10 Daily Things Happen in Space in a Strange Way
There is no similarity between what happens in Earth and what happens in space. Even if the event is one, the way it occurs becomes double; one for the earth and one for space. If I asked you, for example, about the boiling water, you would tell me how it happened on the floor in a pot inside your kitchen, but I bet you do not know how to boil water there in outer space! And this is somewhat self-evident! Here we get to know everyday things that happen in space in a strange way.
1. Torch in spherical space
On the ground, the flames rise. In space, moving outside its source in all directions, here's why:
The more we join the Earth's surface, the more the air molecules get, thanks to the gravity of the planet. On the contrary, the atmosphere becomes thinner and thinner and you move vertically, leading to a gradual decrease in pressure. It is enough to form a candle flame.
The difference in pressure causes an effect called natural convection. The higher the air temperature around the flame the more it expands to become less dense than the surrounding cold air. As the hot air molecules expand outward, the cold air particles are working to keep them away, Cold air drives more against the hot particles at the bottom of the flame and at its peak, the flame rises to the top where it faces less resistance, and when gravity is lacking and despite the expansion of hot air experiences it faces equal resistance in all directions and therefore moves spherically Outside its source.
2. Bacteria grow more ... and become more deadly
It showed thirty years of experience that the bacterial colonies are much faster grow in space. For example, the research found that the bacterium E. Common -kolay on Earth is growing twice as fast in space, in addition to that some bacteria become deadly, and the experiment was conducted in 2007 on growth showed Salmonella on the space shuttle Atlantis to the space environment changed expression of 167 genes from bacteria, also found studies conducted after the flight that these genetic changes have made salmonella more likely to cause disease in mice three times more than bacteria grown on the ground, and explains why scientists this that bey Leiria grow while in the place of zero gravity, that it gives them the opportunity and space to grow larger, where gravity seems to limit their growth in one way or another.
3. You can not burp in space
The absence of gravity means that the buoyancy law is also absent, so there is no reason to push the gases in the soft drinks out of the stomach, that is, the burping is the process of removing the gases from the abdomen does not exist, and the result is that drinking soft drinks can be very painful because of Retention of these gases in the digestive system.
4. The smell of flowers in different space
Flowers produce different aromatic compounds when they grow in space, and as a result, they give a different odor from those usually grown in the same flowers on the ground. In other words when cultivating flowers in space, researchers found that the aromatic compounds they produce differ from those produced by the same When the flowers are grown on the ground, so their odor is different, the reason seems to be that the volatile oils produced by the plants and which carry the fragrance are strongly influenced by environmental factors such as temperature, humidity and age of the flower and therefore it is not surprising that these oils will be affected With a little gravity as well.
5. Race multiplies into space
Gravity also plays a major role. As mentioned above, the lack of gravity also means the lack of convection. This means that the body loses an important means of cooling. The solution is to produce sweat to reduce its temperature. Space does not evaporate and does not fall off the body, but accumulates on the body continuously, so if you do not like the smell of sweat and the sense of wetness that accompanies you do not reserve your place in the next trip to space !!!
6. Eyes of astronauts crushed in space
The eyes of some of the pioneers become somewhat crushed, affecting their vision. The pressure is concentrated on the back of the eyeball. The eye's nerve is exposed to some abnormal curvature. The lack of gravity seems to make the fluid rise to the top. Of the human body including the head due to the abundance of fluids.
7. No blood pressure in space
Space has terrible effects on the human body. As a result, the body finds it difficult to maintain normal blood pressure, and the heart is unable to pump blood through the enlarged veins, which can lead to an effective reduction of blood pressure to zero , And who was killed.
8. Rapid cooling
On hot days, our bodies produce sweat for cooling. Evaporation of sweat from the surface of the skin consumes heat energy and causes cooling effect, but this effect is greatly exaggerated in outer space as the lack of moisture accelerates evaporative cooling, The body is at risk including fluids in the eyes, mouth and respiratory tract.
9. Choking by hypoxia
When exposed to vacuum space, the person will be completely deprived of oxygen, but not in the way that you may think, and this condition is known as hypoxia, what happens exactly?
Without compression pressure on the ground, oxygen begins to withdraw and escape from the blood stream. This makes the cardiovascular system useless and can not transport oxygen to the muscles and vital organs. The first signs of suffocation are the skin turning to blue.
10. Boil water in a large bubble
On the ground, the process of boiling the water creates thousands of small bubbles; but in space there is one huge bubble!
The fluid dynamics are so complex that physicists do not know for sure what will happen to boiled water in microgravity until the experiment was conducted in 1992 aboard the space shuttle.
After that, physicists decided to be one giant bubble due to the absence of convection and buoyancy law are two phenomena linked to gravity.
There is much to be learned from these experiments according to NASA Science News as they will help provide the spacecraft with more efficient cooling systems, and could one day be used to design power plants for space stations that use sunlight to cool the liquid to create the steam used to run Turbines for the production of electricity.
