The Earth's relatively thick atmosphere, and its magnetic field, may be plausible
partial explanations. But the main reason is undoubtedly the fact that there's
no such thing as "space gas".
More ideas: Actually there is "space gas". For example it's part of the nebulae from which stars and planets form. However there's not much of it near the Earth now.
Of course comets give off dust and gas and we see "space dust" burning up in our atmosphere as meteors.
Probably very small amounts of gas do enter our atmosphere.
Also, there's the "solar wind" which is a gas plasma.
Overall though, I agree that there's not really any significant amount of "space gas" in the vicinity of Earth.
Because there is no air, water or living organisms to eat in space but there is on earth.
Yes because of gas.
You cant, the reason is because there is no gas or electricity in space or on any planets apart from ours.
For the same reason that our atmosphere on Earth does not escape into space - gravity.
You cant land on a gas giant But probes have gone "inside" gas giants
no
You cant a jet would not work in space.
No, coz if it does, it cant live on Earth, it can breath Space air
gravity keeps the giants planet's gasas from escaping
The atmosphere is held in place by gravity. Other things being equal, the more massive the planet, the harder it is for a gas molecule to escape into space.
No, they cant if it is a predatory missile or the smaller ones can't but nuclear ones can go into space and even circle the whole earth.
Yes, gas can exist in space. The interstellar medium, which fills the vast majority of space, consists of gas and dust particles. Stars are also made up of gases like hydrogen and helium. However, since space is a vacuum, these gas particles are very spread out compared to the atmosphere on Earth.
