Jul 29, 2013 · "1g of thrust" pointed straight up will balance gravity, and result in you floating. "1g" (as I read it), is the acceleration caused by the Earth's gravity; if that's how you actually define it, then your acceleration decreases as you get further (and 'feel less pull') from Earth. Of course, you don't need to point straight up, and TidalWave's assumption …

Jun 16, 2019 · A useful rule of thumb is that 1G acceleration is about the same order of magnitude as 1 light-year in relativistic units. This means that anyone going a lot more than 1 light-year while accelerating at 1G is basically going at the speed of light, while anyone going a lot less than 1 light-year doesn't have to worry too much about relativistic effects.

Sep 1, 2024 · So if the astronaut is experiencing a constant 1g acceleration, how much time would pass for them before an outside observer would measure their speed at .9999C? I saw this question and noticed that an astronaut experiences acceleration a little differently than an observer due to relativistic effects.

What radius and rotation would be needed to produce 1g consistently from the floor to a height of about 6ft (2m)? Infinity. Technically there will always be a vertical gradient of artificial gravity. Realistically, people will not care. Even with a radius of 224 m the difference isn't much.

This being said, you never actually stop accelerating. Your acceleration may get so low that you can't measure it. As for the observer on the spacecraft, they will still experience the 1g of acceleration - as in their frame of reference they aren't going at/near the speed of light.

Jul 15, 2016 · The concept is well known from (science-)fiction (sometimes named "Torchship") and the artifical gravity provided is actually sort of a side effect. The main benefit of a ship able to accelerate at 1G 1 G fo a long time would be the speed with which it can travel across the Solar System - Mars in two days, Jupiter under one week.

Jan 26, 2022 · So, you'll need to accelerate continuously at 8.91m/s2 to get 1g? But no engine is powerful enough to achieve this in a near future. I wonder what power/thrust you'll need for example to get 5m/s2 a large mass like a starship (1.000 metric tons)?

Hypothetically, if you could travel sufficiently close to the speed of light, you could not only exit the galaxy, but circumnavigate the observable universe in what would be less than a human lifespan in ship-time, due to time dilation.

Dec 10, 2018 · I've seen some calculations of the energy requirements of 1G propulsion, which are obviously huge, but at least theoretically achievable...but what about propellant? Somebody check my math, but it seems like you could minimize propellant with high exhaust velocity, but there are both engineering and physics limits to that, too.

Feb 6, 2021 · If we assembled an array of today's best ion thrusters in orbit, (the x3?) how many would be needed to accelerate a 1000 tonne spacecraft at 1g? I'm thinking Space Tug, for repeated Mars missions.
