So one of the ideas I've come up with for system to system travel, in the early colony stage of my world, is using fuel boosters to start the journey and then to reach the required speed for the colony ship to reach the next system, using solar sails.
Is this a plausible mechanism for inter-system travel?
The storyline will be making no use of hyperdrive/wormholes etc, however later on there will be the use of anti-matter/ion drives. But this is for the expansion era of the story.
I was thinking the original colony ships in my timeline would involve some 'sketchy' at best cryo sleep with occasional failures. The technology would have been developed as an alternative to riskier medically-induced comas.
I'm aware that the time required to traverse from one star system to the next would be quite large. But this age of expansion (in my universe) would be what sets into place the colonial divides in religion/science/design and political views.
