Absence of gravity

A "stationary" micro-g environment2 would crave travelling far abundant into abysmal amplitude so as to abate the aftereffect of force by abrasion to about zero. This is the simplest in conception, but requires traveling an astronomic distance, apprehension it best impractical. For example, to abate the force of the Earth by a agency of one actor one needs to be at a ambit of 6 actor km from the Earth, but to abate the force of the Sun to this bulk one has to be at a ambit of alike 3700 actor km. (The force due to the blow of the Milky Way is already abate than one millionth of the force on Earth, so we charge not move abroad added from its center.) Thus it is not impossible, but it has alone been accomplished by a few spaceships such as Voyager 1, which do not acknowledgment to Earth. To abate the force to one thousandth of that on Earth one needs to be at a ambit of 200,000 km.

Location Gravity due to the Earth Gravity due to the Sun Gravity due to the blow of Milky Way Total

Earth's apparent 9.81 m/s2 6 mm/s2 200 pm/s2 = 6 mm/s/yr 9.81 m/s2

Low Earth apogee 9 m/s2 6 mm/s2 200 pm/s2 9 m/s2

200,000 km from Earth 10 mm/s2 6 mm/s2 200 pm/s2 up to 12 mm/s2

6 actor km from Earth 10 μm/s2 6 mm/s2 200 pm/s2 6 mm/s2

3700 actor km from Earth 29 pm/s2 10 μm/s2 200 pm/s2 10 μm/s2

Voyager 1 (17,000 actor km from Earth) 1 pm/s2 500 nm/s2 200 pm/s2 500 nm/s2

0.1 light-year from Earth 400 am/s2 200 pm/s2 200 pm/s2 up to 400 pm/s2

From stationarity the force from "the blow of the Milky Way" would account a chargeless fall, accoutrement a ambit of 100 pm in one second, 360 nm in one minute, 1.3 mm in one hour, 70 cm in one day, 37 m in one week, 100 km in one year, and 10,000 km in 10 years (at a acceleration at that aftermost area of 6 cm/s).
