You should watch The Expanse, a very good TV show.
Their ships accelerate at a comfortable level to generate gravity for half of the destination, and then "flip-and-burn" by accelerating in the opposite direction at the same comfortable level to generate gravity.
- dmichulke 9y agoThe ISS weighs 440t and to get 1g there by acceleration you'd need to constantly apply a force of ~4.4MN (meganewton), that's a tenth of a Saturn 5 at lift-off. Not sure we can do that for an extended amount of time (read: a few hours) without bringing along lots of fuel That or we invent that special drive of that dead Martian.
- akvadrako 9y agoThat only works inside the solar system. The energy requirements to accelerate for a year are enormous. With 100% efficient engines, you would need something like a reaction mass the size of Jupiter. On the plus side you quickly approach c. At constant 1g acceleration / deceleration, Andromeda is about 28 years away.
- crowbahr 9y agoI'm assuming you mean subjective time right? Because you can't cover 2.578 million light years in only 28 years moving at c from the reference frame of Earth.
