This could be interesting!
The speculation is intriguing.
True, but our current design space vessels are only designed for relatively short hops.
This does not mean that they are the fastest we can build.
I've seen that a solar sail powered craft could be propelled to a significant percentage of light speed because of the constant accelaeration.
