i.e. imagine a plane that could fly into space, this plane has no roof, it is an open top. As you accelerate upwards into space, you will leave the atmosphere behind. Now imagine the plane is the earth. The same thing would happen!!!
Why would the air escape if you are accelerating? How is your example any different than the RE?
Newton thought the earth was round. And by saying what you are saying has no context or meaning here.
I didn't say Newton thought otherwise. By Newton's third law, the air is in contact with the earth, therefore, the earth provides a force to the air. Again, gravity and acceleration are locally indistinguishable.
Look, this is basic physics... i don't see why you are having such a hard time grapsing it.
A body will stay at rest or constant motion unless another force acts upon it.
The earth is "accelerating" according to you.
IF we take the atmosphere, which is a gas and consider each gas particle serperately.
The earth is moving into the particle because it is accelerating, and the particle is at rest or constant motion as no force is acting on it. But relative to the particle no matter what speed, the earth is moving towards the particle at 9.81 ms^-2.
Agreed?
Therefore when the particle hits the surface of the earth, it will initially be accelerated by the earth, but then as there is a build up of particles they will eventually run off the side of the earth, leaving the atmosphere behind.
In simple terms imagine the gas particles like marbles suspended in space, a surface is accerating towards the marbles at 9.81 ms^-2, the marbles are going to hit the surface and be accelerated temporarily, untill it runs of the surface.
Look i ll draw you a picture

how do i link pictures? this one seems to of not worked.
Understand?
And this does not happen in the RE model because the earth is a sphere. And RE believes the earth has its own gravity, that is roughly uniform on the surface of the sphere, so atmosphere is "accerated" towards the centre of the earth, thus keeping it there.
I GOT IT! The earth is surrounded by a giant glass dome that holds in the atmosphere.
glass dome? very plauseable, i mean technically when an asteroid hits the earth, it should shatter the dome and we will all suffocate.
