1G for gravity can be simulated by spinning the work space the humans use we can survive in less than 1G environment...it's the 0G that is problem for humans! ;) also, we can survive in less than 1atm...actually the limit for normal functioning is 4000m altitude on Earth! ;) non-profit org.

actually the limit for normal functioning is 4000m altitude on Earth From your own link Chris:) http://wol.jw.org/en/wol/d/r1/lp-e/102004164 Many highland areas have become economic growth zones. The teeming millions of Mexico City live at over 7,000 feet [2,000 m] above sea level. Denver, Colorado, U.S.A.; Nairobi, Kenya; and Johannesburg, South Africa are at elevations of more than 5,000 feet [1,500 m]. Millions of people in the Himalayas live at over 9,000 feet [3,000 m]. In the Andes several large cities are over 11,000 feet [3,300 m] above sea level, and people work mines there that are 20,000 feet [6,000 m] up. With so many living in the highlands, the study of how the body adapts to life there has gained importance. What has been learned can deepen your appreciation for your body’s marvelous design. btw English spoken scientist use meters becuse it makes maths so easy... Isaac Newton did:) Humans need 1G to survive. Thats about 10 m/s². How much is that in feets/s²? And who's feets? |

btw English spoken scientist use meters becuse it makes maths so easy... Not scientists. Not even the SETI team... I wonder if a US foot is the same as an UK foot? I know that a US gallon is less than a UK gallon. Is it still called Imperial Gallon? And its very easy to do typos in this lame editor! Here we call a metre a meter and a gauge for mätare. We use umlauts instead of moving letters around. Much easier:) Hmm. meter {noun} [Amer.] |

I'm sorry, Issac Newton lived and died 200 years before the metric system was invented!!! I forgot:) Metric system – various loosely related systems of measurement that trace their origin to the decimal system of measurement introduced in France during the French Revolution. They had to change the value for the constant G in the Newton's law of universal gravitation. http://en.wikipedia.org/wiki/SI_base_unit The International System of Units has been adopted by most developed countries, however, the adoption has not been universal in all English-speaking countries. In a global World with different base units are still causing problems... Sometimes even disasters. |

It's very interesting how the gravitational constant was measured in the laboratory. An example of how a fiction allows us to understand and control things in our physical world. |

The gravitational constant, approximately 6.673×10−11 N·m2/kg2 and denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies. It usually appears in Sir Isaac Newton's law of universal gravitation, and in Albert Einstein's general theory of relativity. It is also known as the universal gravitational constant, Newton's constant, and colloquially as Big G.[1] It should not be confused with "small g" (g), which is the local gravitational field (equivalent to the free-fall acceleration[2]), most commonly for that at the Earth's surface. |
