Humans in 10x Gravity

posted on November 24th, 2011, 9:42 pm

as we have never seen one with an atmosphere like earth, we just asume it will be there if there is life other then on earth just because of the infinite posibilities.

if there actualy would have been formed less gasses somewhere there would be less gasses to trap and yes vulcanic activity would prevent this already but im just saying we don't know the posibilities

It would shove your spine into your brain and the ridiculously dense atmosphere of such a planet would splat your blood out like squeezing a sponge. 

Under such extreme conditions even water would be solid because the massive gravity presses the water molecules so tight together that they act as a solid. 

If by some miracle you would find yourself being a few seconds alive and next to a canyon you would see down that canyon the oxygen in a semi-fluid fog-like state oozing throughout the canyon itself.

I will anwser the above in the spirit that because of the increased gravity, the air pressure is also bigger 10-fold and the temperature is the same as on Earth, since beef did as well.

I do not know if the conditions would indeed squeeze your blood out of your body, because Im just not that familiar with the capabilities of the human body; though it seems to me that that anwser has a way too "sci-fi" feel to it 
Consider that we are mostly made of water and solid matter - both of which are practically uncompressible under these conditions. I'd imagine the huge increase in the air-pressure would do bad things to our airways though. Nevertheless I still belive the main macroscopic problems with our body would be in the circulation and in the breathing compartment in addition to the problems we would experiance on the molecular level, which Dominus mentioned earlier (which I'll not dwell on, since I'm not familiar with the maximum tolerance of g-forces and pressure the cell can endure. I have to say though, I'm not quite as certain as Dominus that there would be such drastic effects on the cell - consider the effect of gravity in the microscopic world and the fact that there are some bacteria that hitchike on a meteor and can possibly survive the impact (one of the theories of the beginning of life)).

It also seems more logical to me that blood would seep out of our bodies, if we would experiance decreased air-pressure, an extreme example would be the vacuum of space. You see, water is actually quite sensitive to the decrease of pressure - it's volume goes up, while density goes down, respectivly. That would actually cause our blood and all other bodily fluids to firstly increase in volume and thus break the cell membranes and eventually evaporate out of our bodies completely.

About the water turning to ice due to increase in gravity, with the temperature constant part. Actually that's not possible with water. If you look at the phase diagram for water you see, that if the temperature is constant at ~ 20 °C, no matter how much one increases pressure, water will not solidify.

The part about oxygen I'd guess is also untrue, but I was not able to find a phase diagram to prove my point. If you consider though, that you need, at 1 atm, to chill the oxygen down to -220 °C to liquify it, I very much doubt that 10 atm would do it at 20 °C.

Errrr no were talking gravity here, how is a force pulling DOWN going to pull your spine through your brain....


Anyway i do think you guys are underestimating a humans ability to adapt, 10g maybe too much when you think about it now with our body's current ability's but you see some amazing things on tv and the internet about human adaption like the monkey man whos bones have adapted to be very monkey like giving him the ability to swing around on his finger tips as monkeys can with all that weight pressed on them.

With a gradual adaption over generations that extra weight would be compensated by muscle, stronger bones, our muscle fibers to become even more dense to rival that of some animals on this planet so carrying that extra weight would be no different to the way we are now, our bodys have adapted to this planets level of gravity and we are comfortable, i think if gravity were slowly increased we would eventually adapt.

Obviously people with genetic defects, heart problems ect would die out during that time but the strong would survive and adapt.

well, we do also not adapt to radiation, although we have plenty of it around. Or we do also not adapt to decapitation.
There are a lot of things you can't adapt to, as they destroy our system. Either on an atomic level like radiation or extreme gravity or on a well visible level like, well, losing your head.

Besides, in order to kick of evolution, you require generations which requires children to be born in the first place

No, all would die, the structural integrity of calcium constructs (bone) is not nearly strong to support such gravity, by the time gravity reaches 7g's we would need carbon fibre bones and muscles that would support 10 times our own weight. That is 10 time our weight @7g's because we still need muscle power to lift things, @10g's we would propably need 18 times greater strength if were to be able to operate at all in such an environment.

You have to understand that it is not just gravity itself you are dealing with but also the much denser atmosphere being pushed down by all this intense force. 10x gravity might as well be up to 25x greater air pressure.

Thats all on a completely different level to gravity, gravity does not destroy our cells, radiation does.

Gravity is an environmental element and our body's have adapted to what earths gravity is now and a bit more to give us the ability to walk,run,jump ect without any problem, if you were to work out more you gain more muscle mass we gain the ability to carry more weight, to jump higher.

Why is it so hard to think that over time our body's would get stronger and our muscle mass may evolve to be more dense so that our maximum capacity for strength is much much higher than it is now.

Our heart could evolve to become stronger and there by get blood to all parts of our body as it does now... its really not that hard to imagine. Wether is possible to adapt to such an extreme gravity like 10g's is actually possible i don't know but we could adapt over a long time with the gradual rise of gravity, of that i have no doubt.

You cannot adapt to decapitation because this isn't a constant effect on the body that evolution can fix, its death, how can you pass on this genetic info onto your children after you have been beheaded

No, all would die, the structural integrity of calcium constructs (bone) is not nearly strong to support such gravity,

You are still thinking of what our body's are currently capable of which means you are not bothering to read my posts and therefor i will not bother to read yours fully.

MrXT:
Perhaps we might be able to adapt, IF the gravity would increase very very slowly over a huge time period. The only problem is that, the original post was asking if we could go and survive on a planet with 10 x the gravity. Unfortunally that is not a gradual increase, but a very sudden and deadly one. There is no way someone would survive that - and if you cant survive, the future generations cannot adapt to it either...

So while you may have a point in that the human ability to adapt to different situations is amazing, there are such extreme conditions we just cannot survive and therefore not adapt to. You see, the key variable is the time in which the change would happen - and we're talking about immediate increase to 10 g's; that we cannot possible survive.

Well in that case my statement applies.

Now some of you have asked how your spine would be shoved into your brain? Well its skin resilience. As the rest of your body is pulled down by the immense gravity, the spine is literally stripped off the tissue its held on to. As the body begins to collapse on all the mass it is the skull that shoved unto the spine like putting a head on the spike!

YUMMY!

Im sorry for the graphic descriptions I provided but I thought I would give you a realistic picture of what would happen to you. Its simply a calculation of mass incorporative biology of various tissues in a human body and gravitational phisics.

@ Beef: Oh please  The imagination is running wild huh

No its a fully legitimate and scientific procedure:

1)Proceed under the assumption that the gravity would suddenly increase from 1g to 10g,
2)Calculate the the new atmospheric pressure using the volume of earth's atmosphere as a template,
3)Calculate the tensile strength of the tissue that holds the body to the spine,
4)Estimate that the body will collapse straight down,
5)Under the previous estimation concede that the spine would be in an upwards position as it hits the ground,
6)Basic rule of compression states that "softer" tissue allways yields to the "harder" tissue, which means that the skull will be breached as the skin pulls down the rest of the body.

It really is just putting some high school stuff from biology, math and physics together. the model also suggests that the last thing you will se is your bones sticking out from your knees before you become the puddle on the ground.

LMAO

I won't bother anymore mate. Believe what you think and I'll believe what I think and let's agree to disagree

Ye an if you read all my posts you would see i already addressed exacy what the topic was about and gave info on how we might be able to exist in that gravity after long periods of evolution.

Everyone including my self have already stated is impoosible to survive more than few mins in that kind of gravity if you were just exposed to it, my theory was just an attemp to keep a discussion going.

Should have known that's quite impossible with people here because you don't but keep posting.
