what can be done to help humans endure significant g forces?

Off the top of my head, g-suits are used to assist in the circulation of blood; Check out the site below; US military does tons of research related to G forces for obvious reasons.

By the pull of earth's gravity

One big adjustment is to once again get used to an environment that has gravity.  In the gravity free environment of space movement is unhindered by gravity.  Back on earth muscles have to readjust.

Antigravity, but that hasn't been proven.  Magnetism works when you have two magneticaly charged objects.

Gravity is the basic force. There is also a positive feedback effect; the more massive a cluster becomes, the more strongly it draws other particles and clusters toward it.

the formula you need is Fg=Gm1m2/r^2.  so just plug in. G is the universal gravitational constant. so it's:\n(6.673 x 10^-11)(70)(70)/(1)^2 = 3.327 x 10^-7 N\n\nas you can see, this is negligable because people are not big enough to create a substancial gravitational force.

Teach them how to demonstrate centrifugal force by taking a metal coathanger, holding on to the hook and pulling the center of the straight part so it looks like a skinny oval with the hook on the bottom, put your finger in the end of the skinny loop away from the hook and hang the hanger on your finger so the hook is down, then balance a penny on the point of the hook and carefully spin the hanger around in a vertical circle.  The penny will stay balanced on the end of the hook.  Believe it or not, this works and if you practice it it's easy - you can even stop the coat hanger without losing the penny.  Try it!

What you're describing is called the 'grand unified theory,' or GUT. There are four known fundamental forces in nature that literally control everything--gravity, electromagnetism, the weak nuclear force, and the strong nuclear force. Science has been successful in uniting all of these except gravity.

Yes, wearing heavy clothing would help to make you stronger.  You are right, armor would be noticeable in this day and age, but placing metal plates, such as lead, inside your clothing would work.

According to the theory of energy conservation, it is impossible to create energy from nothing, thus, the only way gravity can be used to add energy to a system is by increasing the kinetic energy of two objects by accelerating them towards each other, a trade off of potential energy for kinetic energy.  This energy is generally short lived, however, as the two objects eventually collide and the kinetic energy from movement become heat from impact.  \n\nThe only way you could effectively harness the energy of gravity, is to discover where objects will impact each other, and then place a generator there which can make use of the energy resulting from the collision of those 2 objects.

It is not possible unless there is some external force to initiate or continue the movement. The initial movement will get off set and reduced  in course of time.

Well, I appreciate the fact that you include a waiver for many of the things that would make this task impossible, that helps a lot ;)\n\nIf some explorer were able to dig a hole straight through the center of the earth, the digger would slowly find the apparent effects of gravity decreasing as he or she approaches the center.  On the surface of the earth we feel a good, solid 1G because we have this huge mass effectively "underneath" us but our explorer would slowly be working his way down until only a portion of said mass is "underneath" them... the rest is above them and around them.  By the time they reach the center, they would essentially have a nearly equal amount of mass in all directions, all pulling with pretty much the same amount of force.  Yup, they'd feel like they were floating and would have trouble discerning any "up" or "down" by then.  When they start digging the rest of the way through, they are no longer digging "down", and the further from the center of the earth it will feel more like digging up.  By the time they break through to the other side, they're back to a nice steady 1G.\n\nI hope this helps you, and I hope you don't need the equasions.  We're talking about some serious calculus here and I'm not sure I'm up to that right now ;)\n\nDuckie

I suggest you build an anti-gravity lifter device that is able to float in the air without anything supporting it.\n\nhttp://www.amazing1.com/grav.htm

They will lose calcium, and atrophy.  That's why the astronauts must do such vigorous exercises; they are not working their skeletons just walking around, the way we do here under 1 g of gravity pull.

and gravity does what?\n\nand why don't you fall off?

The astronauts would be in zero-G for almost the entire trip causing the negative effects of weighlessness on their bodies.\n\nThe accereration of the spacecraft would indeed negate the problems with Zero-G by temporarily creating artifical gravity.  The problem lies in the fact that with the limited amount of fuel on the spacecraft, acceleration would only occur while the the engine was on. (a very short time with a chemical rocket)   \n\nOne solution would be to use a a drive that will burn during the entire trip.  One such drive is an ion drive (used on the recent Deep-Space One spacecraft to visit a local asteriod).  This drive would acclerate for most of the trip there creating a small amount of artifical gravity.

more than the magnitude of g-force the direction of g-force on our body matters;\nthe force the blood flows in our brain is very small but constant exposiure to a g-force of 10.2 or 10.3 the blood in our body stops flowing to the upper parts of the body (if we are lieing along anti parallel to the field of the gravitational field)blood stops flowing to aorta and vien and  of our upper body increasing the risk of paralysis,loss of senses and eventually death.
