Dutch420 But it is the gravity, what holds the air around Earth. Gravity is real and even You can feel it on daily basis. And it does not really matter if you describe this natural phenomenon as a force (like Newton did) or a space-time deformation (like Einstein did). And guess what - You can also describe a photon both as particle and wave. These "theoretical constructs" (as You say) are based on practical observations, and proven by its applications. Seems to me that You are the one who is brainwashed.You should study physics. It's fun!
