than the speed of light. This is much like a fly inside a car. A fly cannot travel at 60 miles per hour but inside the car the fly can buzz around at a relative low speed but in terms of how far the car traveled in a given period of time, the fly got to the same place the card did while not actually propelling itself at 60 miles per hour. The people doing this research supposedly actually built a mechanism to create this artificial small universe and moved a spec of matter something like a centimeter or so to prove the propulsion could actually be done. The only problem again was they didn't have a power source great enough to propel the artificial small universe at the speeds necessary.
probably you're referring to the theory of that Mexican guy. and the other prof from Uni of Washington suggests that we don't have any idea how to generate and manage required amount of energy - which would have to be in planet-scale!! - to produce this kinds of fields, warps... whatever you name it, nonetheless the theory looks arguable.
(my post on previous page & https://www.npl.washington.edu/AV/altvw81.html
let's say it may be possible one day...
then again, it's not clear to me how to abstract this mini-universe (which inevitably would be produced with "our" universe's matter/energy) from our universe and it's laws. let alone physics theory, this contradicts elementary rules of human logic. there are even thoughts about communication packed in such "warps" to keep contact to Earth (or "base" wherever it is) instant or in reasonable lags. too much Star Trek?
BTW your "fly in the car" is not a good model. sum of speeds cannot be FTL (see Special Realtivity). but ok, Special Relativity goes to trash can in this case
a 1g accelerated spaceship would eliminate gravity problem for it's passengers and reach quite relativistic speeds in a few months. staff will have enough time to travel in a comfortable environment any far, based on how close their speed approaches "c" and how far their propulsion can maintain 1g acceleration against relativistic mass increase. pure technical and engineering questions, no SciFi. to me this looks a more realistic path to go than playing God and dreaming of own produced universes, matters, times and laws.
even if there were universes which move in unrestricted speeds relative to each other with their own laws, this shouldn't be a subject of natural sciences but religion or philosophy. i know people who believe in astral trip to x distance in zero time. so what?
