In space, it means that floating in space is a latent role, and it can represent some livelihood travel in space.
-
What do they mean in space? You should read some introductions on the Internet about this, some information about this space.
-
In this case, you can go to that degree and search it to see what it means in space, or you can also look up the relevant knowledge about space to see.
-
In this dish, space means the area of light.

Space refers to the cosmic space outside the Earth's atmosphere, the entire space outside the atmospheric space.
Space: Cosmic space beyond the Earth's atmosphere, the whole of space beyond atmospheric space. Physicists divide the atmosphere into 5 layers:
Troposphere (sea level to 10 km), stratosphere (10 40 km), mesosphere (40 80 km), thermosphere (ionosphere, 80 370 km) and outer atmosphere (ionosphere, above 370 km). About 3.4 percent of the atmosphere above the Earth is in the troposphere and 97 per cent below the stratosphere, the outer edge of which is the maximum limit for aircraft to fly with air support. Some high-altitude rockets can enter the middle layer.
The lowest orbit of an artificial satellite is within a thermolayer, and its air density is 1% of the Earth's surface. Air continues to exist at altitudes of 10,000 km, and there are still airborne particles even at altitudes of 100,000 km. From a strictly scientific point of view, there is no clear boundary between airspace and outer space, but rather a gradual convergence.
The Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space noted that it was not yet possible to come up with precise and lasting scientific criteria for delineating outer space and airspace. In recent years, there has been a trend towards the minimum altitude of satellites off the ground (100,110) kilometres as the minimum limit for outer space.

Space Space refers to the universe outside the Earth's atmosphere, the entire space beyond the atmospheric space. Physicists divide the atmosphere into 5 layers:
Troposphere (sea level to 9 km), stratosphere (9 45 km), mesosphere (45 80 km), thermosphere (ionosphere, 80 400 km) and outer atmosphere (ionosphere).

It's very simple, that is, you don't have a pen, you can't write brilliantly, it's obviously a pot of Longjing that insists on asking you to give it into boiled water.

Personally, I think it's saying that what you write in your article is not very realistic, and there is too little ink and not enough detail in the description of people and things. The most important thing in the article is the truth, it is best to write what you have personally experienced, if it is a fairy tale, science fiction or the like, you should also write the details. Moreover, if it is to express your personal opinion, don't talk about it endlessly, it will seem empty.

Gravitational acceleration.
A g means that your current acceleration is gravitational acceleration, and the force you are subjected to is the gravitational force of the earth itself; 2 g is twice the acceleration. Force f=mg, acceleration a=f m, so a few g's means how many times the acceleration of you and the entire spacecraft is how many times the acceleration is due to gravity. Astronautics, the mass is certain, the greater the thrust provided by the high-power engine, the greater the acceleration, the astronaut has inertia, so the spacecraft forward, the astronaut is equivalent to backward, the spacecraft gives the astronaut a mile, so that the astronaut accelerates forward to the same speed as himself, the greater the propulsion power, the faster the spacecraft accelerates, the faster the astronaut will accelerate, f=ma, it can be known that the astronaut mass remains the same, the greater the acceleration, the greater the force on the astronaut.
When the force is too great, the human body will be harmed. Just like "Three-Body Problem 3 - Death and Eternal", it is forcibly accelerated, and does not enter the inertial medium with deep-sea liquid as the main body, and the person is directly slapped on the wall like pressing a meatloaf, and the blood spreads on the wall in a divergent manner. Another example is in Star Trek 2 - Darkness Unbounded, where the Enterprise is gravitationally pulled by Earth.
Grab, accelerate towards the ground, and unprepared people will stumble over the wall or even get sucked into the wall. (These are a bit exaggerated, the film does not take into account weightlessness in outer space, and is captured by gravity at a long distance, the acceleration is not large, and the characters are a bit exaggerated on the wall).
Astronauts will sit in a place where they can do circular motions when they are training.
As the speed of rotation increases, the greater the force on the astronaut, where centrifugal force is used.
In place of gravity, astronauts are required to withstand about 8 g. Centrifugal force or centripetal acceleration, a=mv radius r
-
A capital g denotes the gravitational constant, and the accepted result is the Cavendish determination of the g-value, which is, and the latest recommended criterion is g=. Usually take g=. Sometimes it also indicates gravitational g.
Whereas, lowercase g indicates gravitational acceleration, which is the amount of change in velocity caused by gravity per unit of time.

Understand, what does it mean that the comparison is all space? I really haven't heard of the word I'm talking about it, and I want to know about him too.

Honorable astronomers, and convenient for people to study them.

"The four directions are called the universe, and the universe has been called the universe throughout the ages. ”
In other words, the ancients believed that "Yu" refers to the infinite space around us, and "Zhou" refers to infinite time throughout the ages. This is very close to what the word universe means now.
-
The universe means infinity, infinity in ancient texts.
-
The upper and lower quadrangles are said to be universe, which means that infinite space is universe.
Throughout the ages, it is said that there is infinite time for the universe.
The universe represents the entire four-dimensional universe.
Washing hair in space is completely different from washing hair on Earth, astronauts use shampoo caps containing shampoo to wash their hair, and they can wash their hair by putting the hat on and rubbing it. Our most basic behaviors such as going to the toilet, bathing, and sleeping on earth are very different from those in space, which shows that living in space is not an easy thing. >>>More
The solar system orbits around an imaginary black hole of the Milky Way. >>>More
Weightlessness in space comes from the space shuttle.
and centrifugal force of the space station's movement in orbit. >>>More
Density is an inherent property of an object, which does not change with changes in the environment, that is, the density of an object does not change in space.
In space, the reason why astronauts can't shed tears is because there is no gravity in space, he is not like the earth we live in, the earth has gravity, for example, ripe apples will fall to the ground, and our tears can also fall on the ground. At the same time, we also know that astronauts will be in a state of weightlessness when they go to space, which means that astronauts will have great difficulties in every step in space, and other accidents may occur. <> >>>More
