According to known exploration data, the deepest seabed on earth is the marianas trench, located at the bottom of the pacific ocean. The measurement data shows that the deepest part of the marianas trench can reach 11,034 meters, where the pressure is about 110 mpa, equivalent to 1.1 tons of weight per square centimeter. So the question arises, if you take a 100kg solid iron ball and sink it into the deepest part of the sea floor, will the iron ball be deformed by the pressure?

There Have Been Ways To Create Artificial Gravity For a Long Time, So Why Isn't Artificial Gravity Used On Space Stations?
If we make the space station in space into a ring and let it rotate, then the humans in it will also feel the "centrifugal force" to "push" themselves towards the outer wall of the space station

Will Humanity Be Trapped In The Solar System Forever? What Would Humanity Do Without Ftl And Wormholes?
The solar system is a system of celestial bodies kept in motion by the sun's gravity, which means that all bodies within the effective range of the sun's gravity are part of the solar system, so by this definition, how large is the solar system?

The Earth Has Mountains Over 8,000 Metres High And Ocean Trenches Over 10,000 Metres Deep, So Why Do Scientists Still Say The Earth Is Round
There is a view that the reason why the Earth looks round is because of the role of the Earth's oceans, which simply means that a large amount of seawater has "filled in" the undulations of the Earth's surface.

There Is No Air In Space To Provide Reaction Forces, So Where Does The Power To Move The Spacecraft Forward Come From?
The law of conservation of momentum means that the total momentum of a system remains constant when it is not subject to external forces or when the sum of the vectors of external forces is zero

In a good night sky, we can always see a sky full of stars and it seems to us that the whole universe is in full view. In fact, the stars we see in the night sky are only a tiny part of the milky way galaxy, which is just one of the trillions of galaxies that exist in the observable universe.
