Interesting changes in zero gravity environment
The universe contains many mysteries that we humans have yet to find and cannot explain. Even what is considered to be the truth under the Earth, in a non-gravitational environment in space, it is the exact opposite. Let's explore the amazing transformations of things in space through the article below.
Heartburn
Under normal conditions, under the influence of gravity, liquids often sink into your stomach and the air is pushed upward. However, for astronauts working in a zero gravity environment this is completely different. Imagine that the liquid in their stomachs cannot sink under and cause a phenomenon called 'wet burdens'.
Because of this problem, the International Space Station did not store carbonated drinks at all. If it is, these drinks cannot push the gas up on the Earth as well. When drinking carbonated drinks, water and gas are often separated in the stomach, and lead to heartburn. To overcome this, carbonated beverage manufacturers, in particular Coke / Pepsi, have improved and introduced drinks suitable for zero gravity environments, making astronauts feel Tastes as in normal environments.
Speed
Small hole on solar panel
In space, fragments move at such a fast speed that our brains are hard to recognize. Around the Earth there are millions of small debris and they move at an amazing speed: 35,500km / h. At such a high speed, we will not be able to see the object coming or more precisely the brain does not control the body in time.
In the universe, debris of different sizes can completely collide with spacecraft or other artificial objects. Even small pieces of a few millimeters of diameter can cause holes, like bullets with great velocity. However, we are not too worried because NASA can predict such collisions and the Space Station's protective layer is built to withstand such effects.
Static electricity
Static electricity can cause quite interesting phenomena. For example, make water droplets spin around an electrostatic needle or feel electrocuted when touching wool blankets. Electrostatic forces affect other objects, pulling them towards it as gravity acts on planets. However in space, electrostatic force is stronger than we imagined.
Scientists are studying to create a static electric tractor array, capable of clearing garbage in space. Currently, more and more waste is flying around Earth's orbit and this beam can absorb them and throw them into space.
Eye sight
About 20% of astronauts used to live on ISS International Space Station saying that their eyesight was reduced when returning to Earth. And so far, scientists have not had an accurate answer to this. We often assume that, because in low-gravity environments have released body fluids on the skull and increased cranial pressure. But recent evidence suggests that the cause may be related to polymorphism. (polymorphisms). It is an enzyme that affects the body's processing of nutrients.
Surface tension
Surface tension in space
We often do not pay attention to the surface tension on the Earth because of gravity. However, when in a zero gravity environment, the surface tension is much stronger.
Try taking a thin steel ring connected to a rod as a handle and dipping it into water. When you lift it horizontally, you will feel that the water surface is retained inside the ring, but then it will break. However, in a weightless environment, your bracelet will have a water film and it is very durable, like it has turned into a plastic. Scientists reasoned, because under normal conditions, under the influence of gravity, the surface tension is driven downward, causing the membrane to break down. In a gravityless environment, with no force downward, water is only responsible for maintaining the link. This link is quite stable, though strong shaking cannot break unless there is another object acting on it.
The exercise
People often think that astronauts' muscles are shrinking in space, so to deal with this problem, astronauts have to exercise more than ordinary people. Space is not a place for meek people, whereas they are well trained to avoid aging bone structure.
In fact, NASA pays great attention to regular exercise in space. Without this mode, astronauts are not only weaker when they return to Earth, but they also have a lot of muscle and muscle atrophy. Because in a weightless environment they have less walking or strong movement. More importantly, muscles can be recovered but bones are unlikely to fully recover.
Bacteria
Salmonella
In an experiment, scientists sent salmonella samples (bacteria that make food poisonous) into space and are seven times more dangerous when returned. This seems to be an unhappy news for astronauts' health, but it has helped scientists find a way to overcome this type of bacteria both in the universe and on Earth.
By studying the salmonella bacteria gene in low gravity environments, scientists determined that high concentrations of ions could completely inhibit bacteria . Further research can produce vaccines and treatments for salmonella poisoning.
