The atmosphere is not contained inside a rubber tire LOL. Or maybe you mean it’s the air on the outside of the tire that supports the truck?

But does not a vacuum do just what you say space does not do? siphon off our atmosphere? Nature abhors a vacuum does it not?
The vacuum does not strip away our atmosphere because there is no suction to the vacuum of space -- there is no air pressure forcing things into the vacuum.
The gravity of the Earth holds the atmosphere in place. About three kilograms of hydrogen and 50 grams of helium (the two lightest gases) per second leak into space.

But wouldn't a gravity formed ball be perfectly round? Whereas a push of war formed sphere would be resistant, biased where it could be?
If it did not spin it would be round, but the spinning causes the center to “bulge”.

Planets are round because gravity pulls toward the center. They aren't perfectly round though. Planets have a greater diameter at the equator than at the poles because they spin around their axis.

THIS WAS COPIED HERE FROM BIBLE TOPICS

I would ask you one question...we can define the effects of gravity but what causes gravity?
_________________________________________________

Quantum physics proposed a theoretical particle called the graviton that controls gravity.
That brings us to our current understanding. Gravity still remains one of the biggest mysteries of physics and the biggest obstacle to a universal theory that describes the functions of every interaction in the universe accurately. If we could fully understand the mechanics behind it, new opportunities in aeronautics and other fields would appear.

There has always been an element in science of fiction when such things like dark matter in the universe (that cannot be detected) is presupposed to be real and volumes if not libraries of conjecture are written and fellowshiped, entire schools of thought dedicated to this, and awards given to "scholars" over something that has not even been proven to be true or exist.
Macro-evolution for example which by the admission of many who champion it isn't even a good theory... yet it is taught as fact in schools and in science documentaries and in the media at every half chance...
Graviton huh? Well we'll see.
Space is curved (which the scriptures supported all along with the description of its being unfurled like a tent canvass). And any body in space beyond X density and mass is curved (spherical) which the Bible also mentions in several places. Which the Bible describes as being suspended in nothingness... interesting for ancient writings eh?
What we call gravity is the push of war (opposite to tug of war) between space and that body of mass (beyond the size and weight of X).
Simply put, space pushes / compacts planets into spheres and the mass / density of the planet pushes against space the smaller less dense the planet the less tension (gravity) between the two. The greater the mass and density of the planet the greater the tension (gravity).
Should the Lord tarry and there be a space exploration future for mankind the problem of payload versus thrust will be solved by tipping the balance between the two bodies into a field of far less dense mass / density.
I have no idea how that will be accomplished. But some foresaw nuclear power by the evidence of the sun, and we have as much evidence of even greater power (singularities super massive singularities etc.). And IF man is ever capable of harnessing matter / antimatter power it will prove to be as significant as harnessing electricity or splitting the atom.
Bending gravity into zero gravity would then be no problem and would produce more results here on earth than we could imagine. Think of zero gravity elevators for example. Zero gravity transports (trucks, cars, trains, planes, forklifts, pallet jacks). Zero gravity surgery and diaper changing stations. You name it.
Think of the sports that would be invented in zero g.
All based on the same principles laid out in scripture thousands of years ago. There is a Christ and an antichrist... etc.

Curved space, based on Einstein's theory of relativity, only explains gravity on large scales.
For small gravitational interactions the math doesn't work.
Physicists think there are massless particles called gravitons that emanate gravitational fields.
For those who don't know, Einstein's theory of relativity says that time and space are woven together. Spacetime is like a fabric stretched out tight. If you place a heavy object on the fabric, it will cause the fabric to curve down where the object is. Other objects placed on the fabric will be drawn down along the curve caused by the heavy object. The closer they are to the heavy object the more pronounced the curve is.

Space is mostly a vacuum so it can't push. There is nothing to push with.

It's a bit more complex than that. And is far more evident now that we are able to detect a greater amount of the cosmos than in Albert's day.
Galileo supposed gravity to be the effect of motion.
Arthur C. Clarke "ran" with this in his novel / movie...
Not much more incredible that imagining some phantom goolies called gravitons... LOL
Some argue space is a vacuum others say otherwise. We agree it is curved and some say the math doesn't work on a smaller scale... which is what I did say that masses / bodies had to be greater than X to have the area to have this effect called gravity from the push of war (you say cannot exist).
It's the glass half full / half empty argument... what makes celestial bodies spherical? Gravity? or the push of curved space on a mass of X area or greater?

Yes it's more complicated than that, but this isn't meant to be a scientific journal.
Science does not yet know what causes gravity. It's all just theory, but Quantum Physics deserves more respect than to be called "phantom goolies".
