KEYWORDS migrating extraterrestrial radiation
Growing knowledge: When life on earth is on the brink of extinction, the best way to survive is to look elsewhere to build a habitat
If a human base can be established on Mars, the moon or other planets, it will be crucial to the continuation of human civilization. How long humans can survive depends to some extent on ourselves.
Wanting to evacuate the earth safely and be able to move to aliens smoothly is easier said than done, some people will sacrifice for it, but it will also save more people
Facing the earth, the choice this time is life and death, escape or destruction"
After watching: every major decision crisis moment must have many people's struggle contribution and even pay the price of life for it!
Those people become heroes for all of us
It reminds me that mankind has faced several historical crises, and the reason why they can turn the corner and survive the crisis is the sacrifice of countless martyrs!
Increased knowledge: "Everything is in motion The Earth is not only spinning, it is orbiting in space at nearly 110,000 kilometers per hour and Mars is traveling at more than 80,000 kilometers per hour.
So going to Mars is like shooting a bullet from a gun to hit another flying bullet."
After watching: I didn't expect to log in to an alien planet, in addition to being able to fly to the sky above this planet, but also to log in to this planet is also faced with huge technical difficulties!
Increased knowledge: "We've sent probes to Mars, Jupiter, and Saturn, but the probes are just machines. It's as hard as going to the sky to get humans there safely"
After watching: New knowledge of spaceflight Originally, I thought that after the successful landing of human beings on the moon, the technical difficulties have been overcome and the other planets can be accessed by analogy. It seems that I am really a naive "foreign disk"!
Growing knowledge: "Man couldn't fly back in 1902 but the Wright brothers made it a reality
Walking on the moon before the summer of 1969 is a nonsense
Until 12 astronauts left a giant leap for humanity on the lunar surface
We can build a space station to reach the moon and we will eventually land on Mars"
After watching: I have understood two major events of human flight before, but I don't know exactly when it happened
Growing knowledge: "Mars is known as a habitable zone planet with a hot and cold climate similar to Earth. Moving to Mars is our next best option until a more suitable planet is found"
After watching: I read the news before that scientists found that there was water on Mars, maybe there was life and there may even be highly intelligent creatures!
The thought-provoking quote in the film: "Even if we have the technology to fly away from Earth and travel into the universe, will we have enough physical skills to withstand it all?
Nothing in the world is eternal. The same is true for the earth. If human civilization wants to inherit longer than the earth, it needs to find another habitat.
If we really want to escape the earth, what we give up is not just a place to stand, but a shared home that breeds colorful species
It is a powerful planet lit by the light of life
We are the earth's earth and ours, if we really want to say goodbye, what should we choose?"
Growing knowledge: "Bacteria have the ability to penetrate every
Limulus is one of the oldest animals on earth
It was 200 million years earlier than the birth of dinosaurs. Not only that, it has made great contributions to human spaceflight.
The immune system of the horseshoe crab is ancient and primitive, but it is incomparably valuable. Its blood contains hemocyanin. When the cells in these blood come into contact with bacteria, they immediately release enzymes. These enzymes can even detect only parts in a billion. a bacteria
A drop of horseshoe crab blood is enough to detect bacterial contamination.”
After watching: The creatures on the earth are really rich and colorful, providing many vital help for human beings. The bodies of some creatures provide us with energy and nutrients for our bodies. Some creatures also have great medicinal value.
Now I have added knowledge that the blood of some creatures has also made important contributions to human spaceflight!
Growing knowledge: Bacterial cells in the human body There are more bacterial cells in the human body than human cells in number
Most species on Earth depend on microbiomes to survive"
After watching: I didn't expect that the human body is not full of cells, but the number of bacterial cells is full of human cells!
I only knew that the probiotics in the human body did not think that the microbiome is so important!
Increased knowledge: "Whales and humans are strikingly similar. Although we walk on land and they swim in the ocean, biological mechanisms make the same annotations for different life forms.
Blue whales are good at breathing, and it only takes a second or two to displace more than a car
The microscopic world of bacteria exists outside our body and is rooted in our body.”
After watching, increase new knowledge
Growing knowledge: The earth pulls us towards the ground with a tremendous force we call the acceleration of gravity The earth pulls us
But we are the only species that have found a way to escape gravity
The process of weightlessness in the space station is full of fun, food will be placed in the air, and countless somersaults
But in fact, the human body needs gravity to rely on gravity so that we can distinguish the weight from the body when sitting up and down, the weight from the arm when raising the hand, these constantly remind me of the difference between up and down, and after weightlessness, it all disappears, which will bring discomfort to the body and cause vomiting.”
After watching: I never thought that astronauts would endure such great discomfort, pressure and huge physiological reactions in the space station. Only after watching the film did I realize that traveling in space has to endure very great physical and psychological discomfort!
Increased knowledge: "When you are in the earth's gravity, the fluid in your body can follow the trend. When you are in space, the fluid will flow backwards. It is like standing on your head for three hours"
After watching: pay tribute to human astronauts and astronauts!
Growing knowledge: "Gravity determines the size of our heart and the layout of our cardiovascular system
The entire structure of the human body, whether it is skeletal structure or muscle strength, is shaped by the gravity of the earth.”
