If space is a vacuum then what stops it sucking all the air away from planet Earth?
This is a good question. It really does seem that that is what should happen, doesn't it? The reason we come to this conclusion is because we live our entire lives within an atmosphere, and for us a vacuum is a strange thing-- even exotic. The truth is that 'vacuum' or near-vacuum is by far the most common state throughout the universe. Do this in your mind: Imagine a planet the size of earth, and the planet is floating freeling in the middle of intergalactic space. It has no atmosphere at all. Over billions of years, gas molecules drift in space close to the planet. Gas molecules are matter, and therefore they have and they respond to gravity. Over time, these gas molecules are pulled down to the planet by gravity. Vacuum is the normal state everywhere, but the planet's gravity attracts gases and the layer of gas becomes more and more dense. If the planet is geologically active, volcanic eruptions may bring gases to the surface as well, and these gases are held down by gravity. Gases could come from other sources too, like comets and other objects that crash in.

When solar energy travels from the sun through a vacuum of space to the earth?
When solar energy travels from the sun through the vacuum of space to Earth, it does so in the form of electromagnetic radiation, primarily visible light and infrared radiation. This energy is what fuels various natural processes on Earth, such as photosynthesis and warming the planet.
Can heat radiation travel through a vacuum?
Yes, heat radiation can travel through a vacuum because it does not require a medium for transfer like conduction or convection. This is why the Sun's heat can reach the Earth through the vacuum of space.
What is the difference between a vacuum cleaner and a vacuum?
A vacuum cleaner is a machine used to clean floors by sucking up dirt and debris, while a vacuum refers to a space devoid of matter or air.
Why doesn't earths atmosphere get sucked into the vacuum of space?
Earth's gravity keeps our atmosphere from being pulled into space. The force of gravity pulls the gases in the atmosphere towards the Earth's surface, preventing them from escaping into the vacuum of space. Additionally, the atmosphere is held in place by the Earth's magnetic field.
How does a satellites move in space when its vacuum?
well space is like a vacuum you cant escape it and sound wave do not travel in space but space isn't literally a vacuum so they move by rockets and the gravity of earth
What is the third planet in space?
earth
How can we make an artificial vacuum on earth?
Creating a complete artificial vacuum on Earth is challenging due to the planet's atmospheric pressure. One way to approximate a vacuum is by using vacuum chambers that remove as much air as possible. These chambers can be used in scientific experiments and industrial processes to simulate low-pressure environments.
Does Electromagnetic from the sun travels to earth in the vacuum of space?
Yes, it does.
Can you apply vacuum from space to earth?
Why would you want to take "nothing" from space when there is plenty of "nothing" right here on Earth.
Is air between planets?
No, there is no air or atmosphere in the vast empty space between planets in our solar system. Space is a vacuum, meaning it is empty of gases and molecules. The thin atmosphere around planets like Earth fades into space as you move away from the planet.
Why cant sound travel from planet to planet?
Because space is a Vacuum, there are not enough gas molecules around to transfer the sound waves.
How much vacuum is present in space?
Space is not completely empty, but it is very close to a vacuum. The pressure in space is extremely low, with only a few particles per cubic meter. This makes space a very good vacuum compared to conditions on Earth.
