As if he is climbing up to the sky

It was a human dream to climb up to the sky and there were many tries to do that from thousands of years, but all of them were ended by failure till the twenty century when human was able to study layers of the air and to uses that knowledge to fly and invade the space.
In a scientific way, the scientists started at the beginning of the twenty century to study the structure of the atmosphere and they proved that it consists of oxygen and nitrogen. The oxygen represents 21%of the air, the nitrogen is 78% and the other gases like carbon and water vapor are 1% of the air.
Any disturbance in these ratios will eliminate life on earth. But God's mercy had determined these ratios without any changes except in small ratios. Therefore God be He exalted made the sky as a roof to save and keep us from harmful objects in the space and also from the transmitted harmful rays from the sun.
Gravity and density laws "which were exploited by God to serve us" are dividing the atmosphere to many layers, each layer has its characteristics and benefits.
So the law of gravity holds the earth by the atmosphere during its turning. That atmosphere is attached to the earth despite the millions of years. Concerning the density law, the scientists had discovered that the heavy liquids goes down and the lighter goes up so when we mix oil with water in a cup, the oil became on the top and the water in the bottom because oil is lighter than the water. The same is applying for gases ,as the light gas goes up and the heavy one goes down, that is what happens in the atmosphere , the air which is near to the earth ground is heavier than the air in the top layered………….
Hence, the air pressure, density and weight are gradually arranged till we reach the top layer of the atmosphere where there is no air or pressure.
The diminution of oxygen in the upper layers of the sky is a known scientific fact. So that we see mountains climbers put containers which are full of oxygen on their shoulders to breath with it while climbing because oxygen decreases at the tops of the mountains. The first feeling when human ascends to a higher place is dyspnea and constriction in the lungs till he suffocates and dies. This scientific fact was unknown at the time of the descending of the Qur'an as no one at that time knew anything about what is called oxygen also no one knew that when we goes up oxygen decreases.
But the holy Qur'an described this scientific fact precisely when God be He exalted described the strayed man who is far from his God as if a human who is living in the upper layers of the atmosphere as he can't breath and always feels with dyspnea and constriction in the lungs till he reaches the maximum point where he is going to die. God says :
( and whomsoever He wills to send astray, He makes his breast closed and constricted, as if he is climbing up to the sky)
(Sûrat Al-An’âm- verse 125)
God be He exalted told us about this scientific fact from hundreds of years in concise and few words as He says:(He makes his breast closed and constricted, as if he is climbing up to the sky).
Who told prophet Mohamed about this Physical Law? And who told him that human when ascends toward the sky feels with dyspnea and constriction in the lungs?