After watching: Another new knowledge Gravity not only allows us to walk safely on the earth, standing, sitting, and lying
It also shapes our entire human anatomy!
Earth's gravity is very important to us!
Growing Knowledge: Muscles and Bones Weakening If Gravity Loses
In the space capsule astronauts need to practice a lot of lifting and pulling fitness equipment
Including binding your body with a stretchy material to simulate gravity
But even the most advanced equipment can't stop astronauts from losing bone density and bone degeneration
The astronauts we admire are sometimes dizzy and sometimes nauseous.”
After watching: Once again, I pay tribute to those astronauts who have made outstanding contributions to the cause of human aerospace and aviation exploration. It is their heroic dedication to human aerospace that can develop and grow step by step. When the earth is no longer suitable for human habitation, we have technology. How to escape the earth and find a new home
Growing knowledge: "We are part of the earth and the influence of the earth on us is deep in our bones"
Impression: It reminds me that the living habits of family members will affect each other so that there will be more or less similar or the same living habits among family members
And the earth is the common home of human beings, which means that the living habits and living habits developed by human beings living in a "super family" must have a far-reaching and deep-rooted influence!
Strengthening knowledge: The earth gives us air and water energy as a comfortable and safe space to guard us
And can we find another second home where we can live comfortably?
Because the earth has the protection of the atmosphere, the deadly cosmic radiation can be transformed. This transformation also avoids direct radiation and damage to all things.”
Increased knowledge: "In the vast sea of stars, every time a supernova falls in a huge explosion, a huge amount of energy is released
Cosmic rays travel through the interstellar space at the speed of light, which is 300,000 kilometers per second, and these tachyons are so fast that they can reach Earth from Pluto in just five hours without being detected by the naked eye.”
After watching: "The speed of light in the picture is very beautiful!"
Increased knowledge: "If you were above the Earth's atmosphere these radiation particles would pass right through the body
Some cosmic rays also penetrate your optic nerve. The optic nerve structure of the human body presents the radiation as a light. This is actually radiation that travels through the brain.
After experiencing such a bombardment of radiation, it will not only increase the risk of cancer, but also may suffer from radiation sickness, which may cause genetic mutations.”
After watching: I realize that human beings want to move to other planets, and space navigation alone faces great dangers, hindering the universe and will not let us escape the earth easily!
Increased knowledge: changes after radiation are not limited to behavior Some creatures also change their appearance, most notably fireflies
The front of the common firefly looks like wearing an African tribal mask. It has two eyes, a nose and a chin. It is very symmetrical.
Fireflies with different color patterns appear in high radiation areas
The consequences of radiation are far more serious than changes in appearance, and genetic mutations can kill people.”
Afterthought: It seems that there are still many difficulties to be overcome for human beings to escape from the earth and move to aliens! There is still a lot of science and technology to break through!
I used to mistakenly think that as long as the energy limit of the aircraft is overcome, it is possible to emigrate to aliens!
This documentary made me learn a lot of new knowledge and got a lot of inspiration
Growing knowledge: "What was even more surprising at Chernobyl was the discovery that some species had adapted to mutated bacteria showing increasing resistance to radiation
If we can better understand the immune mechanism of these microorganisms, it will play a decisive role in the field of human radiation protection."
After watching: Organisms will have the ability to adapt to the environment. We humans also rely on the ability to adapt to the environment to survive and thrive!
If the research is successful, it will be another far-reaching and significant contribution of microorganisms to human beings.
Increased knowledge: "The biggest challenge of space travel is actually not related to technology, but human beings are fragile, unable to experience the four seasons, unable to see the blue sky, all eyes full of black or red volcanic rocks
The real danger to Mars is not an external cause like gravity, but a sense of alienation from the inside out
This stress not only affects my mood but also my performance.”
After watching: When we arrive on the earth, there is no way for human beings to live, and we can only adapt to the new environment. Fortunately, this point is that human beings have been constantly adapted during the process of evolution.
Growing knowledge: "You're a pioneer. All you can bring is what you have. The rest can only be self-reliant. Thankfully, self-reliance is the very essence of human existence.
We've taken a critical first step by starting to use simulated Martian soil to study how to build a habitable habitat outside of Earth."
After watching: It turns out that the simulation of earth-building on Mars is really planned!
Increased knowledge: "The Bajau people are very good at diving and can hold their breath for about three minutes at the bottom of the sea
The lenses of the Bajau people's eyes are adapted to the environment of the seabed from a young age. Their underwater vision is twice that of ordinary people.
In the short term humans can adapt to the environment In the long term humans can continue to evolve
Interstellar migration may bring unpredictable changes to human beings"
After watching: The survival environment of the fittest changes all things and changes people to make them evolve and evolve in order to adapt to the environment and adapt to the environment in order to survive. With stronger physical functions, we can live better
Conclusion: Once we leave earth, we are no longer earthlings, we will become aliens
One day we may risk leaving this earth but we will never give up this lighted planet
We always guard this earth and protect the common home of mankind."
After watching: No one wants to leave their hometown unless it is absolutely necessary, let alone leave the earth to be an alien immigrant
Therefore, we humans must cherish our blue planet and try our best to protect this planet.
