I always thought that SKY has no weight as when I look up it is all empty. But on google I found, the weight of the sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds, roughly 5.2 million billion tonnes.The sun is 3,33,000 times heavier than the earth.
Weight of the sky is roughly 5.2 million billion tonnes. This is approximately the same weight as 570,000,000,000,000 adult Indian elephants! The weight of one adult elephant is approx 4000 Kg.
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space. In the field of astronomy, the sky is also called the celestial sphere
The sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more visible.
Although light from the Sun looks white, it is really made up of Seven colors (Spectrum). When the Sun’s light reaches the Earth’s atmosphere it is scattered and blue light is most visible as it scatters most (short wave length).
What is effect of Weight of the sky on The earth
The weight of the sky has no direct effect on the Earth. The atmosphere, however, does exert a force on the Earth’s surface due to its own weight. This force is known as air pressure and is caused by the weight of the air molecules in the atmosphere pressing down on the Earth’s surface. This pressure can have an effect on the climate, weather, and ecosystems of the Earth by influencing winds and temperatures. Additionally, the air pressure can affect the surface of the Earth by pushing down on it, causing it to deform slightly.
What is effect of SKY weight on Human?
Air is all around us. It starts at the ground and goes up, up, up all the way to the top of the sky. All that air is not empty. It’s made up of all sorts of gas molecules. Those molecules all have weight and are responsible of weight of the SKY.
The weight is distributed evenly over Earth’s surface. The average weight of air pressing on us — called air pressure — is almost 15 pounds on each square inch of our body.
Since air moves about easily, it presses on all sides of us. If it was all just on top of your our head, it might knock us to the ground. Instead, it presses evenly all around us…even from the inside. That’s right! We breathe air into our lungs and it presses outward from our insides.
Atmospheric pressure and Blood pressure
Atmospheric pressure is the force that all the surrounding air exerts on the surface of your skin.
Blood pressure is the force that blood exerts on the inner surface of your veins/vessels etc.
Now, typically the atmospheric pressure is 760 mmHg
And a health human blood pressure is 120/80 mmHg.
Actually the inner blood pressure is 120+ 760 and 80+760.
So our blood pressure is always greater than atmospheric pressure and we are not hurt by later pressure.
What if the SKY falls?
If the sky were to fall, it would be catastrophic. The gravitational force of the entire atmosphere would cause immense damage to the planet, potentially even destroying all life on Earth. Additionally, the atmospheric pressure would be so great that the air would become unbreathable, resulting in the suffocation of any living beings.
All the oxygen, nitrogen and other stuff in Earth’s atmosphere has a whopping combined mass of 5 quadrillion tons, so a falling sky would mean that nearly 10 tons of molecules — roughly the heft of a school bus — would drop on every square meter of Earth’s surface.
However,Sky is the layer of mixture of gasses surrounded by planet-earth which is entrapped due to gravitational attraction of earth. As sky is not an object, it doesn’t fall, it just surrounds earth and separates earth from outer space…..
How big is the SKY?
Sky is unimaginably big, so big that it is impossible for anyone to comprehend the true size of it. Humans would never be able to figure out how big the sky is, which is limited by the laws of physics.
