Why are we weightless in space?
Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. The force of gravity is the only force acting upon their body.
What height does space start?

What does Zero G feel like?
Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time.
Do you feel pain in space?
In weightless environments there’s no reason for the membrane to shift, so the system goes a little haywire. This can be completely disorienting until you adapt to it. And until then, you’ll be space sick. Incapacitating discomfort, nausea, headaches, and more vomiting.
What G does to your body?

At what G Do you pass out?
A typical person can handle about 5 g0 (49 m/s2) (meaning some people might pass out when riding a higher-g roller coaster, which in some cases exceeds this point) before losing consciousness, but through the combination of special g-suits and efforts to strain muscles—both of which act to force blood back into the …
How much G force does a fighter pilot experience?
Fighter jets can pull up to 9 g vertically, and the more a pilot can take without blacking out, the better their chances in a dogfight. Some pilots wear “g-suits” which help push the blood away from their legs and towards the brain. People with the highest g tolerance are known as “g-monsters”.
Can you die from G Force?
The body is designed to pump blood upward, but negative gs force more of the blood to the head, causing vessels to burst in the eyes — a condition called “red out” — and, eventually, the brain. A extended force as low as negative 3 gs can prove fatal.
