Ummm…. heavy G acceleration is not necessary. Acceleration at levels we’ve already demonstrated an easy ability to handle gets you up to high velocities quite sufficiently. If you could accelerate constantly at 1g, you’d reach Mars in something like two days. At 5g acceleration, which is something humans can handle without too much stress, it would take roughly two months to reach light speed.

If I'm on the Rossy and Inaros shows up... Heavy G acceleration becomes very necessary. IMO.

Indeed, the only reason we use high G on liftoff is because any time we waste getting to orbit costs us 1G negative the whole time.

Note that Special Relativity means you won't reach light speed, though it will seem as if you blow right past it as your rapidity increases.
