Lets say you lived in a gravitational experimental room

I got this idea from Dragon ball Z a long time ago and thought about it recently.

Lets say if you were to live in a experimental facility where the gravity changed every week or so and increased just enough for you to survive and addapt to it. After surviving in this facility for so long, you forget how much gravity is actualy pulling on you towards the floor. The only thing that is different however is that small things drop like bullets to the ground, so you have to be very carefull not to drop anything on your feet.

Once you've finished with this experiment, you are then released back into the open to your original climate and gravity outside the facility.

Would you think it'd be easier to move around?
Would you jump higher?
Would your physical appearance change?

However, from knowing how much of human blood is made up of Iron, and other physical compounds. It's unclear to say if you will die from being in this facility for too long. The iron in your blood might weigh down on your vains and cause you to bleed internaly. The food you eat may cause you to have multiple ulcers, and you might not be able to use the washroom due to major injuries due to the high gravity.


How do you picture this happening? Would the human body be able to addapt to ever changing gravity?

I mainly ask this question because "IF" humans were to live on other worlds, the other worlds so to speak may be larger than earth and have different gravitational tolls on the bodies of those who walk on them.

With the insane amount of pressure and harm it'll cause on the human body, which would probably cause a TON of health issues and physical ailments, aside, IF a person were to undergo "testing" under higher gravitational pulls for long amounts of time, then yes, they would be significantly stronger and be able to perform higher amounts of feat that a normal human being.

However, such an experiement in real life would cause more harm to the human body than good. In fact, it might even kill a person before they can "test" anything.

If this were to be put to the test, wouldn't it be safer to assume that in order for a human to survive such conditions, the gravity would slowly have to be increased over a very long period of time? Like 1.1x earth's gravity for a few years, then 1.2x for a few years, so and so forth.... I think given circumstances like that, it may work out a bit better. However.... with the way I see it, instead of over a few years, this would have to be done over several lifetimes, with new generations being born in these areas of higher gravitational force. Would take hundreds, maybe thousands of years I believe.

That is, given we actually bother with the "evolution" route, instead of the "using technology to find a workaround" route.

It's gunna be like natural selection. The strong people who are fit can adapt a little, and then their kids might be able to adapt to a smaller degree higher gravity, and so on.

No way can any Joe Shmoe do it though. And in fact, I doubt one human, unless like extremely physically fit, can change the second time for the higher higher level of gravity.

1) No. Your muscles are undeveloped and no longer fit to withstand the greater effect of gravity. If you sat in a chair for 12 hours, you wouldn't be able to stand normally without wobbling your first few steps.
2) No. Undeveloped muscles as explained in #1. If anything, you'd jump higher when you were back in the anti-gravity chamber for obvious reasons.
3) Yes. You'd be a little taller from not having the effects of gravity on your spine. This is already evident from people being slightly taller in the morning than they are when they hit the hay.


Edit: mistook the idea of "increased gravity" with "decreased".

Not sure how you came up with the idea of iron in your blood poking through your veins and killing you in a glorious iron riot within your blood stream... unless the anti-gravity facility used a giant magnet which sucks iron out of you until you look like a human blood sprinkler. If the effects of gravity on your entire body is small, the effect of gravity on those iron molecules are proportionally less as well and vice-versa.

Natural selection is less about adaptation and more about the ability to procreate. While it is true that if one is more "adapted" to an environment, one is more likely to successful procreate, however favorable traits that one learns or "adapted" during one's lifetime does not get passed onto their offspring. For instance, if you work out and become athletic, you may be more fit to survive but your child will not gain the athletic abilities. Those traits of athleticism are "acquired" through randomization in the gene pool (Darwin's theory of evolution); favorable traits (such as athleticism) allow the organism to survive and pass on those traits.

I think he got that iron idea from X-Men :f6:

I don't think you read his post at all. He's talking about a chamber that increases gravity, not decreases it.

It would take more than a week to acclimatize, but I think it would work if it was like 1 m/s/s more every month, maybe.

I think after this experiment the results would definately be an increased reaction time, above all else. If you had to dodge knives travelling with a force of 50N/KG, I would say that you would have pretty fast reflexes.

When calculating for gravity, mass is disregarded (negligible) when it is over a relatively small distance change in mass. For example, the acceleration due to gravity on the Earth's surface is -9.81 m/s^2 for most objects at sea level. If you drop a large object such as a person, and a small object such as a bullet at the same time off a tower, both objects should hit the ground at the same time (the time is negligible).

However, the true equation for describing gravitational force that is used for large objects over large distances is G(m1*m2)/d^2, where m is mass and d is distance. In this case, people with a larger mass would fall faster due to experiencing stronger gravitational force, so you would fall faster than those bullets you're dropping on the floor. Imagine a bottle with various liquids in a normal gravity environment. The densest liquids will end up on the bottom and and the least on the top.

Since you stated the opposite, that the bullets fall faster in your hypothetical situation, it makes more sense to describe the "gravity" in your hypothetical situation more as an anti-gravity (repulsive) factor coming from the ceiling that causes smaller objects to move away faster from the ground than larger ones. When considering liquids in your hypothetical situation, the least densest liquid will end up on the bottom, and the densest liquid will end up on the top. Assuming that you're already on the ground from being subjected to the gravity for a long time, iron will be unlikely to be the first to break out of your bloodstream since it is denser than other compounds that are in your body.

Anyways, smaller things falling faster is not the way gravity works. Also, gravity change is negligible over a reasonably massive planet, so if people were to ever travel to another planet or mass other than the Earth, they're just going to adapt one time. I don't see why scientists should need to experiment for this by placing a subject in an ever changing (anti)gravitational room.

Right idea, but wrong reason. Gravitational acceleration is the same for all objects because while the force applied is proportional to an object's mass, the amount of force required to produce a certain acceleration is also proportional to mass.

0.01 kg bullet => 0.098 N gravitational force => 9.8 m/s^2 acceleration
100 kg person => 980 N gravitational force => 9.8 m/s^2 acceleration.

He's talking about a hypothetical chamber with increased gravitational acceleration, whether from being on a planetary body with more mass, less radius, or artificial "gravity" caused by rotation. In this case, any object, bullet, person, whatever, would fall faster.

Actually making such a chamber wouldn't be too difficult to do. It wouldn't require any advanced technology, just a rotating circular hallway with a slanted floor.

I interpreted this as "smaller things drop faster than larger ones", which would mean that somehow, acceleration due to gravity is not constant as it is in the real world. Actually, Random_Overlord's system would make more sense if the force applied is constant, because otherwise bullets cannot drop faster than people if they have less mass.

How would this increase gravitational force on objects floating in the air? How would this increase gravitational force in the system Random_Overlord described?

I interpreted it as a bad description of how objects would behave under increased gravity.

You're right, any object floating in the air prior to the rotation would not experience increased gravity. However, any object thrown into the air from the rotating chamber would have outward momentum that would cause it to "fall" to the floor at what appears to be an accelerating rate. I'm fairly sure of this.

To increase the force gradually over time, just increase the speed of rotation and the angle of the floor. Would be tricky, but not impossible next to other methods of simulating gravity.

He was just saying ANYTHING dropped on your foot would hurt like a bullet shooting you in the foot.

Then how would iron weigh down on your veins and cause you to hemorrhage?

I wouldn't take so much into the "you have crap in your veins and it'll explode you" arguement. I think the harder, more important thing would be something along the lines of your heart needing to work much harder to pump the blood around your body, correct?
