If you accelerate with g=9.81 m/s^2 then you'd need
(300M/9.81) seconds which is ~30581040 seconds ~ 8495 hours ~ 354 days, so you could at least accelerate with a moderate 1g in approx. 1 year to the desired velocity.
This calculation is probably wrong because Newtonian calculations are like that (wrong) when they get close to c.
However, it deserves bonus points for
+ having exactly earth's gravity in the ship
+ travelling "up" all the time, making you feel like in a huge elevator.
However, I'm not sure whether you'd consider 354d as fast enough :)
- meric 12y agoIf you see my first two links you'll see from the astronauts point of view they can accelerate indefinitely with no penalty besides chance of colliding with matter on the way. Accelerating at 1g for two years and then decelerating at 1g for two years means you will travel 3 light years in 4 years. Acceleration beyond 1g will speed this up from the astronauts point of view. At 2g it would take only 2.5ish years to reach alpha centauri from the travellers reference.
