In a World Without Gravity
In a world without gravity, one would be weightless, but always nauseous. Because of this, it would be very difficult to complete a lot of your daily activities without throwing up.
If you tried to eat something while you and your food are floating around, you will probably have a lot of trouble trying to hold your food down. In 0-g, life would be very hard. Roller coasters are a perfect example of this. I do not do well on roller coasters. I get sick when I encounter zero gravity for that split second on rides with loop-dee-loops and the like. This is how I know I would really suck at surviving if there was no gravity.
Not only would I be constantly puking, but I wouldn’t be able read or really even enjoy doing anything except floating around trying not to dry heave. So, I wonder how someone, mainly me because I do not have a strong stomach, would merely perform the act of drinking a glass of water and thinking at the same time in a world where everything floats. Without the force of gravity acting on all objects, there is nothing keeping us attached to the earth. We would simply float away from the earth unless we nail out toes to our floorboards, and our entire house to the earth’s crust. So, drinking water…this would not go very well for me. Not only would the water not be forced to stay in its proper area of residency, the cup, but it would be poured on my face if ever I tried to drink it, and that is most certainly NOT WHERE IT BELONGS.
However, since the only force acting on the cup is the earth’s, pushing everything away from its core, the water probably was already floating around in space somewhere. This would make for a very, VERY thirsty Alex, not to mention the rest of the world. Unless you had stocked up on bottled water prior to the sudden change in the laws of the world, you would be dead. Thinking during splashing water all over yourself, or trying to catch it as it pins itself to your ceiling, just as you are doing because of the lack of gravity, would probably present a slight problem. As if you weren’t already nauseous as could be, suffering from extreme thirst and boredom while you lie in wait on your ceiling for something interesting to happen like being crushed by that bookcase over there that has been slowly creeping closer with each passing second, you would also need to be able to think. While floating around on earth shouldn’t give you any more of a headache than when you lie down, I have a feeling that I would get them anyway.
However, in space, 0-g, your blood would be floating free throughout your body, just as you do so, subject only to those forces placed on it by your own circulatory system. Your blood would have no tendency to pool in any particular part of your body, meaning no headaches. But with everything floating around, I can’t help but think that all that free blood must make you kind of floppy. Without gravity, multitasking would probably be even more difficult than it is in a world with gravitational forces. If I tried drinking my water, while translating our national anthem into Arabic, WHILE I try to bike on one of those stationary exercise bikes, I would be very sad. Not only would I be nauseous and EXTREMELY THIRSTY, causing me to get a headache, but I would be floating away from my excise bike, while trying to stay on it, that giving me exercise within itself.
I can’t even imagine how long our species would survive before we either all starved to death or tried to open a window for fresh air and then floated into our atmosphere and died from lack of oxygen. I don’t think that we would live very long at all, and drinking a glass of water would be so terribly difficult that it would make living very complicated.
