it seems strange that the vacume of space dosnt just suck out all the air,
this arose due to an answer to my previose question ,putting into my mind the thought we could use the vacume of space to transport stuff into space
ie vacume space travel ,like a big vacume cleaner tube that sucks up into the vacume of space ,but even if it could suck up objects it first would suck up our atmosphere ,yet why isnt it doing it allready ,vacume thus cant be that strong in space ,air aint that hard to suck ,figure that god stops the sucker if you get what im asking?

Gas, air, the atmosphere - it's made up of molecules of gas, each of which has mass. That mass is attracted to the Earth by gravity. Light as air is, it still has mass that it captured by Earth's gravity. When an asteroid comes along and smacks into the Earth, water vaper and air are throw far out into space, several hundreds of miles (the atmosphere is only about 100 miles high). However, it all comes back due to the force of gravity.

However, Earth's gravity is not strong enough to hold the lightest elements, hydrogen and helium. That is the reason Earth is a small rocky planet and not a gas giant like Jupiter or Saturn, or even the sun. Get big enough and you can attract even the lightest elements - which adds mass - which attracts more gas - which adds more mass - etc etc etc.

That's why your idea, unfortunately, won't work. Gravity.

No, it couldn't. No more than a tube dipped into water can suck out the water. You may say that a tube CAN suck out the water if there is a vacuum applied, but that is only true up to 33 feet. If you have a 34 tall pipe and put a vacuum pump on top, the water will rise to 33 feet and stop, leaving 1 foot of vacuum at the top. That makes a water barometer. The same thing happens with mercury in a regular mercury barometer, but the tube only has to be 33 millimeters high due to the high density of mercury. In a tube to space, the air would rise no higher inside the tube than it does outside.

Well, setting the "God" stuff off to the side, your question suggests that a vacuum sucks things, i.e., a pressure differential
exists between our atmosphere and the vacuum of space. Yes,
it does exist, and it exists because of gravity holding the mass
of our atmospohere to the much larger mass of the Earth.

Your sucking device would have to suck hard enough to overcome the Earth's gravity. So far, in about 4 billion years
nothing like that has happened...(Earth's age has been calculated
at close to 4 billion years.).

than that of the Earth's gravity

It's Vacuum General Relativity and it's only zero inches of vacuum except a black hole whitch is at a greater vacuum warp then general vacuum Relativity. And like the moon if the Earth stoped producing oxygen, putting pressure on the vacuum of space yes we would loose our bubble. And this is Why Einstein theory of General Relativity was wrong but he did not know.

No, for the same reason a tube stuck in the ocean doesn't suck the ocean dry. Another way to think of it is that the open sky is just a really wide tube, and making it smaller doesn't change it's effect.

It has already sucked out all that it can. Out atmosphere is the only thing that is left and it is safely held in by gravity. Anything that exceeds the boundaries of our gravity will most definatly drift into space.

There is no physical barrier between our atmosphere and space. It is gravity that holds it all together, so no, your plan would not work.

the vaccuum of space is not like a vaccuum cleaner,it is a different principal.
